concept

a mental grouping of similar objects, events, ideas or people.

prototype

a mental image or best example of a category. matching new items to a prototype provides a quick and easy method for sorting items into categories (as when comparing feathered creatures to a prototypical bird, such as a robin)

intuition

an effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning.

belief perseverance

clinging to one's initial conceptions after the basis on which they were formed has been discredited.

availability heuristic

estimating the likelihood of events based on their availability in memory; if instances come readily to mind (perhaps bc of their vividness), we presume such events are common

overconfidence

the tendency to be more confident than correct - to overestimate the accuracy of our beliefs and judgments

framing

the way an issue is posed; how an issue is framed can significantly affect decisions and judgments.

algorithm

a methodical, logical rule or procedure that guarantees solving a particular problem. contrasts w/ the usually speedier -- but also error prone use of heuristics

heuristic

a simple thinking strategy that often allows us to make judgments and solve problems efficiently; usually speedier but also more error-prone than algorithms.

insight

a sudden realization of a problem's solution; contrasts w/ strategy based solutions

fixation (mental set)

a tendency ti approach a problem in one particular way, often a way that has been successful in the past.

confirmation bias

a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence
