A growing collection of ideas for understanding the world — and your own thinking.
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.
Critique of schools that teach flashy techniques; emphasizes the true Way of the warrior, which is direct, disciplined, and devoted to killing with one stroke.
Schools that rely on the extra long sword and distance become weak because they avoid closing in. True strategy requires closing in and defeating the enemy with one stroke, relying on spirit and resolve rather than weapon length.
Nisbett argues that cultural assumptions influence scientists’ questions and interpretations. His historical examples challenge a picture of science as reasoning untouched by social context.
An unusual association or dream can suggest a scientific hypothesis. The author uses scientists’ unconventional interests to illustrate that inspiration can come from unexpected places; a hypothesis still needs evidence and testing.
Unconventional questions and unexpected associations can suggest research ideas. The historical anecdotes in this passage illustrate the range of scientists’ interests; those interests do not establish the truth of their occult beliefs or of an untested hypothesis.
Science relies on imagination, metaphor, and analogy to describe unknown phenomena, using models that approximate reality but must not be confused with it. Richard Feynman's chess analogy illustrates how scientists infer rules from observations, recognizing that unexpected discoveries can lead to deeper understanding.
A scientific explanation can be short and engaging while preserving its central claim. Cheng argues that communicators should learn from memes’ appeal without letting a catchy phrase misstate the evidence or erase uncertainty.
Harrison urges readers to judge science and superstition by their results. Science can be misused or mistaken, but its methods allow claims to be tested and corrected.
Taylor’s scientific management divides work into specialized tasks and uses measurement and incentives to improve efficiency. Its limits include changing conditions, strategic responses to incentives, and motivations beyond pay.
Scientific inquiry tests explanations against observations and experiments. Clear methods, accessible evidence, and the possibility of results that challenge a hypothesis help others assess and repeat the work.
Thinking like a scientist means treating a strategy as a hypothesis, testing it, and revising it when the evidence changes. Adam Grant describes an experiment in which startup founders trained this way earned more revenue and changed direction more often than a control group.
Scientific theories are evidence-based and probabilistic; mathematical theories are logically proven and certain. Misunderstanding this distinction leads to flawed arguments and conspiracy thinking.
Scope neglect occurs when willingness to pay changes little despite a large change in the amount of a public good. The authors propose that people may respond to an emotionally vivid example rather than fully account for the scale of the benefit.
A scout mindset seeks truth and accuracy, even when uncomfortable, by investigating evidence open-mindedly rather than defending a predetermined belief.
Scout mindset is a way of reasoning focused on accuracy and truth-seeking, like a scout making a map, rather than defending pre-existing beliefs. It helps individuals avoid self-deception and make better judgments in tough personal and professional decisions.
Charlie Munger and Warren Buffett advocate for a culture of trust over excessive process and compliance, believing that hiring and dealing only with trustworthy individuals leads to greater efficiency and success. They emphasize that trust must be earned and that it's essential to avoid people of questionable reputation.
Taleb argues that the benefit of an intervention may rise sharply with the severity of a condition. If treatment harms stayed roughly constant, the balance of benefit and harm would change with baseline risk. These are assumptions to examine for a particular treatment, not a general rule to treat only severe illness.
Rapidly accelerating knowledge makes it crucial to question our beliefs and think like scientists. Preacher, prosecutor, and politician modes of thinking differ from the more open, evidence-based scientist mode. The story of a Madoff investment illustrates the dangers of not having second thoughts.
Second-level thinking involves considering the long-term consequences of decisions by asking 'And then what?' to avoid creating future problems while solving immediate ones.
Always ask 'And then what?' to trace secondary and long-term consequences of actions, considering the whole system and net benefits over time. Avoid focusing only on immediate, visible effects.
A decision-making approach that evaluates the consequences of consequences, mapping out both positive and negative ripple effects to uncover hidden risks, opportunities, and information needs.
Second-order thinking asks what follows from an action’s immediate effects, including how other people may respond. It helps compare trade-offs and unintended consequences without assuming that a desirable eventual outcome was foreseeable.
Humans automatically seek causal explanations for events, often attributing intentions to agents, which can lead to errors in statistical reasoning. This automatic search for causality is a function of System 1 and can produce coherence even from contradictory evidence.
Systems thinking looks for feedback: actions change conditions, which in turn influence later actions. Senge uses filling a glass of water to show how a seemingly simple action involves a continuing loop of observation and adjustment.
Leaders often recognize a missing organizational capacity, such as collective leadership, and create interventions like 'salons' to foster open conversation and build that capacity, even without controlling outcomes.
The concept emphasizes recognizing the interdependencies between our actions and external forces, using a child's discovery of control over his body as a metaphor for personal growth. It argues that we often stop 'closing the loops' early in life, and that expanding awareness of our connectedness is a key to learning and personal mastery.
Embracing Root Cause Analysis (RCA) with a systems thinking overlay requires a mindset change and is a long-term journey for audit teams, often taking months to years. This approach helps auditors understand recurring problems and provides richer insights for senior management.
Systems citizenship begins with recognizing the interdependencies and patterns we have created, which in turn shape us. By seeing these larger patterns and our own role in them, we can discover new alternatives and change undesirable outcomes.
A systems thinking model for understanding global climate change, emphasizing the feedback loops and delays between CO2 emissions, atmospheric concentration, and temperature, and the need to see beyond immediate economic activity.
System behavior is highly sensitive to feedback loop goals. Inaccurately defined goals can cause the system to efficiently produce an unintended or unwanted result.
Overreliance on expert forecasts despite evidence that they are no more accurate than those of nonexperts.
Guidance on choosing root cause analysis techniques from simple (e.g., three-way five whys) to advanced systems approaches (e.g., STAMP), emphasizing that no single method is best and each has limitations and trade-offs.
Compare possible solutions by weighing advantages and disadvantages, assessing them against a priority, or using SWOT. Define the goal clearly enough to judge whether the chosen solution addresses it.
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.
Selective attention lets us focus on part of the information around us, but it can also make us miss something relevant. In an argument, overlooking a qualification or contrary evidence can distort what we think the other person said.
Ambiguous traits leave room to choose flattering evidence about yourself. The studies described here examine how that freedom changes when people must use specified criteria, including evidence for negative traits.
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.
In the reported experiment, participants were about equally confident in predictions of themselves and others, but more accurate about themselves. The authors explain this through the distinction between an impression's strength and the amount or reliability of evidence supporting it. They also describe cases where self-predictions are underconfident or overconfident.
Self-accountability means examining your own decisions and actions when assessing an outcome. It counters the habit of taking credit for success while attributing failure entirely to circumstances.
When making judgments under uncertainty, people often anchor on initial values (even irrelevant ones) and then insufficiently adjust, resulting in biased judgments. This cognitive bias also applies to language use, where interlocutors anchor on their own perspective and inadequately adjust to their partner's viewpoint.
A cognitive bias where speakers anchor on their own knowledge and perspective, failing to adequately adjust to the listener's perspective, leading to miscommunication.
In the reported experiments, listeners sometimes first considered what they could see or were privately thinking about, then adjusted to what the speaker could know. This egocentric interference occurred even when participants knew that their perspectives differed.
Self-confidence is trusting in your own abilities and value to others. It enables independent thinking, resilience against negative feedback, and adaptability in the face of change.
Self-control is the ability to manage your emotions and impulses, creating space for reason to guide your actions rather than being driven by immediate feelings.
People anticipate their self-control failures and use external aids—like list-making, commitment devices, and social pressure—to align their long-term plans with short-term actions, as illustrated by the Planner-Doer conflict in behavioral economics.
Self-deception and denial are cognitive biases that lead individuals to distort or ignore reality to protect self-interest, maintain comfort, or avoid unpleasant truths, often resulting in wishful thinking and poor decision-making.
People often infer their own traits and characteristics from their current moods and behaviors, especially under time pressure or cognitive load, leading to biased self-perceptions that fail to account for situational factors.
This study varied how many criteria students could use when rating their abilities relative to peers. It examined whether vague traits leave more room for flattering self-assessments than traits evaluated against specified criteria.
The tendency to share disproportionately more accomplishments than failures, leading to skewed perceptions and poor self-assessment.
We often use motivated reasoning to protect our ego, constructing flattering narratives for unflattering facts. This can manifest as self-enhancement (boosting ego) or self-protection (avoiding blows to ego), even leading to 'masochistic epistemology' where we assume the worst because it feels safer.
Self-examination means reviewing experiences, decisions, and reactions to identify what to repeat or change. It can help turn a past event into a specific adjustment in how you act.
People are biased by their own self-interest and incentives, often acting in ways that serve their personal gain even if it conflicts with truth or broader goals. Understanding the incentives of others is crucial for evaluating their advice and actions.
Understanding your own strengths, weaknesses, capabilities, limitations, and especially the boundaries of your knowledge—including unknown unknowns—so you can operate effectively within your circle of competence.
De Bono models memory as a surface changed by incoming information, with earlier changes shaping later patterns. Rain carving channels and hot water sculpting jelly illustrate this self-organization; they are analogies for how the order of experience can matter.
Munger argues that dwelling on misfortune can make it harder to respond to a setback. He favors acknowledging what happened and putting effort into competent, graceful coping.
Specialization and generalization offer different tradeoffs. A narrow niche can reward specific capabilities, while a broader range of resources or skills may provide more options when conditions change. Neither strategy is universally safer.
A self-sealing argument admits no possible counterevidence, so it cannot be falsified. This makes it vacuous as an argument.
The self-serving bias is the tendency to take credit for positive outcomes (attributing them to skill) and blame negative outcomes on external factors like luck, which impairs learning from experience.
In the reported study, participants rated themselves above average on desirable traits and below average on undesirable traits. Self-enhancement was stronger for more ambiguous traits.
