Similar to the Halo Effect in reverse, which involves the perception of someone positively based on a single positive trait, the Horn Effect de...

Hofstadter's Law, proposed by cognitive scientist Douglas Hofstadter, states that "It always takes longer than you expect, even when you take into account Hofstadter's Law." This law highlights the tendency for individuals to underestimate the time and effort required to complete tasks, projects, or goals, even when they consciously adjust their estimates to account for potential delays or obstacl...

Hick's Law, also known as Hick-Hyman Law, states that the time it takes for an individual to make a decision increases logarithmically with the number of choices or stimuli presented. In other words, as the number of options increases, the decision-making process becomes more complex and time-consuming, leading to slower response times and potentially poorer decision quality. More options, slower...

Hanlon's Razor is a philosophical principle that advises individuals to avoid attributing malice to actions that can be adequately explained by incompetence, ignorance, or misunderstanding. In other words, when faced with puzzling or frustrating behavior from others, Hanlon's Razor encourages giving the benefit of the doubt and assuming good intentions rather than assuming malicious intent. Never...

Low expectations,...

Generals Fighting the Last War is a mental model that highlights the tendency for individuals or organizations to base their strategies and decisions on past experiences or outdated paradigms, rather than adapting to current or future challenges and opportunities.

The Generalist vs. Specialist mental model refers to the distinction between individuals who possess broad knowledge and skills across multiple domains (generalists) and those who have deep expertise and focus in a specific area (specialists). Generalists excel in synthesizing diverse information, adapting to new contexts, and fostering interdisciplinary connections, while specialists demonstrate...

First-Conclusion Bias, also known as anchoring bias, is a cognitive bias where individuals tend to rely heavily on the first piece of information or initial conclusion they encounter when making decisions, even when subsequent evidence suggests a different conclusion would be more appropriate.

Falsification is a principle proposed by philosopher Karl Popper as a criterion for distinguishing scientific theories from pseudoscience. According to falsification, a scientific theory must be capable of being tested and potentially proven false through empirical observation or experimentation. In other words, scientific hypotheses should make specific, testable predictions that can be either co...

The Dunning-Kruger Effect is a cognitive bias where individuals with low ability or knowledge in a particular domain tend to overestimate their competence and skills, while simultaneously failing to recognize their own incompetence. Conversely, individuals with higher levels of competence may underestimate their abilities relative to others. This phenomenon arises from a lack of metacognitive skil...

Denial involves minimizing, distorting, or outright rejecting evidence or facts that conflict with one's beliefs, values, or self-image, in an attempt to protect oneself from psychological discomfort or cognitive dissonance. It’...

Deliberate practice is a structured and focused approach to skill development that involves engaging in activities specifically designed to improve performance, receive immediate feedback, and refine skills over time.

Conditioning, also known as Pavlovian association or classical conditioning, is a psychological principle that describes the process of learning through repeated associations between stimuli and responses. In classical conditioning, a neutral stimulus (such as a bell) becomes associated with a meaningful or salient stimulus (such as food) through repeated pairings, leading to a conditioned respons...

Commitment/Consistency Bias is a cognitive bias where individuals have a tendency to align their actions, beliefs, and attitudes with previous commitments or statements they have made, even if those commitments are no longer rational or beneficial.

These communities witnessed military personnel building airstrips and receiving airdropped supplies, including valuable cargo. Believing that these actions were responsible for the delivery of goods, some indigenous people began mimicking the rituals and st...

The bystander effect is a social psychological phenomenon where individuals are less likely to intervene in an emergency situation when other people are present. The presence of bystanders can create diffusion of responsibility, where individuals assume that someone else will take action, leading to a delay or failure to assist those in need. Someone else will help, right? Bystander Effect warns h...

The Broken Windows Theory is a criminological theory that suggests that visible signs of disorder, neglect, or minor crimes in a community can lead to an increase in more serious crimes and social decay. The theory posits that if minor issues, such as broken windows, graffiti, or litter, are left unaddressed, it signals to potential offenders that there is a lack of social control and that deviant...

Blind spot bias refers to the tendency for individuals to recognize cognitive biases in others more readily than in themselves. It occurs when people underestimate their susceptibility to biases and overestimate their ability to make rational, objective judgments. This bias can lead individuals to overlook or minimize their own cognitive blind spots, hindering self-awareness, introspection, and cr...

Bias from incentives refers to the phenomenon where individuals' judgments or decisions are influenced by the incentives or rewards they stand to gain or lose.
