A growing collection of ideas for understanding the world — and your own thinking.
Erikson portrays Yellow anger as building gradually through expression, gestures, and voice. In his account, a person may feel guilty afterward and try to make amends, though defensiveness can complicate the exchange.
Reds are not typical relational people and may appear cold or uninterested, but they care as much as anyone. Their communication is direct and they lose interest once they have the necessary information, which can be misinterpreted by more relational personality types.
Embracing uncertainty and acknowledging 'I'm not sure' is crucial for good decision-making, as it allows for a more accurate representation of the world and avoids black-and-white thinking. Treat uncertainty as a natural part of decision-making, as poker players and experts do when estimating probabilities.
In Erikson’s color framework, Blue describes a concern for accuracy, quality and honesty. His examples show repeated questions tracing a defect to purchasing decisions, and a seller disclosing faults even at a personal cost.
A cognitive bias in project planning where people systematically underestimate completion time and costs because they focus on internal project factors and neglect external uncertainties, a phenomenon called 'tunneling.' Even without incentives, planners are too narrow-minded to account for 'unknown unknowns,' leading to delays and overruns.
Erikson describes Greens as putting the group’s needs ahead of their own and hesitating to ask for help. His colleague Kristoffer illustrates the pattern: he offers advice during a phone call before revealing that he is locked outside in freezing weather.
A decision-making framework that uses mental time travel to gain perspective by imagining how a decision or outcome will feel in 10 minutes, 10 months, and 10 years, helping to reduce emotional overreaction and improve long-term thinking.
The 10/10/10 framework helps you gain perspective on decisions by asking how you will feel about them in 10 minutes, 10 months, and 10 years. It downplays short-term emotions to focus on long-term values.
A book by Charles Holm that catalogs 25 common cognitive biases, challenging the notion of human rationality.
This chapter discusses the disjunction fallacy—a violation of probability rules where people judge a disjunction (A-or-B) as less likely than one of its constituents, the converse of the well-known conjunction fallacy. Through the Linda problem and other examples, it argues that psychological framing (conjunction vs. disjunction) affects how naturally fallacies occur, with implications for understanding intuitive judgment.
A root cause analysis technique that repeatedly asks 'why' to move from a problem to possible underlying causes. Five questions is a guideline, and the answers need evidence.
Taleb argues that the timing and variability of nutrient intake may matter as well as the total consumed. He uses episodic deprivation as an example of a stressor that could change the body’s response; the passage proposes benefits without establishing a dietary regimen.
A Black Swan is a highly improbable event that is unpredictable to the observer but rationalized in hindsight. The concept is relative to the observer's knowledge, and such events can be eliminated through science or open-mindedness, but can also be created by giving false confidence.
Homuncular functionalism explains complex mental tasks by dividing them among simpler subsystems, then dividing those tasks again until basic mechanical operations suffice. The explanation avoids an infinite regress because it ends with operations that need no intelligent inner operator. Dennett proposes a competitive, biologically inspired version of this model.
Shared vision, rooted in common caring, is a powerful force that binds people together and provides focus and energy for generative learning in organizations.
The constant minor complaints of some individuals (Blues) release stress, preventing larger emotional blow-ups, much like a leaking tap on a beer barrel.
Native advertising adopts the appearance of editorial content. Caulfield and Wineburg argue that this can mislead readers about who paid for a message and weaken the separation between journalism and advertising.
People often infer dispositions from behavior even when situational factors fully explain the behavior, a phenomenon known as the fundamental attribution error. The correction model proposes that dispositional inference involves three stages—categorization, characterization, and correction—with correction being the most effortful and frequently overlooked, especially under cognitive load.
Safety is an emergent property of complex adaptive systems, not a product. Leaders often mistakenly see safety as an ordered problem, but using the Cynefin Framework reveals that most safety issues reside in complex or chaotic domains, requiring different approaches.
Dorothy Hamachi-Berry describes using dialogue, inquiry, and shared aspirations in World Bank and IFC teams. She reports that working with clients and developing managers’ own practices helped the approach spread, and she connects it with later collaboration and business results.
Damasio describes homeostasis as regulation that keeps living systems within ranges compatible with survival and flourishing. The excerpt extends this idea by analogy to people and organizations adapting their goals after change, with feelings as one source of feedback.
Erikson compares learning his DISA behavior framework with learning a language: practice matters more than memorizing categories. The analogy supports observing and checking communication preferences; it does not establish that personality guesses become accurate through repetition alone.
This materiality standard uses hypothetical patients with different conditions and values to ask which risk information would change a modeled decision. It helps prioritize communication by examining what an audience needs to know, rather than assuming that every fact matters equally to every person.
This concept uses Monte Carlo simulation as a metaphor to understand the role of randomness in historical sequences, arguing that age often indicates robustness and that historians should better understand sampling theory.
A nonlinear model evaluated at an average parameter can differ from the same model averaged over uncertain parameter values. Taleb uses this difference to examine convexity bias and tail-risk sensitivity. The effect depends on curvature, parameter uncertainty, and the region of outcomes being assessed.
Organizations need a purpose beyond profit to inspire genuine commitment and alignment from employees, enabling them to integrate their personal values with their work.
The model links an extracted resource stock with capital investment and depreciation. The resource has no replenishment inflow, and declining yield constrains extraction and profit.
A renewable resource and the capital used to harvest it form linked stocks. Profits can fund more harvesting capacity even as the resource declines, creating a risk that harvest will exceed regeneration and cause collapse.
Search results depend partly on how a question is phrased. The authors argue that searches which signal a preferred answer can reinforce confirmation bias, and recommend neutral queries followed by evaluation of the sources.
In an interview collected in Thinking: The New Science of Decision, Simone Schnall describes research on whether physical cleanliness, disgust, and other feelings influence moral judgments. She distinguishes the laboratory studies from proposed applications outside the lab.
Taleb argues for a society that can withstand expert errors and failed forecasts. His priority is to contain mistakes so they cannot spread through the system and cause widespread failure.
Tools sometimes find valuable uses their builders did not foresee. Taleb uses the laser, computer, and Internet to argue that curiosity-driven development can contribute to discovery, while noting that many tools accomplish little.
A stock grows when inflow exceeds outflow, shrinks when outflow exceeds inflow, and stays constant when they balance. Population and industrial capital illustrate how reinforcing and balancing feedback loops produce these patterns, and how the pattern changes when the relative strength of the loops changes.
Galef argues that scorn can make persuasion harder by leaving a person’s actual concerns unaddressed. When distrust of an institution is central to a disagreement, citing that institution alone may not resolve it.
Delays in balancing feedback loops can cause oscillations, as in a car dealership’s inventory. When exponential growth is constrained by a nonrenewable resource, the system can instead reach a peak and decline, as in an oil extraction model.
Repeated independent left-or-right steps produce a binomial distribution: middle outcomes can occur in more ways than extreme ones. With many steps and suitable scaling, its shape approaches a Gaussian bell curve.
Taleb illustrates Mediocristan with a rug whose small irregularities disappear at a distance, and Extremistan with mountains that remain jagged across a range of scales. The analogy contrasts fluctuations that average out with extremes that can continue to dominate.
Challenges are normal and help us learn and develop. Focusing on a specific outcome can reduce willingness to experiment, potentially missing better results.
The above average effect (better-than-average effect) is the tendency for individuals to rate themselves as above average on ambiguous traits, but this may reflect accurate self-assessments based on personal definitions rather than unrealistic bias.
In Extremistan, low measured volatility can coexist with large, unexpected jumps. Calm periods can therefore give a misleading impression of safety.
Abstraction allows us to find similarities between different situations by discarding surface details, leading to logical consistency and efficient study. It enables thought experiments and the discovery of deep structures that unify diverse phenomena.
Abstraction is the process of ignoring details to move from real-world situations to an abstract world where logic applies, enabling the discovery of commonalities and analogies between different situations.
Extraction isolates a useful part of a familiar design or idea. Abstraction identifies something less tangible, such as the function it performs. De Bono uses these techniques to loosen fixed assumptions and find other ways to achieve a goal.
A theorem shows that Dawes’ Rule makes perfect inferences in a finite environment containing every possible uncertain but favorable binary cue. This idealized result explains one way abundant information can favor a linear model; ordinary collections of many cues need not meet its conditions.
Abusive ad hominem uses insults or derogatory labels in place of relevant support for rejecting a person’s argument. The question is whether the attack addresses the claim or merely distracts from it.
Taleb argues that academic guilds can protect their own interests at the expense of knowledge. His critique targets tenure and weak competition as potential barriers to correcting errors.
The fallacy of accent occurs when an argument uses a statement under one emphasis or context, then draws a conclusion that depends on a different reading. Vocal stress, punctuation or omitted context can enable the shift. An ambiguous sentence alone is not yet a fallacious argument.
Embracing change and learning to be flexible helps you respond better to life crises and take new directions, a key trait of resilient people.
When mistakes happen, acknowledge your contribution and take responsibility for handling the aftermath rather than letting emotions dictate your response.
The author explains that despite understanding probability and randomness, he cannot fight his emotional reactions and must accept his predisposition to be fooled by randomness, using practical tricks like avoiding eye contact or imagining others as non-human to manage emotional responses.
Recognizing random variation can help separate the quality of a decision from its immediate result. Galef uses a pitcher’s response to good and bad streaks to illustrate a steadier way of evaluating performance.
Attribute substitution is a heuristic where judgments about a target attribute are made by substituting a more accessible attribute, often automatically. This occurs when the target attribute is inaccessible, a related attribute is highly accessible, and the substitution is not overridden by System 2.
Different fields of study use distinct methods to determine and verify truth: science relies on the scientific method, while mathematics uses logic. Misuse of terms like 'logic' and 'mathematically' in arguments often reflects a desire for irrefutable proof but can be misleading.
The fallacy of accident occurs when a general rule that is usually true is applied to a specific case where it does not apply, often due to irrelevant or accidental factors.
The accident fallacy occurs when a general rule is applied to all situations without considering legitimate exceptions, often to preserve simplicity at the cost of rationality.
Accountability is the expectation that one will be called upon to justify one's opinions or conduct to others, serving as a norm-enforcement mechanism that shapes decision-making and behavior.
Accountability, particularly predecisional accountability to audiences with unknown views, can either reduce or amplify cognitive biases depending on the context. Preemptive self-criticism induced by accountability attenuates biases like the fundamental attribution error and overconfidence, but can amplify biases like ambiguity aversion and the dilution effect when it leads to overintegration of irrelevant information.
Accountability means being willing or obliged to explain your beliefs and decisions to others. Duke describes how a group that rewards accuracy can help members question their confidence and follow rules they set before emotions run high.
Accountability mapping tools, such as the RACI model, RAPID model, and swim lane diagrams, clarify roles and responsibilities by visualizing who is accountable and responsible for tasks, revealing confusion and enabling alignment among managers.
Financial accounts, balanced scorecards and performance indicators help organizations track their condition. Their usefulness depends on reliable, relevant data: a dashboard can conceal problems through poor data quality or overwhelm managers with detail.
