The shadow is an interesting concept as it is indirectly represented in many pop culture mediums, with few direct mentions. A well known example would be found in Mr. Hyde from Strange Case of Dr Jekyll and Mr Hyde. Their confrontations represent many of the ideas of the shadow.[64] The 1971 David Bowie song 'Shadow Man' invokes the concept

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] People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes.
