ONE OF SEVEN WAYS OF SEEING
Make useful decisions when time and information are limited.
Taleb favors practices with long records of survival when short observation periods can hide rare failures. He argues that those proposing to disturb a complex system should bear the burden of proof; longevity is a heuristic rather than proof of safety.
Before clicking a search result, examine the URL, title, and snippet to quickly assess the source's authority and relevance. This practice, called result mining, saves time and improves search efficiency.
Reversal is a creative thinking technique where you reverse a situation or its aspects to generate new perspectives and ideas, even if the reversal seems ridiculous.
A lateral thinking technique that involves deliberately reversing a conventional assumption or viewpoint to escape standard patterns of thought, often leading to new insights or solutions.
A creative thinking exercise where individuals generate alternative perspectives by reversing a given situation in as many ways as possible, then categorizing the types of reversals.
A heuristic that involves deliberately shifting attention to different features of a situation to gain new insights, especially when natural focus may be misleading, by using methods like reversal, listing features, and systematic rotation.
Rules set boundaries for decisions, filters screen alternatives, and checklists help us remember critical steps. Their usefulness depends on evidence, the costs of mistakes, and a clear goal; none removes the need for judgment.
The technique of comparing the output of a mechanical process against real-world constraints. It prevents blind acceptance of absurd results (like -4 grams of water) by forcing a contextual evaluation of the outcome.
After using any analytic structuring technique, perform a sanity check by asking whether the result makes sense. If not, reexamine or redo the analysis.
Satisficing is a decision-making heuristic where individuals accept an available option that is 'good enough' rather than searching for the optimal solution, due to constraints like time and cognitive capacity.
Fast and frugal heuristics compare two options using a limited search for predictive cues. Minimalist and Take the Best are examples of simple rules for deciding which option is likely to score higher on a criterion.
A Google Scholar results page can provide a quick starting point for checking a claim. Look for relevant scholarly work and established institutions, then inspect what those sources actually say.
People sometimes apply statistical reasoning in everyday situations, but their use is selective and often overshadowed by the representativeness heuristic. Examples include intuition about small samples and base rates in causal attributions, as illustrated by anecdotes and experimental findings.
Speakers initially plan utterances egocentrically (anchoring) and then adjust for their audience (adjustment), but this adjustment is often insufficient and can be disrupted by time pressure, revealing a dual-process model of audience design.
Confidence is not solely derived from achievements; it is also cultivated by how you internally frame past hardships. By recalling instances where you persevered through adversity, you reinforce your ability to handle future challenges.
The barbell strategy is a bimodal approach that combines extreme risk aversion in some areas with extreme risk-taking in others, avoiding the middle to achieve antifragility by reducing downside risk and allowing upside from positive Black Swans.
Serious play means making room for curious, low-pressure exploration within work or practice. The Feynman anecdote illustrates how following an interesting question can renew engagement. Play may help with boredom or a creative block, while exhaustion can also require rest or changes to working conditions.
Setting realistic goals and breaking them into manageable steps helps resilient people cope with crisis situations by providing a clear path forward.
Breaking large projects into smaller, manageable steps with a visual timeline helps reduce mental clutter and improve goal achievement, applicable to tasks from professional projects to children's assignments.
SIFT stands for Stop, Investigate the source, Find other coverage, and Trace the claim to its original context. It turns questions about credibility into concrete steps for finding context before assessing a piece of online content.
When encountering information online, first ask 'Do we know what we are looking at?' rather than 'Is this true?' SIFT is a quick heuristic (Stop, Investigate the Source, Find Other Coverage, Trace the Claim to the Original Context) to gain essential context before deeper analysis.
The similarity heuristic leads both animals and humans to equate appearance with reality, forming a cognitive shortcut innate at birth. This tendency is related to generalization in learning and is especially prominent in young children who confuse appearance and reality.
Simple shapes provide recognizable visual metaphors for abstract concepts, helping you understand and remember them.
Taleb argues that designers who bear the consequences of failure have a reason to keep systems simple. People rewarded for appearing sophisticated may instead add complexity whose costs fall on others.
Skin in the game means bearing a personal share of the consequences of your decisions. Taleb uses it as a test of accountability: who receives the gains, who absorbs the losses, and can the decision-maker shift costs onto other people?
Taleb uses Herodotus’s story of a corrupt judge to illustrate personal consequences for abusing authority. The practical question is how decision-makers can be accountable for misconduct and the effects of their choices.
Smart heuristics are simple, fast, and frugal decision-making strategies that ignore information to make good decisions under uncertainty, contrary to the ideal of optimization. They demonstrate that less information can lead to better outcomes in many real-world situations.
People naturally adapt their behavior to one another in social interactions; this heuristic advocates making the right adjustment deliberately from the start to improve communication and outcomes, though it is not always perfect.
The social default is the human tendency to conform to social pressure and make decisions based on others' expectations rather than personal deliberation. A simple safeguard, like a mandatory waiting period before agreeing, can help overcome this bias.
Thaler and Sunstein report that household energy comparisons reduced consumption by about 2% in the research they discuss, comparable to a temporary 11-20% price increase. Including feedback in regular bills kept the intervention inexpensive.
Erikson recommends enjoyable social activities as a way to help people he describes as Yellows recover from stress.
Resilience is developed over time and can be learned by practicing common traits of resilient people, without needing a specific set of actions.
Erikson uses his Green personality category to discuss avoiding decisions and blaming external circumstances. He argues that a hesitant group may need clear, gentle direction and specific responsibility for action.
Distinguish who shared a claim, who reported it, who did the original reporting, and who conducted any underlying research. Each source plays a different role, and the depth of checking should fit what you plan to do with the information.
Taleb warns against invoking Heisenberg’s uncertainty principle as an explanation for limits of prediction in economics or politics. A scientific analogy needs a relevant mechanism; citing quantum physics does not establish one.
When a claim borrows scientific terms, ask what they mean, what evidence supports the claim, and what result could show it is wrong. Technical language can describe a precise idea or disguise a vague one; the wording alone does not decide which.
Musashi advises aiming at the face to provoke a defensive response, then attacking as the opponent moves. The strike may land at the face or elsewhere; the emphasis is on adapting while continuing the attack.
Musashi recommends attacking directly with full resolve so hesitation does not give the opponent an opening. He allows for other approaches when the situation requires them.
Regular physical activity can support clear thinking and brain health. Harrison makes the case for building manageable amounts of movement into daily life and choosing activities you can sustain.
A strategy for leaders to implement organizational innovations without triggering resistance from senior management by carefully managing communication and aligning with corporate values, as exemplified by Dave Marsing's approach at Intel's Fab 11.
In Erikson’s color typology, a Blue is described as preferring specific, factual feedback. He advises stating the performance issue directly, explaining the evidence and discussing improvements rather than burying criticism between unrelated compliments.
This Musashi interpretation urges maintaining pressure during an attack so the opponent cannot recover. It emphasizes coordinated commitment of body and attention; the examples examine where that principle transfers and where continued pressure may be costly.
Before analyzing or sharing information, first verify the source's identity and credibility. A failure to do so led a New York Times columnist to cite a known fake antifa Twitter account as evidence of left-wing attacks.
Establish personal rules to create rituals that harness the same inertia that normally trips us up, turning stubbornness into a tool for positive change.
In Erikson’s color model, Yellows and Reds prefer variety and flexibility to routine tasks and tightly packed schedules.
Sturgeon’s Law says that most work in any field is mediocre. Dennett draws a rule for fair criticism from this deliberately sweeping maxim: address a field’s strongest examples rather than treating its worst work as representative.
When faced with a difficult question, people often unconsciously substitute an easier related question and answer that instead. This heuristic can provide quick, adequate answers but sometimes leads to systematic errors.
Having a support system of friends, family, colleagues, or online groups can help you express emotions, gain new perspectives, and find solutions to problems.
Taleb argues that, when a profession reliably tests performance, sustained success despite an unpolished appearance can reveal ability that credentials and presentation miss. His heuristic depends on that selection process; looking unlike an expert is not itself evidence of competence.
To make a logical, unemotional person (a 'Blue') uncomfortable and avoid you, expose them to overly emotional people, as they find sentimentality unpleasant.
Suspended judgement is a key principle in brainstorming where no evaluation of ideas is allowed during the session. It encourages free expression of ideas without fear of criticism, allowing even seemingly ridiculous suggestions to be put forward.
In sympathetic magical thinking, contagion treats contact as transferring an enduring essence, while similarity treats resemblance as evidence of shared properties or powers. These beliefs can shape feelings about objects even when no physical effect is established.
Dual-process accounts distinguish fast, automatic, intuitive System 1 from slow, deliberate, analytical System 2. Taleb argues that reasoning errors often arise when we believe we are using System 2 while relying on System 1.
Before evaluating an unfamiliar claim in detail, get an overview from sources that summarize the relevant research. Compare their expertise, evidence, dates, and degree of agreement. That context helps you judge what a single paper adds and where uncertainty remains.
Stress can make it easy to neglect sleep, exercise, and other needs. Making time for rest and activities you enjoy can help you cope.
Focus on one task at a time to avoid overwhelm and increase clarity, enabling purposeful progress toward goals.
Take the Best is a fast and frugal heuristic that searches for cues in order of their validity and makes a decision based on the first discriminating cue, rather than integrating all information. It is similar to Minimalist but uses the highest-validity cue first.
Take the Best compares two options by checking cues in order of their predictive validity. It stops at the first cue that distinguishes them and predicts from that cue alone. In the studies summarized here, it required far fewer computations than regression and remained competitive when tested on held-out data.
Under the source’s definition, information is scarce when the number of binary cues is less than log2(N). Its theorem says Take the Best is more accurate than Dawes’ Rule when averaged across the specified possible environments, not necessarily in any particular environment.
Erikson advises keeping discussions factual and focused on work with people he describes as Blues. His example emphasizes respecting privacy and allowing personal conversation to develop at the other person’s pace.
