cognitive

---

The tendency to rely heavily on the first piece of information encountered (the "anchor") when making decisions or estimates — subsequent judgments adjust from the anchor but rarely far enough.

Origin: Amos Tversky & Daniel Kahneman, 1974

judgment numbers negotiation estimation first-impression

Related: Availability Heuristic, Loss Aversion

cognitive

---

Judging the likelihood of an event based on how easily an example comes to mind — rather than actual statistical frequency.

Origin: Amos Tversky & Daniel Kahneman, 1973

memory probability risk judgment shortcut

Related: Confirmation Bias, Loss Aversion

cognitive

---

The mental discomfort experienced when holding two contradictory beliefs, values, or behaviors simultaneously — driving the mind to resolve the tension by changing one of them.

Origin: Leon Festinger, 1957

belief conflict rationalization motivation consistency

Related: Confirmation Bias, Metacognition

cognitive

---

People with low competence in a domain overestimate their ability, while highly competent people underestimate theirs — because the skills needed to evaluate performance are the same skills required to perform.

Origin: David Dunning & Justin Kruger, 1999

competence confidence metacognition learning self-assessment

Related: Confirmation Bias, Imposter Syndrome, Metacognition

cognitive

---

The halo effect occurs when one positive trait or impression causes people to assume unrelated positive qualities, distorting overall judgment.

Origin: Edward Thorndike, 1920

Thinking about one's own thinking — the ability to monitor, evaluate, and regulate cognitive processes, leading to more accurate self-assessment and better learning outcomes.

Origin: John Flavell, 1976

self-awareness learning thinking regulation accuracy

Related: Dunning-Kruger Effect, Imposter Syndrome, Confirmation Bias

Behavioral (6)

Habits, conditioning, reinforcement, motivation, and learned behavior.

Open category page

behavioral

---

Classical conditioning is learning by association, where a previously neutral cue comes to trigger a response after repeated pairing with a meaningful stimulus.

Origin: Ivan Pavlov, 1897

Related: Operant Conditioning, Habit Loop, Emotional Contagion

behavioral

---

Habits are formed and maintained through a three-part neurological loop: cue → routine → reward — and can be changed by keeping the cue and reward while swapping the routine.
