COGNITIVE DISSONANCE is a psychological state, observed when a brain holds onto a belief (about reality) in the face of persistent contradictory evidence; by somehow ignoring it. COGNITIVE DISSONANCE is stressful but not as disturbing as having to explode a belief. The brain’s natural non-stress state, however, is COGNITIVE CONSONANCE, where belief is evidentially and consistently in alignment with reality.
The less easily observed but nonetheless essential enabler of COGNITIVE DISSONANCE is known as COGNITIVE ASSONANCE. ASSONANCE recasts DISSONANCE with most of its stress removed so it feels almost as natural as CONSONANCE.
