Heuristics are simple for the brain to compute but sometimes introduce "severe and systematic errors." [6] For example, the representativeness heuristic is defined as "The tendency to judge the frequency or likelihood" of an occurrence by the extent of which the event "resembles the typical case." [13]
Since this is a biased estimate of the variance of the unobserved errors, the bias is removed by dividing the sum of the squared residuals by df = n − p − 1, instead of n, where df is the number of degrees of freedom (n minus the number of parameters (excluding the intercept) p being estimated - 1). This forms an unbiased estimate of the ...

Recall bias is a type of measurement bias, and can be a methodological issue in research involving interviews or questionnaires.In this case, it could lead to misclassification of various types of exposure. [2]
Research on attribution biases is founded in attribution theory, which was proposed to explain why and how people create meaning about others' and their own behavior.This theory focuses on identifying how an observer uses information in his/her social environment in order to create a causal explanation for events.
A significant distinction is generally made between errors (systematic deviations) and mistakes (speech performance errors) which are not treated the same from a linguistic viewpoint. The study of learners' errors has been the main area of investigation by linguists in the history of second-language acquisition research.
Unbiased rendering in computer graphics refers to techniques that avoid systematic errors, or biases, in the radiance approximation of an image. This term specifically relates to statistical bias, not subjective bias. Unbiased rendering aims to replicate real-world lighting and shading as accurately as possible without shortcuts.
