Psychological Concepts

​

Anchoring Effect - The tendency to rely too heavily—to "anchor"—on one trait or piece of information when making decisions (usually the first piece of information acquired on that subject)

Cognitive Dissonance - Ignoring evidence that conflicts with one's beliefs

Dunning-Kruger Effect - The tendency for unskilled individuals to overestimate their own ability and the tendency for experts to underestimate their own ability 

Fundamental Error of Attribution - The tendency for people to overemphasize personality-based explanations for behaviors observed in others while under-emphasizing the role and power of situational influences on the same behavior

Gish Gallop - A rhetorical technique in which a person in a debate attempts to overwhelm an opponent by presenting an excessive number of arguments, without regard for their accuracy or strength, with a rapidity that makes it impossible for the opponent to address them in the time available

Groupthink - The psychological phenomenon that occurs within a group of people in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome. Group members try to minimize conflict and reach a consensus decision without critical evaluation of alternative viewpoints by actively suppressing dissenting viewpoints, and by isolating themselves from outside influences.

Sunk Cost Fallacy - The tendency to persist in an endeavor once an investment in money, time, or effort has been made, regardless of future costs.

Technology Adoption Curve - In his book, Crossing the Chasm, Geoffrey A. Moore shows a model that dissects and represents the stages of adoption of high-tech products. The model goes through five stages based on the psychographic features of customers at each stage: innovators, early adopters, early majority, late majority, and laggards.

Unconscious Bias - The underlying attitudes and stereotypes that people unconsciously attribute to another person or group of people that affect how they understand and engage with them
