The minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction. // A fire is not much more than a combination of carbon and oxygen, but the forests and coal mines of the world are not combusting at will because such a chemical reaction requires the input of a critical level of “activation energy” in order to get a reaction started. Two combustible elements alone are not enough.

Species tend to adapt to their surroundings in order to survive, given the combination of their genetics and their environment – an always-unavoidable combination. However, adaptations made in an individual’s lifetime are not passed down genetically, as was once thought: Populations of species adapt through the process of evolution by natural selection, as the most-fit examples of the species replicate at an above-average rate.
Predicting how happy you will be in the future contingent upon some event or change is hard. We normally guess that the magnitude of the effect will be larger than it actually is, because ) we’ve just been asked to think about that event, which makes it seem more important than it actually is in our everyday happiness, and ) we underestimate our ability to adapt.

The introduction of algebra allowed us to demonstrate mathematically and abstractly that two seemingly different things could be the same. By manipulating symbols, we can demonstrate equivalence or inequivalence, the use of which led humanity to untold engineering and technical abilities. Knowing at least the basics of algebra can allow us to understand a variety of important results.
IQ is nearly impossible to improve in healthy people without tradeoffs. If we could get smarter by a simple mechanism, like upregulating acetylcholine, which had no negative side effects (in the ancestral environment), then perhaps evolution would have upregulated acetylcholine already. We could equate this with the ‘efficient market hypothesis’ of improving brain function.
While hard to precisely define, an algorithm is generally an automated set of rules or a “blueprint” leading a series of steps or actions resulting in a desired outcome, and often stated in the form of a series of “If → Then” statements. Algorithms are best known for their use in modern computing, but are a feature of biological life as well. For example, human DNA contains an algorithm for building a human being.
When we combine various elements, we create new substances. This is no great surprise, but what can be surprising in the alloying process is that + can equal not but – the alloy can be far stronger than the simple addition of the underlying elements would lead us to believe. This process leads us to engineering great physical objects, but we understand many intangibles in the same way; a combination of the right elements in social systems or even individuals can create a += effect similar to alloying.

taking advantage of different prices between markets for the same products. // Given two markets selling an identical good, an arbitrage exists if the good can profitably be bought in one market and sold at a profit in the other. This model is simple on its face, but can present itself in disguised forms: The only gas station in a -mile radius is also an arbitrage as it can buy gasoline and sell it at the desired profit (temporarily) without interference. Nearly all arbitrage situations eventually disappear as they are discovered and exploited.

The asymmetry model leads to an application in warfare whereby one side seemingly “plays by different rules” than the other side due to circumstance. Generally, this model is applied by an insurgency with limited resources. Unable to out-muscle their opponents, asymmetric fighters use other tactics, as with terrorism creating fear that’s disproportionate to their actual destructive ability.
military strategy in which a belligerent attempts to win a war by wearing down the enemy to the point of collapse through continuous losses in personnel and material.
Aumann’s agreement theorem
If two rational agents disagree when they both have exactly the same information, one of them must be wrong. The ‘same information’ qualifier is crucial; very often disagreement is due to differences in information, not failure of rationality. So you should take disagreement seriously if you have reason to believe the other person has significant information that you don’t.
People tend to heavily weigh their judgments toward more recent information, making new opinions biased toward that latest news.
One of the most useful findings of modern psychology is what Daniel Kahneman calls the Availability Bias or Heuristic: We tend to most easily recall what is salient, important, frequent, and recent. The brain has its own energy-saving and inertial tendencies that we have little control over – the availability heuristic is likely one of them. Having a truly comprehensive memory would be debilitating. Some sub-examples of the availability heuristic include the Anchoring and Sunk Cost Tendencies.
A critical model of the engineering profession is that of backup systems. A good engineer never assumes the perfect reliability of the components of the system. He or she builds in redundancy to protect the integrity of the total system. Without the application of this robustness principle, tangible and intangible systems tend to fail over time.

the most sexually selective sex will be that which has the most costs from rearing the offspring. In humans, women have more costs associated with raising offspring (maternal mortality, breastfeeding, rearing) and are the more selective sex. In seahorses, the opposite is true: male seahorses carry the offspring in their pouch, and are more selective with those they choose to mate with.
Describes the probability of an event, based on conditions that might be related to the event. For example, suppose one is interested in whether a person has cancer, and knows the person’s age. If cancer is related to age, then, using Bayes’ theorem, information about the person’s age can be used to more accurately assess the probability that they have cancer.(related: base rate fallacy)
assigning a probability before an event, receiving evidence, and updating the probability you assigned. This is beneficial insofar as it forces us to think probabilistically. Moreover, it allows us to account for competing evidence and promotes a nuanced view, thus avoiding a simplistic black and white application of ‘good and bad’ outcomes.
The Bayesian method is a method of thought (named for Thomas Bayes) whereby one takes into account all prior relevant probabilities and then incrementally updates them as newer information arrives. This method is especially productive given the fundamentally non-deterministic world we experience: We must use prior odds and new information in combination to arrive at our best decisions. This is not necessarily our intuitive decision-making engine.
A temporary line created when a military unit reaches a landing beach by sea and begins to defend the area while other reinforcements help out until a unit large enough to begin advancing has arrived.
Bell Curve/Normal Distribution
The normal distribution is a statistical process that leads to the well-known graphical representation of a bell curve, with a meaningful central “average” and increasingly rare standard deviations from that average when correctly sampled. (The so-called “central limit” theorem.) Well-known examples include human height and weight, but it’s just as important to note that many common processes, especially in non-tangible systems like social systems, do not follow the normal distribution.
Best Alternative to a Negotiated Agreement (BATNA)
The most advantageous alternative course of action a party can take if negotiations fail and an agreement cannot be reached.
Bias from Incentives
Highly responsive to incentives, humans have perhaps the most varied and hardest to understand set of incentives in the animal kingdom. This causes us to distort our thinking when it is in our own interest to do so. A wonderful example is a salesman truly believing that his product will improve the lives of its users. It’s not merely convenient that he sells the product; the fact of his selling the product causes a very real bias in his own thinking.

Also popularized by Nassim Taleb, a Black Swan is a rare and highly consequential event that is invisible to a given observer ahead of time. It is a result of applied epistemology: If you have seen only white swans, you cannot categorically state that there are no black swans, but the inverse is not true: seeing one black swan is enough for you to state that there are black swans. Black Swan events are necessarily unpredictable to the observer (as Taleb likes to say, Thanksgiving is a Black Swan for the turkey, not the butcher) and thus must be dealt with by addressing the fragility-robustness-antifragility spectrum rather than through better methods of prediction.

A bottleneck describes the place at which a flow (of a tangible or intangible) is stopped, thus holding it back from continuous movement. As with a clogged artery or a blocked drain, a bottleneck in production of any good or service can be small but have a disproportionate impact if it is in the critical path.
Often ignored in mainstream economics, the concept of bribery is central to human systems: Given the chance, it is often easier to pay a certain agent to look the other way than to follow the rules. The enforcer of the rules is then neutralized. This principle/agent problem can be seen as a form of arbitrage.

A substance which increases the rate of a chemical reaction. (related: tipping point)
A catalyst either kick-starts or maintains a chemical reaction, but isn’t itself a reactant. The reaction may slow or stop without the addition of catalysts. Social systems, of course, take on many similar traits, and we can view catalysts in a similar light.
A sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events. (related: cascading failure, domino effect)
Chaos Dynamics (Sensitivity to Initial Conditions)
In a world such as ours, governed by chaos dynamics, small changes (perturbations) in initial conditions have massive downstream effects as near-infinite feedback loops occur; this phenomenon is also called the butterfly effect. This means that some aspects of physical systems (like the weather more than a few days from now) as well as social systems (the behavior of a group of human beings over a long period) are fundamentally unpredictable.

If you can’t see the purpose of a social norm, like whether there is any value to having family unit, you shouldn’t ignore it without having thought hard about why it is there. Asking people who endorse the family unit why it’s important and noticing their reasoning is flawed often isn’t good enough either.

Cialdini’s Six Principles of Influence
Reciprocity (People tend to return a favor.), Commitment (If people commit…they are more likely to honor that commitment.), Social Proof (People will do things they see other people are doing.), Authority (People will tend to obey authority figures.), Liking (People are easily persuaded by other people they like.), and Scarcity (Perceived scarcity will generate demand).(related: foot-in-the-door technique)
Circle of Competence
An idea introduced by Warren Buffett and Charles Munger in relation to investing: each individual tends to have an area or areas in which they really, truly know their stuff, their area of special competence. Areas not inside that circle are problematic because not only are we ignorant about them, but we may also be ignorant of our own ignorance. Thus, when we’re making decisions, it becomes important to define and attend to our special circle, so as to act accordingly.

Tendencies to think in certain ways that can lead to systematic deviations from a standard of rationality or good judgments. // these are systematic flaws in how we think. We don’t look for information that proves us wrong. We estimate that events we can easily recall (perhaps because they happened more recently, or frequently appear in the media) are more likely to occur than they are. We’re overconfident. Particularly relative to our level of expertise. And a whole bunch more. The plot thickens: it’s only our friends and colleagues who are biased. (Author’s caution: don’t become fallacy (wo)man).
holding two conflicting beliefs causes us to feel slightly uncomfortable, and to reject (at least) one of them. For instance, holding the belief that science is a useful way to discover the truth would conflict with another belief that vaccines cause autism. If you held both of these beliefs, one would have to be discarded.
Commandos vs Infantry vs Police
Three distinct groups of people that define the lifetime of a company: Commandos, Infantry, and Police: Whether invading countries or markets, the first wave of troops to see battle are the commandos…Grouping offshore as the commandos do their work is the second wave of soldiers, the infantry…But there is still a need for a military presence in the territory they leave behind, which they have liberated. These third-wave troops hate change. They aren’t troops at all but police.
Commitment & Consistency Bias
As psychologists have frequently and famously demonstrated, humans are subject to a bias towards keeping their prior commitments and staying consistent with our prior selves when possible. This trait is necessary for social cohesion: people who often change their conclusions and habits are often distrusted. Yet our bias towards staying consistent can become, as one wag put it, a “hobgoblin of foolish minds” – when it is combined with the first-conclusion bias, we end up landing on poor answers and standing pat in the face of great evidence.
Commitment and consistency
if people commit to an idea or goal, they are more likely to honour the commitment if establishing that idea or goal is consistent with their self-image. Even if the original incentive or motivation is removed after they have agreed, they will continue to honour the agreement. For example, once someone has committed themselves to a viewpoint in an argument, rarely do they change ‘sides’.
An agent has a comparative advantage over another in producing a particular good if they can produce that good at a lower relative opportunity cost or autarky price, i.e. at a lower relative marginal cost prior to trade. // The Scottish economist David Ricardo had an unusual and non-intuitive insight: Two individuals, firms, or countries could benefit from trading with one another even if one of them was better at everything. Comparative advantage is best seen as an applied opportunity cost: If it has the opportunity to trade, an entity gives up free gains in productivity by not focusing on what it does best.
Comparative vs. absolute advantage
if you are better than me at earning an income from your job and cleaning the house, you have an absolute advantage in both these activities. Does that mean that both of us are better off if you do both? Not necessarily. Suppose you earn $/hour at work, times more than my $/hour and further that you clean the house approximately twice as fast as I do. Of these two jobs, I’m ‘least bad’ at cleaning the house, so it might be (depending on the social costs that this arrangement incurs) that both of us would be better off if you paid me $ an hour to clean your house. Generally, people should do the action that they’re the least bad at, thus working to their comparative advantage.
Complex Adaptive Systems
A complex adaptive system, as distinguished from a complex system in general, is one that can understand itself and change based on that understanding. Complex adaptive systems are social systems. The difference is best illustrated by thinking about weather prediction contrasted to stock market prediction. The weather will not change based on an important forecaster’s opinion, but the stock market might. Complex adaptive systems are thus fundamentally not predictable.
Interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously-accumulated interest.
It’s been said that Einstein called compounding a wonder of the world. He probably didn’t, but it is a wonder. Compounding is the process by which we add interest to a fixed sum, which then earns interest on the previous sum and the newly added interest, and then earns interest on that amount, and so on ad infinitum. It is an exponential effect, rather than a linear, or additive, effect. Money is not the only thing that compounds; ideas and relationships do as well. In tangible realms, compounding is always subject to physical limits and diminishing returns; intangibles can compound more freely. Compounding also leads to the time value of money, which underlies all of modern finance.
Confidence intervals consist of a range of values (interval) that act as good estimates of the unknown population parameter; however, the interval computed from a particular sample does not necessarily include the true value of the parameter. (related: error bar)

On the other side, obviously where the consequences are dramatic and you have extremely high conviction that you are right, you actually can’t let your junior colleague make a mistake.

Cooperation (Including Symbiosis)
Competition tends to describe most biological systems, but cooperation at various levels is just as important a dynamic. In fact, the cooperation of a bacterium and a simple cell probably created the first complex cell and all of the life we see around us. Without cooperation, no group survives, and the cooperation of groups gives rise to even more complex versions of organization. Cooperation and competition tend to coexist at multiple levels.

Though asymmetric insurgent warfare can be extremely effective, over time competitors have also developed counterinsurgency strategies. Recently and famously, General David Petraeus of the United States led the development of counterinsurgency plans that involved no additional force but substantial additional gains. Tit-for-tat warfare or competition will often lead to a feedback loop that demands insurgency and counterinsurgency.

The USCB ecologist/economist Garrett Hardin once said that “The scientific mind is not closed: it is merely well-guarded by a conscientious and seldom sleeping gatekeeper.” The way it does that is with the concept of the default status: The “resting position” of common sense, whereby the burden of proof falls on assertions to the contrary. Given the problem of opportunity costs and limited time and energy, a default status is nearly always necessary to avoid wasting time. Examples include the laws of thermodynamics, the law of natural selection, and the incentive-caused bias.

Efficient market hypothesist
here are many people approximately as clever as you who value approximately the same things you do. It’s unlikely you’ll be walking down the street and stumble on $ sitting on the ground which no one else has picked up. In the same way, it’s unlikely you’ll be able to choose a company on the stock market that will do times better than the average company which no one else has already found and invested in (driving the cost of parts of the company (shares) up). This is the same reason why you might have a hard time finding a car park that is (i) free, (ii) right next to work, and (iii) somewhere you can park in all day. Even though such car parks do exist, over time word gets out, and they are occupied in the short term or monetised in the long term. Everything is a market. Thus, when taking the efficient market hypothesis into account, you should ) look for the things you value in places that other people have systematically failed to look, and ) think that if something looks too good to be true, it probably is.

Evolution by Natural Selection
Evolution by natural selection was once called “the greatest idea anyone ever had.” In the th century, Charles Darwin and Alfred Russel Wallace simultaneous realized that species evolve through random mutation and differential survival rates. If we call human intervention in animal-breeding an example of “artificial selection,” we can call Mother Nature deciding the success or failure of a particular mutation “natural selection.” Those best suited for survival tend to be preserved. But of course, conditions change.
Introduced by the biologist Steven Jay Gould, an exaptation refers to a trait developed for one purpose that is later used for another purpose. This is one way to explain the development of complex biological features like an eyeball; in a more primitive form, it may have been used for something else.

What a man wishes, he also believes. Similarly, what we believe is what we choose to see. This is commonly referred to as the confirmation bias. It is a deeply ingrained mental habit, both energy-conserving and comfortable, to look for confirmations of long-held wisdom rather than violations. Yet the scientific process – including hypothesis generation, blind testing when needed, and objective statistical rigor – is designed to root out precisely the opposite, which is why it works so well when followed. // The modern scientific enterprise operates under the principle of falsification: A method is termed scientific if it can be stated in such a way that a certain defined result would cause it to be proved false. Pseudo-knowledge and pseudo-science operate and propagate by being unfalsifiable – as with astrology, we are unable to prove them either correct or incorrect because the conditions under which they would be shown false are never stated.
Fat-Tailed Processes (Extremistan)
A process can often look like a normal distribution but have a large “tail” – meaning that seemingly outlier events are far more likely than they are in an actual normal distribution. A strategy or process may be far more risky than a normal distribution is capable of describing if the fat tail is on the negative side, or far more profitable if the fat tail is on the positive side. Much of the human social world is said to be fat-tailed rather than normally distributed.
Fear of Missing Out (FOMO)
A pervasive apprehension that others might be having rewarding experiences from which one is absent.
Fear, Uncertainty, and Doubt (FUD)
A disinformation strategy used in sales, marketing, public relations, politics and propaganda. FUD is generally a strategy to influence perception by disseminating negative and dubious or false information and a manifestation of the appeal to fear.
Feedback Loops (and Homeostasis)
ll complex systems are subject to positive and negative feedback loops whereby A causes B, which in turn influences A (and C), and so on – with higher-order effects frequently resulting from continual movement of the loop. In a homeostatic system, a change in A is often brought back into line by an opposite change in B to maintain the balance of the system, as with the temperature of the human body or the behavior of an organizational culture. Automatic feedback loops maintain a “static” environment unless and until an outside force changes the loop. A “runaway feedback loop” describes a situation in which the output of a reaction becomes its own catalyst (auto-catalysis).
(aka ‘back of the envelope calculation’)involves using a few guesses or known numbers to come to an educated guess about some value of interest. To illustrate, one could approximately calculate the number of piano tuners in Chicago by plugging a few estimates like population, percentage of houses with a piano, and piano tuner productivity into a calculation.
the problem we confront when we run a Fermi calculation on the number of habitable planets in our galaxy and realise how weird it is that we seem to be alone. It leads to some interesting conclusions.
Fighting the Last War
Using strategies and tactics that worked successfully in the past, but are no longer as useful.
Filling a Vacuum
A vacuum is space void of matter. Filling a vacuum refers to the fact that if a vacuum is put next to something with pressure, it will be quickly filled by the gas producing that pressure.(related: power vacuum)
In which a website algorithm selectively guesses what information a user would like to see based on information about the user (such as location, past click behavior and search history) and, as a result, users become separated from information that disagrees with their viewpoints, effectively isolating them in their own cultural or ideological bubbles.(related: echo chamber)
As Charlie Munger famously pointed out, the mind works a bit like a sperm and egg: the first idea gets in and then the mind shuts. Like many other tendencies, this is probably an energy-saving device. Our tendency to settle on first conclusions leads us to accept many erroneous results and cease asking questions; it can be countered with some simple and useful mental routines.
First-mover advantage vs First-mover disadvantage

A forcing function is any task, activity or event that forces you to take action and produce a result.
Fragility – Robustness – Antifragility
Popularized by Nassim Taleb, the sliding scale of fragility, robustness, and antifragility refers to the responsiveness of a system to incremental negative variability. A fragile system or object is one in which additional negative variability has a disproportionately negative impact, as with a coffee cup shattering from a -foot fall, but receiving no damage at all (rather than /th of the damage) from a -foot fall. A robust system or object tends to be neutral to the additional negativity variability, and of course, an antifragile system benefits: If there were a cup that got stronger when dropped from feet than when dropped from foot, it would be termed antifragile.

At this point, all hope of meaningful conversation is lost, and the discussion must stop.
Goodhart’s law/ Campbell’s law
what gets measured, gets managed (and then fails to be a good measure of what it was originally intended for). If we use GDP as a measure of prosperity of a nation, and there are incentives to show that prosperity is increasing, then nations could ‘hack’ this metric. In turn, this may raise GDP while failing to improve the living conditions in the country.
Gresham’s Law, named for the financier Thomas Gresham, states that in a system of circulating currency, forged currency will tend to drive out real currency, as real currency is hoarded and forged currency is spent. We see a similar result in human systems, as with bad behavior driving out good behavior in a crumbling moral system, or bad practices driving out good practices in a crumbling economic system. Generally, regulation and oversight are required to prevent results that follow Gresham’s Law.
Gross Domestic Product (GDP)
A monetary measure of the market value of all final goods and services produced in a period (quarterly or yearly).
Growth Mindset vs Fixed Mindset
Those with a ‘fixed mindset’ believe that abilities are mostly innate and interpret failure as the lack of necessary basic abilities, while those with a ‘growth mindset’ believe that they can acquire any given ability provided they invest effort or study.

Harder to trace in its origin, Hanlon’s Razor states that we should not attribute to malice that which is more easily explained by stupidity. In a complex world, this principle helps us avoid extreme paranoia and ideology, often very hard to escape from, by not generally assuming that bad results are the fault of a bad actor, although they can be. More likely, a mistake has been made.
Never attribute to malice that which is adequately explained by carelessness.(related: fundamental attribution error- the tendency for people to place an undue emphasis on internal characteristics of the agent (character or intention), rather than external factors, in explaining another person’s behavior in a given situation.)

Heisenberg Uncertainty Principle
A fundamental limit to the precision with which certain pairs of physical properties of a particle, known as complementary variables, such as position x and momentum p, can be known.
we use rules of thumb to make decisions under conditions of uncertainty (which turns out to be almost every single decision we make). This is both a blessing and a curse. It’s quicker, useful when we don’t have much information we could deal with explicitly. But also by its nature requires us to make generalisations that might not turn out to be true. It pays to notice that we are using them because they can be wrong.
Increasing the number of choices will increase the decision time logarithmically.
Hierarchical and Other Organizing Instincts
Most complex biological organisms have an innate feel for how they should organize. While not all of them end up in hierarchical structures, many do, especially in the animal kingdom. Human beings like to think they are outside of this, but they feel the hierarchical instinct as strongly as any other organism.
High-context vs Low-context Culture
In a higher-context culture, many things are left unsaid, letting the culture explain. Words and word choice become very important in higher-context communication, since a few words can communicate a complex message very effectively to an in-group (but less effectively outside that group), while in a low-context culture, the communicator needs to be much more explicit and the value of a single word is less important.
The inclination, after an event has occurred, to see the event as having been predictable, despite there having been little or no objective basis for predicting it. (related: Pollyanna principle-tendency for people to remember pleasant items more accurately than unpleasant ones) // Once we know the outcome, it’s nearly impossible to turn back the clock mentally. Our narrative instinct leads us to reason that we knew it all along (whatever “it” is), when in fact we are often simply reasoning post-hoc with
information not available to us before the event. The hindsight bias explains why it’s wise to keep a journal of important decisions for an unaltered record and to re-examine our beliefs when we convince ourselves that we knew it all along.
Hunting Elephants vs Flies
Salespeople sometimes refer to ‘elephants’, ‘deers’ and ‘rabbits’ when they talk about the first three categories of customers. To extend the metaphor to the th and th type of customer, let’s call them ‘mice and flies’. So how can you hunt , elephants, deers, rabbits, mice or flies? (related: brontosaurus, whale, and microbe)
Illusion of transparency
we tend to overestimate how much our mental state is known by others, a fact not helped by the ambiguity of the English language. “Elizabeth Newton created a simple test that she regarded as an illustration of the phenomenon. She would tap out a well-known song, such as “Happy Birthday” or the national anthem, with her finger and have the test subject guess the song. People usually estimate that the song will be guessed correctly in about percent of the tests, but only percent pick the correct song. The tapper can hear every note and the lyrics in his or her head; however, the observer, with no access to what the tapper is thinking, only hears a rhythmic tapping.”

Something that motivates an individual to perform an action. (related: carrot and stick-a policy of offering a combination of rewards and punishment to induce behavior.) // All creatures respond to incentives to keep themselves alive. This is the basic insight of biology. Constant incentives will tend to cause a biological entity to have constant behavior, to an extent. Humans are included and are particularly great examples of the incentive-driven nature of biology; however, humans are complicated in that their incentives can be hidden or intangible. The rule of life is to repeat what works and has been rewarded.
the resistance of any physical object to any change in its state of motion; this includes changes to its speed, direction or state of rest. It is the tendency of objects to keep moving in a straight line at constant velocity. (related: strategy tax-sometimes products developed inside a company…have to accept constraints that go against competitiveness, or might displease users, in order to further the cause of another product.; flywheel-a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed.) // An object in motion with a certain vector wants to continue moving in that direction unless acted upon. This is a fundamental physical principle of motion; however, individuals, systems, and organizations display the same effect. It allows them to minimize the use of energy, but can cause them to be destroyed or eroded.

Influence of Authority
The equally famous Stanford Prison Experiment and Milgram Experiments demonstrated what humans had learned practically many years before: the human bias towards being influenced by authority. In a dominance hierarchy such as ours, we tend to look to the leader for guidance on behavior, especially in situations of stress or uncertainty. Thus, authority figures have a responsibility to act well, whether they like it or not.
Influence of Stress (Including Breaking Points)
Stress causes both mental and physiological responses and tends to amplify the other biases. Almost all human mental biases become worse in the face of stress as the body goes into a fight-or-flight response, relying purely on instinct without the emergency brake of Daniel Kahneman’s “System ” type of reasoning. Stress causes hasty decisions, immediacy, and a fallback to habit, thus giving rise to the elite soldiers’ motto: “In the thick of battle, you will not rise to the level of your expectations, but fall to the level of your training.”

Otherwise known as thinking through a situation in reverse or thinking “backwards,” inversion is a problem-solving technique. Often by considering what we want to avoid rather than what we want to get, we come up with better solutions. Inversion works not just in mathematics but in nearly every area of life. As the saying goes, “Just tell me where I’m going to die so I can never go there.”
Investing vs Speculation
Typically, high-risk trades that are almost akin to gambling fall under the umbrella of speculation, whereas lower-risk investments based on fundamentals and analysis fall into the category of investing.
IQ vs EQ
is a total score derived from one of several standardized tests designed to assess human intelligence. EQ is the capacity of individuals to recognize their own, and other people’s emotions, to discriminate between different feelings and label them appropriately, and to use emotional information to guide thinking and behavior.
We find that in most systems there are irreducible quantitative properties, such as complexity, minimums, time, and length. Below the irreducible level, the desired result simply does not occur. One cannot get several women pregnant to reduce the amount of time needed to have one child, and one cannot reduce a successfully built automobile to a single part. These results are, to a defined point, irreducible.
Jobs To Be Done
Consumers usually don’t go about their shopping by conforming to particular segments. Rather, they take life as it comes. And when faced with a job that needs doing, they essentially ‘hire’ a product to do that job.
he psychologist Steven Pinker calls our DNA-level instinct to learn grammatically constructed language the Language Instinct. The idea that grammatical language is not a simple cultural artifact was first popularized by the linguist Noam Chomsky. As we saw with the narrative instinct, we use these instincts to create shared stories, as well as to gossip, solve problems, and fight, among other things. Grammatically ordered language theoretically carries infinite varying meaning.
Law of Diminishing Returns
Related to scale, most important real-world results are subject to an eventual decrease of incremental value. A good example would be a poor family: Give them enough money to thrive, and they are no longer poor. But after a certain point, additional money will not improve their lot; there is a clear diminishing return of additional dollars at some roughly quantifiable point. Often, the law of diminishing returns veers into negative territory – i.e., receiving too much money could destroy the poor family.
Law of Large Numbers
One of the fundamental underlying assumptions of probability is that as more instances of an event occur, the actual results will converge on the expected ones. For example, if I know that the average man is feet inches tall, I am far more likely to get an average of by selecting men at random than men at random. The opposite of this model is the law of small numbers, which states that small samples can and should be looked at with great skepticism.
Laws of Thermodynamics
The laws of thermodynamics describe energy in a closed system. The laws cannot be escaped and underlie the physical world. They describe a world in which useful energy is constantly being lost, and energy cannot be created or destroyed. Applying their lessons to the social world can be a profitable enterprise.

In practical life outside of physical engineering, we can often profitably give ourselves margins as robust as the bridge system.
what are extra resources worth? If you have no bananas, and you get a banana, it’s probably worth more to you than if you already had one million bananas and you get an extra. This is an important concept because it might lead to the realisation that not all the bananas hold the same value to you. Slightly less trivially, what matters with your charitable donation is what happens with that donation, not the average of what the charity achieves. Extra donations to distribute bed nets could do more once there are already the distribution lines established, so it could achieve more.

Market was introduced by the investor Benjamin Graham in his seminal book The Intelligent Investor to represent the vicissitudes of the financial markets. As Graham explains, the markets are a bit like a moody neighbor, sometimes waking up happy and sometimes waking up sad – your job as an investor is to take advantage of him in his bad moods and sell to him in his good moods. This attitude is contrasted to an efficient-market hypothesis in which Mr. Market always wakes up in the middle of the bed, never feeling overly strong in either direction.
Multiplying by Zero
Any reasonably educated person knows that any number multiplied by zero, no matter how large the number, is still zero. This is true in human systems as well as mathematical ones. In some systems, a failure in one area can negate great effort in all other areas. As simple multiplication would show, fixing the “zero” often has a much greater effect than does trying to enlarge the other areas.

Mutually Assured Destruction
In which a full-scale use of nuclear weapons by two or more opposing sides would cause the complete annihilation of both the attacker and the defender. It is based on the theory of deterrence, which holds that the threat of using strong weapons against the enemy prevents. (related: Mexican standoff, Zugzwang) // Somewhat paradoxically, the stronger two opponents become, the less likely they may be to destroy one another. This process of mutually assured destruction occurs not just in warfare, as with the development of global nuclear warheads, but also in business, as with the avoidance of destructive price wars between competitors. However, in a fat-tailed world, it is also possible that mutually assured destruction scenarios simply make destruction more severe in the event of a mistake (pushing destruction into the “tails” of the distribution).
Human beings have been appropriately called “the storytelling animal” because of our instinct to construct and seek meaning in narrative. It’s likely that long before we developed the ability to write or to create objects, we were telling stories and thinking in stories. Nearly all social organizations, from religious institutions to corporations to nation-states, run on constructions of the narrative instinct.

The effect that one user of a good or service has on the value of that product to other people. When a network effect is present, the value of a product or service is dependent on the number of others using it. // A network tends to become more valuable as nodes are added to the network: this is known as the network effect. An easy example is contrasting the development of the electricity system and the telephone system. If only one house has electricity, its inhabitants have gained immense value, but if only one house has a telephone, its inhabitants have gained nothing of use. Only with additional telephones does the phone network gain value. This network effect is widespread in the modern world and creates immense value for organizations and customers alike.
Most organisms find a niche: a method of competing and behaving for survival. Usually, a species will select a niche for which it is best adapted. The danger arises when multiple species begin competing for the same niche, which can cause an extinction – there can be only so many species doing the same thing before limited resources give out.

Open Platform vs Closed Platform
A closed platform, walled garden or closed ecosystem is a software system where the carrier or service provider has control over applications, content, and media, and restricts convenient access to non-approved applications or content. This is in contrast to an open platform, where consumers generally have unrestricted access to applications, content, and much more.
The value of the best alternative forgone where, given limited resources, a choice needs to be made between several mutually exclusive alternatives. Assuming the best choice is made, it is the ‘cost’ incurred by not enjoying the benefit that would have been had by taking the second best available choice. (related: cost of capital) // when we choose to take one option, we are implicitly not taking another. If you only have enough room for one meal and your favourite is the Pad Thai, you choose it. But this means you can’t also get the Massaman curry (your second favourite). Economists call this your opportunity cost — your choice minus the benefits of the next best alternative. Opportunity costs are everywhere and form a critical part of decision making. If you’re not donating to the very best charity, you’re not helping others as much as possible. Furthermore, if you don’t spend your time in the best way possible, that is coming at a cost. // Doing one thing means not being able to do another. We live in a world of trade-offs, and the concept of opportunity cost rules all. Most aptly summarized as “there is no such thing as a free lunch.

Named for Italian polymath Vilfredo Pareto, who noticed that % of Italy’s land was owned by about % of its population, the Pareto Principle states that a small amount of some phenomenon causes a disproportionately large effect. The Pareto Principle is an example of a power-law type of statistical distribution – as distinguished from a traditional bell curve – and is demonstrated in various phenomena ranging from wealth to city populations to important human habits.

One of the most common processes that does not fit the normal distribution is that of a power law, whereby one quantity varies with another’s exponent rather than linearly. For example, the Richter scale describes the power of earthquakes on a power-law distribution scale: an is x more destructive than a , and a is x more destructive than an . The central limit theorem does not apply and there is thus no “average” earthquake. This is true of all power-law distributions.

Preferential Attachment (Cumulative Advantage)
A preferential attachment situation occurs when the current leader is given more of the reward than the laggards, thereby tending to preserve or enhance the status of the leader. A strong network effect is a good example of preferential attachment; a market with x more buyers and sellers than the next largest market will tend to have a preferential attachment dynamic.

The measurement of how responsive an economic variable is to a change in another. It gives answers to questions such as ‘If I lower the price of a product, how much more will sell?’(related: Giffen good-a product that people consume more of as the price rises and vice versa.)
A standard example of a game analyzed in game theory that shows why two completely ‘rational’ individuals might not cooperate, even if it appears that it is in their best interests to do so. (related: Nash equilibrium, evolutionarily stable strategy) // The Prisoner’s Dilemma is a famous application of game theory in which two prisoners are both better off cooperating with each other, but if one of them cheats, the other is better off cheating. Thus the dilemma. This model shows up in economic life, in war, and in many other areas of practical human life. Though the prisoner’s dilemma theoretically leads to a poor result, in the real world, cooperation is nearly always possible and must be explored. // a problem in game theory that explains a lot of real world problems. In this situation, there are two players choosing between cooperating and not cooperating. You both do well if you both cooperate. But if you don’t cooperate while the other player tries to cooperate, you do even better. If both of you don’t cooperate then neither of you do well. But if you’re the chump who tries to cooperate while the other player doesn’t, you get screwed worst of all. Examples of this include countries individually benefitting economically from not limiting their carbon emissions, to everyone’s detriment;
(See also: Numeracy/Bayesian Updating)The unknowable human world is dominated by probabilistic outcomes, as distinguished from deterministic ones.

Proximate vs Root Cause
A proximate cause is an event which is closest to, or immediately responsible for causing, some observed result. This exists in contrast to a higher-level ultimate cause (or distal cause) which is usually thought of as the ‘real’ reason something occurred.(related: whys-to determine the root cause of a defect or problem by repeating the question ‘Why?’)

Though the human brain has trouble comprehending it, much of the world is composed of random, non-sequential, non-ordered events. We are “fooled” by random effects when we attribute causality to things that are actually outside of our control. If we don’t course-correct for this fooled-by-randomness effect – our faulty sense of pattern-seeking – we will tend to see things as being more predictable than they are and act accordingly.
If I push on a wall, physics tells me that the wall pushes back with equivalent force. In a biological system, if one individual acts on another, the action will tend to be reciprocated in kind. And of course, human beings act with intense reciprocity demonstrated as well.
Red Queen hypothesis

Regression to the Mean
The phenomenon that if a variable is extreme on its first measurement, it will tend to be closer to the average on its second measurement. (related: Pendulum swing; variance; Gambler’s fallacy) // In a normally distributed system, long deviations from the average will tend to return to that average with an increasing number of observations: the so-called Law of Large Numbers. We are often fooled by regression to the mean, as with a sick patient improving spontaneously around the same time they begin taking an herbal remedy, or a poorly performing sports team going on a winning streak. We must be careful not to confuse statistically likely events with causal ones.
Regression toward the mean
if you get an extreme result (in a normal distribution) once, additional results are likely to be closer to the average selection. If one trial suggests that health supplement x is amazingly better than all the others, you shouldn’t put all your faith in that result.

Relative Satisfaction/Misery Tendencies
The envy tendency is probably the most obvious manifestation of the relative satisfaction tendency, but nearly all studies of human happiness show that it is related to the state of the person relative to either their past or their peers, not absolute. These relative tendencies cause us great misery or happiness in a very wide variety of objectively different situations and make us poor predictors of our own behavior and feelings.
Relativity has been used in several contexts in the world of physics, but the important aspect to study is the idea that an observer cannot truly understand a system of which he himself is a part. For example, a man inside an airplane does not feel like he is experiencing movement, but an outside observer can see that movement is occurring. This form of relativity tends to affect social systems in a similar way.
he renormalization group technique allows us to think about physical and social systems at different scales. An idea from physics, and a complicated one at that, the application of a renormalization group to social systems allows us to understand why a small number of stubborn individuals can have a disproportionate impact if those around them follow suit on increasingly large scales.
A fundamental building block of diverse biological life is high-fidelity replication. The fundamental unit of replication seems to be the DNA molecule, which provides a blueprint for the offspring to be built from physical building blocks. There are a variety of replication methods, but most can be lumped into sexual and asexual.
Failure to Account for Base RatesAn unconscious failure to look at past odds in determining current or future behavior.b. Tendency to StereotypeThe tendency to broadly generalize and categorize rather than look for specific nuance. Like availability, this is generally a necessary trait for energy-saving in the brain.c. Failure to See False ConjunctionsMost famously demonstrated by the Linda Test, the same two psychologists showed that students chose more vividly described individuals as more likely to fit into a predefined category than individuals with broader, more inclusive, but less vivid descriptions, even if the vivid example was a mere subset of the more inclusive set. These specific examples are seen as more representative of the category than those with the broader but vaguer descriptions, in violation of logic and probability.
A wide range of cognitive biases that influence the responses of participants away from an accurate or truthful response.
talk is cheap, and our actions reveal more about our preferences than we’d like to believe. For instance, although I might say that Marmite is my favourite spread to put on toast, I actually buy Vegemite (#justaustralianthings). As such, my actions reveal what I really prefer.
Reversible vs Irreversible Decisions
For reversible decisions: If the decision was a bad call you can unwind it in a reasonable period of time. An irreversible decision is firing an employee, launching your product, a five-year lease for an expensive new building, etc. These are usually difficult or impossible to reverse.(related: Jeff Bezos on Type , Type decisions)
You go to war with the Army you have. They’re not the Army you might want or wish to have at a later time. (related: Joy’s law-no matter who you are, most of the smartest people work for someone else.; Effectuation)
One of the most important principles of systems is that they are sensitive to scale. Properties (or behaviors) tend to change when you scale them up or down. In studying complex systems, we must always be roughly quantifying – in orders of magnitude, at least – the scale at which we are observing, analyzing, or predicting the system.
Game theory describes situations of conflict, limited resources, and competition. Given a certain situation and a limited amount of resources and time, what decisions are competitors likely to make, and which should they make? One important note is that traditional game theory may describe humans as more rational than they really are. Game theory is theory, after all.
A process of analyzing possible future events by considering alternative possible outcomes. (related: Skate to where the puck is going.; black swan theory-a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight.)
a natural point that people will converge upon independently. For instance, if you and I have to meet in Sydney on a particular day, and we don’t know when or where, we might go to where we normally meet, or fall back on meeting at the Opera House at PM.

In all human systems and most complex systems, the second layer of effects often dwarfs the first layer, yet often goes unconsidered. In other words, we must consider that effects have effects. Second-order thinking is best illustrated by the idea of standing on your tiptoes at a parade: Once one person does it, everyone will do it in order to see, thus negating the first tiptoer. Now, however, the whole parade audience suffers on their toes rather than standing firmly on their whole feet.
Every one of today’s most famous and familiar ideas was once unknown and unsuspected…There are many more secrets left to find, but they will yield only to relentless searchers.
Seeing the Front
One of the most valuable military tactics is the habit of “personally seeing the front” before making decisions – not always relying on advisors, maps, and reports, all of which can be either faulty or biased. The Map/Territory model illustrates the problem with not seeing the front, as does the incentive model. Leaders of any organization can generally benefit from seeing the front, as not only does it provide firsthand information, but it also tends to improve the quality of secondhand information.
Seizing the Middle
In chess, the winning strategy is usually to seize control of the middle of the board, so as to maximize the potential moves that can be made and control the movement of the maximal number of pieces. The same strategy works profitably in business, as can be demonstrated by John D. Rockefeller’s control of the refinery business in the early days of the oil trade and Microsoft’s control of the operating system in the early days of the software trade.
The selection of individuals, groups or data for analysis in such a way that proper randomization is not achieved, thereby ensuring that the sample obtained is not representative of the population intended to be analyzed.(related: sampling bias)
Without a strong self-preservation instinct in an organism’s DNA, it would tend to disappear over time, thus eliminating that DNA. While cooperation is another important model, the self-preservation instinct is strong in all organisms and can cause violent, erratic, and/or destructive behavior for those around them.
Not evaluating evidence on the basis of its merits and instead rejecting it because it contradicts existing norms, beliefs and paradigms.Similar to the status quo bias (which one might choose to combat with the reversal test).
The study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be apportioned to different sources of uncertainty in its inputs.
Sensitivity to Fairness
Justice runs deep in our veins. In another illustration of our relative sense of well-being, we are careful arbiters of what is fair. Violations of fairness can be considered grounds for reciprocal action, or at least distrust. Yet fairness itself seems to be a moving target. What is seen as fair and just in one time and place may not be in another. Consider that slavery has been seen as perfectly natural and perfectly unnatural in alternating phases of human existence.
Short-termism refers to an excessive focus on short-term results at the expense of long-term interests.
the idea that an action conveys information to someone about the actor. Buying an expensive wedding ring conveys that you don’t think you’re about to run off immediately after the wedding (lest you lose three months of
your salary). Countersignalling is when the information you’re trying to signal is so obvious that you need not have signalled in the first place. For instance, Warren Buffett doesn’t need to drive around in a Ferrari to signal how rich he is.
Simple Physiological Reward-Seeking
All organisms feel pleasure and pain from simple chemical processes in their bodies which respond predictably to the outside world. Reward-seeking is an effective survival-promoting technique on average. However, those same pleasure receptors can be co-opted to cause destructive behavior, as with drug abuse.
A paradox in probability and statistics, in which a trend appears in different groups of data but disappears or reverses when these groups are combined.

Asserting that if we allow A to happen, then Z will eventually happen too, therefore A should not happen. (related: broken windows theory-maintaining and monitoring urban environments to prevent small crimes such as vandalism, public drinking, and toll-jumping helps to create an atmosphere of order and lawfulness, thereby preventing more serious crimes from happening.)
moral judgements are made predominantly on the basis of intuition, which is followed by rationalisation. For example, slavery was previously a social norm and thought to be acceptable. When asked a question (“is slavery good?”), proponents of slavery introspected an answer (“yes”), and confabulated a reason (“because they’re not actually human” or similar atrocious falsehoods). As this example shows, blind faith in our intuitions can be harmful and counterproductive, because they can be easily corrupted by immoral social norms. It wasn’t just that proponents of slavery got the wrong answer: they had — and we still have — the wrong process.
Social Proof (Safety in Numbers)
Human beings are one of many social species, along with bees, ants, and chimps, among many more. We have a DNA-level instinct to seek safety in numbers and will look for social guidance of our behavior. This instinct creates a cohesive sense of cooperation and culture which would not otherwise be possible, but also leads us to do foolish things if our group is doing them as well.
Social vs Market Norms
People are happy to do things occasionally when they are not paid for them. In fact there are some situations in which work output is negatively affected by payment of small amounts of money.

Specialization (Pin Factory)
Another Scottish economist, Adam Smith, highlighted the advantages gained in a free-market system by specialization. Rather than having a group of workers each producing an entire item from start to finish, Smith explained that it’s usually far more productive to have each of them specialize in one aspect of production. He also cautioned, however, that each worker might not enjoy such a life; this is a trade-off of the specialization model.
Sphere of Influence
A spatial region or concept division over which a state or organization has a level of cultural, economic, military, or political exclusivity, accommodating to the interests of powers outside the borders of the state that controls it.
A system is spring-loaded if it is coiled in a certain direction, positive or negative. Positively spring-loading systems and relationships is important in a fundamentally unpredictable world to help protect us against negative events. The reverse can be very destructive.
Stochastic Processes (Poisson, Markov, Random Walk)
A stochastic process is a random statistical process and encompasses a wide variety of processes in which the movement of an individual variable can be impossible to predict but can be thought through probabilistically. The wide variety of stochastic methods helps us describe systems of variables through probabilities without necessarily being able to determine the position of any individual variable over time. For example, it’s not possible to predict stock prices on a day-to-day basis, but we can describe the probability of various distributions of their movements over time. Obviously, it is much more likely that the stock market (a stochastic process) will be up or down % in a day than up or down %, even though we can’t predict what tomorrow will bring.

Supply and Demand
An economic model of price determination in a market. It concludes that in a competitive market, the unit price for a particular good, or other traded item such as labor or liquid financial assets, will vary until it settles at a point where the quantity demanded (at the current price) will equal the quantity supplied (at the current price), resulting in an economic equilibrium for price and quantity transacted. // The basic equation of biological and economic life is one of limited supply of necessary goods and competition for those goods. Just as biological entities compete for limited usable energy, so too do economic entities compete for limited customer wealth and limited demand for their products. The point at which supply and demand for a given good are equal is called an equilibrium; however, in practical life, equilibrium points tend to be dynamic and changing, never static.
The logical error of concentrating on the people or things that ‘survived’ some process and inadvertently overlooking those that did not because of their lack of visibility. // A major problem with historiography – our interpretation of the past – is that history is famously written by the victors. We do not see what Nassim Taleb calls the “silent grave” – the lottery ticket holders who did not win. Thus, we over-attribute success to things done by the successful agent rather than to randomness or luck, and we often learn false lessons by exclusively studying victors without seeing all of the accompanying losers who acted in the same way but were not lucky enough to succeed.

System & System thinking
when we’re making decisions, we use two different systems. System is fast and subconscious, often described as our ‘gut feeling’. It has an edge in social situations or when time is a limiting factor. System is slower and more methodical, better with models and numbers, and deliberate.
By taking the overall system as well as its parts into account systems thinking is designed to avoid potentially contributing to further development of unintended consequences.

A concept in programming that reflects the extra development work that arises when code that is easy to implement in the short run is used instead of applying the best overall solution.
Tendency to Distort Due to Liking/Loving or Disliking/Hating
Based on past association, stereotyping, ideology, genetic influence, or direct experience, humans have a tendency to distort their thinking in favor of people or things that they like and against people or things they dislike. This tendency leads to overrating the things we like and underrating or broadly categorizing things we dislike, often missing crucial nuances in the process.
Tendency to Feel Envy & Jealousy
Humans have a tendency to feel envious of those receiving more than they are, and a desire “get what is theirs” in due course. The tendency towards envy is strong enough to drive otherwise irrational behavior, but is as old as humanity itself. Any system ignorant of envy effects will tend to self-immolate over time.
Tendency to Minimize Energy Output (Mental & Physical)
In a physical world governed by thermodynamics and competition for limited energy and resources, any biological organism that was wasteful with energy would be at a severe disadvantage for survival. Thus, we see in most instances that behavior is governed by a tendency to minimize energy usage when at all possible.
Tendency to Overestimate Consistency of Behavior (Fundamental Attribution Error)
We tend to over-ascribe the behavior of others to their innate traits rather than to situational factors, leading us to overestimate how consistent that behavior will be in the future. In such a situation, predicting behavior seems not very difficult. Of course, in practice this assumption is consistently demonstrated to be wrong, and we are consequently surprised when others do not act in accordance with the “innate” traits we’ve endowed them with.
Tendency to Overgeneralize from Small Samples
It’s important for human beings to generalize; we need not see every instance to understand the general rule, and this works to our advantage. With generalizing, however, comes a subset of errors when we forget about the Law of Large Numbers and act as if it does not exist. We take a small number of instances and create a general category, even if we have no statistically sound basis for the conclusion.
Tendency to Want to Do Something (Fight/Flight, Intervention, Demonstration of Value, etc.)
We might term this Boredom Syndrome: Most humans have the tendency to need to act, even when their actions are not needed. We also tend to offer solutions even when we do not enough knowledge to solve the problem.
The Lindy Effect
The Lindy Effect refers to the life expectancy of a non-perishable object or idea being related to its current lifespan. If an idea or object has lasted for X number of years, it would be expected (on average) to last another X years. Although a human being who is and lives to does not add years to his or her life expectancy, non-perishables lengthen their life expectancy as they continually survive. A classic text is a prime example: if humanity has been reading Shakespeare’s plays for years, it will be expected to read them for another .
The Map Is Not the Territory
The map of reality is not reality itself. If any map were to represent its actual territory with perfect fidelity, it would be the size of the territory itself. Thus, no need for a map! This model tells us that there will always be an imperfect relationship between reality and the models we use to represent and understand it. This imperfection is a necessity in order to simplify. It is all we can do to accept this and act accordingly.
The Principle of Parsimony (Occam’s Razor)
Named after the friar William of Ockham, Occam’s Razor is a heuristic by which we select among competing explanations. Ockham stated that we should prefer the simplest explanation with the least moving parts: it is easier to falsify (see: Falsification), easier to understand, and more likely, on average, to be correct. This principle is not an iron law but a tendency and a mindset: If all else is equal, it’s more likely that the simple solution suffices. Of course, we also keep in mind Einstein’s famous idea (even if apocryphal) that “an idea should be made as simple as possible, but no simpler.”
The Red Queen Effect (Co-evolutionary Arms Race)
The evolution-by-natural-selection model leads to something of an arms race among species competing for limited resources. When one species evolves an advantageous adaptation, a competing species must respond in kind or fail as a species. Standing pat can mean falling behind. This arms race is called the Red Queen Effect for the character in Alice in Wonderland who said, “Now, here, you see, it takes all the running you can do, to keep in the same place.”

Time value of money
we’d prefer to have $ today than tomorrow, or in a year’s time. In a real sense, this implies that money today is worth more than money in the future. This preference comes from the opportunities we have to invest it at (say) % interest and gain $ in that year. How much less you’d be willing to receive now than in a year, is the discount rate (which is % in this example).

Trademarks, Patents, and Copyrights
These three concepts, along with other related ones, protect the creative work produced by enterprising individuals, thus creating additional incentives for creativity and promoting the creative-destruction model of capitalism. Without these protections, information and creative workers have no defense against their work being freely distributed.
Tragedy of the Commons
A concept introduced by the economist and ecologist Garrett Hardin, the Tragedy of the Commons states that in a system where a common resource is shared, with no individual responsible for the wellbeing of the resource, it will tend to be depleted over time. The Tragedy is reducible to incentives: Unless people collaborate, each individual derives more personal benefit than the cost that he or she incurs, and therefore depletes the resource for fear of missing out.
After a fruitless -year siege, the Greeks constructed a huge wooden horse, and hid a select force of men inside. The Greeks pretended to sail away, and the Trojans pulled the horse into their city as a victory trophy. That night the Greek force crept out of the horse and opened the gates for the rest of the Greek army, which had sailed back under cover of night. The Greeks entered and destroyed.
Fundamentally, the modern world operates on trust. Familial trust is generally a given (otherwise we’d have a hell of a time surviving), but we also choose to trust chefs, clerks, drivers, factory workers, executives, and many others.

Holding that the best moral action is the one that maximizes utility.
Utility (Marginal, Diminishing, Increasing)
The usefulness of additional units of any good tends to vary with scale. Marginal utility allows us to understand the value of one additional unit, and in most practical areas of life, that utility diminishes at some point. On the other hand, in some cases, additional units are subject to a “critical point” where the utility function jumps discretely up or down. As an example, giving water to a thirsty man has diminishing marginal utility with each additional unit, and can eventually kill him with enough units.
Veil of Ignorance
A method of determining the morality of a certain issue (e.g., slavery) based upon the following thought experiment: parties to the original position know nothing about the particular abilities, tastes, and positions individuals will have within a social order. When such parties are selecting the principles for distribution of rights, positions, and resources in the society in which they will live, the veil of ignorance prevents them from knowing who will receive a given distribution of rights, positions, and resources in that society.
Via Negativa – Omission/Removal/Avoidance of Harm
In many systems, improvement is at best, or at times only, a result of removing bad elements rather than of adding good elements. This is a credo built into the modern medical profession: First, do no harm. Similarly, if one has a group of children behaving badly, removal of the instigator is often much more effective than any form of punishment meted out to the whole group.
