PsychologyThe Law of the Instrument (Maslow's Hammer)
The cognitive bias of over-relying on a familiar tool or skill, even when it is not the most appropriate for the task at hand. The model is a powerful reminder that if all you have is a hammer, every problem starts to look like a nail. It is the core of strategic humility and a foundational principle of all good problem-solving.
PsychologyThe Bystander Effect
A social psychological phenomenon where individuals are less likely to offer help to a victim when other people are present. It is a powerful reminder that personal responsibility, in some situations, can be diffused across a group, leading to a catastrophic, collective failure.
PsychologyComplexity Science
8 modelsRegression to the Mean
The statistical phenomenon that an extreme event or outcome is likely to be followed by a more average one. This model is a powerful reminder that extreme performance, both good and bad, is rarely sustainable and that the most likely outcome is a return to the average.
Mathematics & StatisticsThe Normal Distribution
A bell-shaped probability distribution that is symmetrical around its mean. This model is a powerful reminder that many of the world's most complex phenomena—from human height to test scores—cluster around a central, average value. It reveals that the extremes are rare and that the most likely outcome is a return to the average.
Mathematics & StatisticsBayesian Thinking
A statistical approach to decision-making that involves updating your beliefs about the world in light of new evidence. This model is a powerful antidote to a rigid, dogmatic mindset, revealing that the path to truth is in a constant, ruthless updating of your beliefs.
Mathematics & StatisticsThe Law of Large Numbers
The principle that as the number of trials of a random event increases, the actual ratio of outcomes will converge on the theoretical or expected ratio. It is a powerful reminder that randomness is only truly visible over a large number of trials and that small, short-term samples can be misleading.
Mathematics & StatisticsThe Bell Curve
A bell-shaped probability distribution that is symmetrical around its mean. This model is a powerful reminder that many of the world's most complex phenomena—from human height to test scores—cluster around a central, average value. It reveals that the extremes are rare and that the most likely outcome is a return to the average.
Mathematics & StatisticsAlgorithmic Thinking
The art of breaking down a complex problem into a series of small, discrete, and unambiguous steps that a computer could follow. This model is a powerful and elegant way of thinking that is not just for programmers but for anyone who wants to solve a problem with clarity and precision.
Computer ScienceMetcalfe's Law
The principle that the value of a telecommunications network is proportional to the square of the number of connected users. This model is a powerful reminder that some systems—like social networks, marketplaces, and ecosystems—gain value from the number of people who use them.
Computer ScienceGarbage Collection
An automated process in computer science that identifies and reclaims memory that is no longer being used by a program. This model is a powerful reminder that every system, from a computer to a company, must have a deliberate and automatic process for removing waste and inefficiency. It is the core of strategic minimalism and a foundational principle of all effective design.
Computer ScienceInformation Theory
4 modelsCounterpoint
The art of combining two or more independent melodic lines in a harmonious and aesthetically pleasing way. This model is a powerful and elegant reminder that a system's true beauty and strength lie not in a single, dominant voice but in the harmonious interplay of multiple, independent parts.
Musical TheoryThe Rule of the Octave
A fundamental principle of musical harmony that states that every note in a melody has a set of harmonious chords that can be played with it. This model is a powerful reminder that every action has a set of predictable consequences, and that the path to a good outcome is in a ruthless pursuit of harmonious, predictable actions.
Musical TheoryThe Sapir-Whorf Hypothesis
The principle that the structure of a person's language can influence their perception of the world. This model is a profound reminder that our reality is not a fixed, objective state but a dynamic, malleable construct shaped by the language we use to describe it.
Linguistics & CommunicationPragmatics
The study of how context influences meaning. This model is a profound reminder that a word's meaning is not a fixed, objective state but a dynamic, malleable construct shaped by the context in which it is used. It is the core of all effective communication and a foundational principle of all strategic thinking.
Linguistics & CommunicationGame Theory
2 modelsThe Prisoner's Dilemma
A foundational concept in game theory that illustrates why two rational individuals might not cooperate, even if it is in their best interest to do so. It is a powerful reminder that self-interest, in some situations, can lead to a suboptimal outcome for everyone involved.
Game TheoryNash Equilibrium
A state of a game where no player has an incentive to unilaterally change their strategy. It is the point where all players are playing their best possible strategy, given the strategies of all other players. It is the core of strategic analysis and a foundational principle of all competitive advantage.
