Cross-race effect
tendency to more easily recognize faces of the race that one is most familiar with (usually one's own race)
The cross-race effect (sometimes called cross-race bias, other-race bias, own-race bias or other-race effect) is the tendency to more easily recognize faces that belong to one's own racial group, or racial groups that one has been in contact with. In social psychology, the cross-race effect is described as the "ingroup advantage," whereas in other fields, the effect can be seen as a specific form of the "ingroup advantage" since it is only applied in interracial or inter-ethnic situations. The cross-race effect is thought to contribute to difficulties in cross-race identification, as well as implicit racial bias.
A number of theories as to why the cross-race effect exists have been conceived, including social cognition and perceptual expertise. However, no model has been able to fully account for the full body of evidence.
History
The first research study on the cross-race effect was published in 1914. It stated that humans tend to perceive people of other races than themselves to all look alike. All else being equal, individuals of a given race are distinguishable from each other in proportion to their familiarity or contact with the race as a whole. This does not hold true when people of different races familiarize themselves with races different from their own.
As research into the cross-race effect continued, multiple theories arose as to why the effect exists, including the contact hypothesis, different processing mechanisms, social cognition, feature selection, and cognitive disregard.
This brief starts where responsible research should: with the source description of “Cross-race effect” as tendency to more easily recognize faces of the race that one is most familiar with (usually one's own race). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as tendency to more easily recognize faces of the race that one is most familiar with (usually one's own race). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q820926. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1914.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
