[6] Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise, [5] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both ...
[5] Essentially, after a choice is made people tend to adjust their attitudes to be consistent with, the decision they have already made. [6] [2] [7] It is also possible that choice-supportive memories arise because an individual is only paying attention to certain pieces of information when making a decision or to post-choice cognitive ...
Biases usually affect decision-making processes. They appear more when decision task has time pressure, is done under high stress and/or task is highly complex. [68] Here is a list of commonly debated biases in judgment and decision-making:
Biases specific to groups (such as the risky shift) versus biases at the individual level. Biases that affect decision-making, where the desirability of options has to be considered (e.g., sunk costs fallacy). Biases, such as illusory correlation, that affect judgment of how likely something is or whether one thing is the cause of another.
The neglect of probability, a type of cognitive bias, is the tendency to disregard probability when making a decision under uncertainty and is one simple way in which people regularly violate the normative rules for decision making. Small risks are typically either neglected entirely or hugely overrated.
The framing effect has consistently been shown to be one of the largest biases in decision making. [11] In general, susceptibility to framing effects increases with age. Age difference factors are particularly important when considering health care [ 12 ] [ 13 ] [ 14 ] and financial decisions.
Loss aversion is part of prospect theory, a cornerstone in behavioral economics. The theory explored numerous behavioral biases leading to sub-optimal decisions making. [5] Kahneman and Tversky found that people are biased in their real estimation of probability of events happening.
While similar to the hindsight bias, the two phenomena are markedly different. Hindsight bias focuses on memory distortion to favor the actor, while the outcome bias focuses exclusively on weighting the outcome heavier than other pieces of information in deciding if a past decision was correct.
