Optimism bias is typically measured through two determinants of risk: absolute risk, where individuals are asked to estimate their likelihood of experiencing a negative event compared to their actual chance of experiencing a negative event (comparison against self), and comparative risk, where individuals are asked to estimate the likelihood of experiencing a negative event (their personal ...
Groupshift, the tendency for decisions to be more risk-seeking or risk-averse than the group as a whole, if the group is already biased in that direction; Social desirability bias, the tendency to over-report socially desirable characteristics or behaviours in oneself and under-report socially undesirable characteristics or behaviours.

There are more than 80 tools available to assess the quality and risk of bias in observational studies reflecting the diversity of research approaches between fields. [36] [37] [38] These tools usually include an assessment of how dependent variables were measured, appropriate selection of participants, and appropriate control for confounding ...
The framing effect is a cognitive bias in which people decide between options based on whether the options are presented with positive or negative connotations. [1] Individuals have a tendency to make risk-avoidant choices when options are positively framed, while selecting more loss-avoidant options when presented with a negative frame.
Detection bias occurs when a phenomenon is more likely to be observed for a particular set of study subjects. For instance, the syndemic involving obesity and diabetes may mean doctors are more likely to look for diabetes in obese patients than in thinner patients, leading to an inflation in diabetes among obese patients because of skewed detection efforts.
The negativity bias is noticeable in a plethora of situations related to the formation of risk-averse behaviour. Notably, any stimuli that evokes the expression of fear encourages risk -aversion. The human brain has adapted to easily parse out these stimuli from a sea of benign stimuli.
Confirmation bias (also confirmatory bias, myside bias, [a] or congeniality bias [2]) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. [3]
