==Description==
'''Bias''' is an inclination to present or hold a partial [[perspective]] at the expense of (possibly equally valid) alternatives. Bias can come in many forms.

A ''cognitive bias'' is the human [[tendency]] to make systematic [[decisions]] in certain circumstances based on [[cognitive]] factors rather than [[evidence]]. Such biases can result from [[information]]-processing shortcuts called [http://en.wikipedia.org/wiki/Heuristics heuristics]. They include [[errors]] in [[judgment]], social attribution, and [[memory]]. Cognitive biases are a common outcome of human [[thought]], and often drastically skew the reliability of anecdotal and [[legal]] [[evidence]]. It is a [[phenomenon]] studied in [http://en.wikipedia.org/wiki/Cognitive_science cognitive science] and [http://en.wikipedia.org/wiki/Social_psychology social psychology].
