Commitment Devices

A commitment device makes a future choice harder to reverse or attaches a cost to abandoning a goal. People use it to help a long-term plan survive later temptation.

Commitment to the Truth

Commitment to the truth means noticing self-deception, questioning our explanations, and examining the patterns behind recurring problems. Senge presents it as part of personal mastery: seeing our own role in a situation can reveal choices we had overlooked.

Compellingness

Compellingness is the feeling that something is interesting, relevant, authoritative, or timely enough to deserve attention. The authors use early story-understanding research to explain how such feelings help select what to investigate; they do not establish whether a claim is true.

Compensating Feedback

Compensating feedback is a systems thinking phenomenon where well-intentioned interventions trigger responses that counteract the intended benefits, often leading to worsening conditions. It describes the experience of pushing harder only to find the system pushing back more.

Competence Without Comprehension

Competence can arise without comprehension, as exemplified by natural selection's ability to design complex organisms without any understanding, contrasting with human learning where comprehension is typically the key to competence.

Competitive Advantage in the Sexual Market Place

Cost leadership, differentiation, market scope, and core competence explain ways businesses compete. A dating analogy applies these concepts to personal traits, social circles, and niche interests. Its claims about attraction depend on assumptions about people’s preferences that the business concepts alone cannot establish.

Complaining Is Not a Solution

Repeated complaints can substitute for examining a problem and deciding what to do. Parrish urges readers to identify actions within their control, including their own contribution to a situation.

Complex Adaptive Systems

Complex adaptive systems contain interacting agents that change their behavior in response to experience and to one another. Their collective patterns depend on those interactions, so studying each part separately is not enough to explain the whole.

Complexity

Complexity thinking asks risk managers to consider feedback, interdependence and change when choosing controls. The Cynefin approach emphasizes adapting to the kind of system involved and creating conditions in which useful responses can emerge.

Compound Interest

Compound interest is the process where interest earned is added to the principal, generating further interest and leading to exponential growth over time. It applies to finance as well as relationships, habits, learning, and fitness.

economics · psychology↗

Compounding

Compounding adds returns to a base so that later returns apply to the accumulated amount. A constant positive percentage rate produces exponential growth. Learning and relationships offer useful analogies when earlier gains make later gains possible, but their growth does not follow a fixed interest formula.

Mental Modelsintermediate

Compounding Relationships

Relationships can create opportunities for further relationships. Preferential attachment models one version of this feedback: a well-connected node is more likely to attract new links. Sidney Weinberg’s career illustrates how introductions, trust, and reciprocal help can accumulate, while also showing the importance of an initial opportunity.

Compounding Uncertainty (Fukushima)

Taleb argues that uncertainty about model parameters, including uncertainty about the errors themselves, can make extreme events more likely than a fixed-parameter model suggests. He illustrates the concern with a claimed shift in Fukushima recurrence estimates from a million years to 30 years; the derivation is not supplied.

Computational Kindness

Computational kindness means making a task easier for the person who must do it. State your preferences, offer a few concrete meeting times, or design a queue that lets people stop watching for an opening. These choices reduce the work of searching, guessing, and repeatedly checking.

Mental Modelsintermediate

Conditionally Dependent Probabilities

For a sequence of events, multiply the probability of the first by each subsequent event’s probability conditional on earlier successes. The conditional estimates need a stated basis; the mere fact that tasks occur in order does not determine them.

Conditions for Valid Intuition: The Environment of Skill

Intuitive judgments are only trustworthy when developed in environments with stable regularities and sufficient opportunities for practice. Subjective confidence is not a reliable indicator of accuracy, and intuitions can be misleading in unpredictable or 'wicked' environments.

Condorcet Paradox

The Condorcet paradox occurs when collective preferences become cyclic, meaning that no candidate is the majority-preferred choice in all head-to-head matchups despite individual transitive preferences, challenging the notion of a clear 'people's choice' in voting systems.

Confident Humility

Confident humility is the ability to have faith in your capability while appreciating that you may not have the right solution or even be addressing the right problem, allowing for reexamination of old knowledge and pursuit of new insights.

Conflict Between System 1 and System 2

A classic experiment illustrating conflict between automatic (System 1) and controlled (System 2) processes, where automatic responses interfere with intended tasks, and System 2 exerts self-control to override them.

Conflict of Interest

A conflict of interest exists when a source has interests that could compromise its judgment or impartiality. The authors use fossil-fuel advertising to show why incentives matter when checking a claim.

Confronting Prejudice Through Dialogue and Rethinking

Daryl Davis, a Black musician, engages with KKK members not by preaching but by planting seeds of doubt and finding common ground, leading many to leave the Klan. He emphasizes that those with more power need to do more rethinking and that conversation can change minds when people are given reason to question their own beliefs.

Confusing the Enemy

Confusing the enemy involves using feints and misdirection to force the opponent to constantly redirect their efforts, creating an opening for a decisive strike. It emphasizes controlling the enemy's thoughts and actions to achieve victory.

Consequences of Rare Events (Tail Risk)

Taleb argues that estimating the contribution of a rare event requires considering its size as well as its probability. In domains where a few extreme outcomes dominate, uncertainty about the tail can make the resulting risk estimate highly sensitive to model error.

Consider the Opposite

A technique to counteract confirmation bias by actively considering the opposite of one's initial assumptions, using methods like devil's advocate, disconfirming questions, and deliberate mistakes.

Consistent Evidence

Jones distinguishes testing a hypothesis against contrary evidence from presenting evidence in its favor. Both matter: an explanation should address alternatives and show why the supporting evidence is informative.

Conspiracy Theories

Conspiracy claims can appeal through dramatic stories, apparent patterns, and explanations that seem large enough to match a major event. Harrison argues for examining evidence carefully while recognizing that real conspiracies do occur.

Constraints: Helpful or Harmful?

A constraint can limit output while also helping organize a system. The Theory of Constraints focuses on managing what limits progress toward a goal; Cynefin distinguishes fixed, governing, enabling, and ineffective constraints in different contexts.

Constructive Nature of Perception

Perception combines sensory information with context, expectations, and learned patterns. This usually helps us interpret the world, but it can also produce convincing errors, including pareidolia and visual illusions. Independent observations and controlled comparisons help distinguish an experience from the explanation we give it.

Constructive Optimism

Harrison argues for skepticism that challenges unsupported beliefs while respecting the people who hold them. His constructive optimism combines hope for more rational thinking with recognition that changing beliefs can threaten friendships, family ties, and a sense of belonging.

Constructivism

Constructivism is a learning theory and epistemological stance asserting that knowledge is actively built by the learner through experience and reflection, not passively received. Our understanding of reality is a mental construction, shaped by prior knowledge and interpretation.

Contextual Influences

Social roles, expectations, framing, and other circumstances can shape behavior and judgment. When explaining someone’s actions, consider those conditions alongside their personal traits and the part played by chance.

Contrapositive

The contrapositive of an implication 'If A then B' is 'If not B then not A', which is logically equivalent to the original. Understanding contrapositive helps reframe arguments equivalently and avoids confusion with the converse or negation.

Contrast as Context

A comparison gives a number or image context. Choose contrasts that answer the reader’s question, such as changes over time, differences between regions, or performance against a relevant benchmark.

Convergence and Divergence

Convergent thinking narrows focus to a single solution, while divergent thinking broadens perspective to generate alternatives. Both modes are essential for effective problem solving, but divergence requires deliberate practice.

Convergent Thinking

Convergent thinking is a problem-solving technique where diverse individuals converge on a single, optimal solution to a well-defined question, emphasizing speed and logic over creativity.

Convex Exposure (Likes Volatility)

A payoff is convex over a range when the gain from an upward move outweighs the loss from an equally sized downward move. Within that range, a spread of outcomes around the same mean can increase expected payoff. The range, price paid, and possible losses still matter.

philosophy · economics↗
Mental Modelsintermediate

Convexity and Concavity

For a convex payoff over a specified range, equal upward and downward changes can yield more gain than loss; a concave payoff has the reverse pattern. Taleb connects these responses to antifragility and fragility. The variable, range and direction of benefit matter when applying the idea.

science · mathematics↗
Mental Modelsintermediate

Convexity Effects (Nonlinear Response)

A convex cost rises at an increasing rate as its input increases. Taleb uses congestion to show why fluctuations can matter: periods above capacity may add more delay than quiet periods remove, so average demand alone can mislead.

Convexity Effects in Fragile Systems

Small modifications in an overoptimized system can produce compounded, nonlinear effects that drastically amplify negative outcomes, as illustrated by New York City officials underestimating the traffic impact of a bridge closure.
