mind the gap

From: Laputan Logic























"A cognitive bias is a pattern of poor judgment, often triggered by a particular situation. Identifying 'poor judgment,' or more precisely, a 'deviation in judgment,' requires a standard for comparison, i.e. 'good judgment.' In scientific investigations of cognitive bias, the source of 'good judgment' is that of people outside the situation hypothesized to cause the poor judgment, or, if possible, a set of independently verifiable facts. The existence of most of the particular cognitive biases listed below has been verified empirically in psychology experiments. [...]

Anchoring – the common human tendency to rely too heavily, or 'anchor, on one trait or piece of information when making decisions.
Attentional Bias – implicit cognitive bias defined as the tendency of emotionally dominant stimuli in one's environment to preferentially draw and hold attention.
Backfire effect - Evidence disconfirming our beliefs only strengthens them.
Bandwagon effect – the tendency to do (or believe) things because many other people do (or believe) the same. Related to groupthink and herd behavior.
Bias blind spot – the tendency to see oneself as less biased than other people.
Choice-supportive bias – the tendency to remember one's choices as better than they actually were.
Confirmation bias – the tendency to search for or interpret information in a way that confirms one's preconceptions.
Congruence bias – the tendency to test hypotheses exclusively through direct testing, in contrast to tests of possible alternative hypotheses.
Contrast effect – the enhancement or diminishing of a weight or other measurement when compared with a recently observed contrasting object.
Denomination effect – the tendency to spend more money when it is denominated in small amounts (e.g. coins) rather than large amounts (e.g. bills).
Distinction bias – the tendency to view two options as more dissimilar when evaluating them simultaneously than when evaluating them separately.
Empathy gap - the tendency to underestimate the influence or strength of feelings, in either oneself or others.
Endowment effect – 'the fact that people often demand much more to give up an object than they would be willing to pay to acquire it.'
Experimenter's or Expectation bias – the tendency for experimenters to believe, certify, and publish data that agree with their expectations for the outcome of an experiment, and to disbelieve, discard, or downgrade the corresponding weightings for data that appear to conflict with those expectations.
Focusing effect – the tendency to place too much importance on one aspect of an event; causes error in accurately predicting the utility of a future outcome.
Framing effect – drawing different conclusions from the same information, depending on how that information is presented. [...]"
