Myside bias

Biological Parallel

Immune systems exhibit a form of 'myside bias' through self-nonself discrimination—T cells are trained to ignore the body's own antigens while attacking foreign ones. This recognition pattern, established during thymic selection, becomes so entrenched that immune cells will mount autoimmune responses rather than reassess their targeting criteria. The parallel is striking: once the immune system commits to a classification schema, contradictory evidence (self-antigens presented in new contexts) triggers attack responses instead of belief revision.
