The study of how humans perceive, accept, and reject truth claims—and why truth often loses to other psychological priorities. Humans don't evaluate truth objectively; we evaluate it through filters of identity (truths that support our group are more acceptable), emotion (truths that feel good are more believable), and cognitive ease (truths that fit existing beliefs require less mental work). The psychology of truth explains why misinformation spreads, why facts don't change minds, and why people can believe contradictory things. It's not that truth doesn't matter; it's that truth competes with many other psychological needs—belonging, certainty, self-esteem—and often loses.
Example: "He tried to correct his uncle's misinformation with facts, studies, evidence. The psychology of truth explained why it didn't work: the uncle's identity was invested in the false belief; correcting it felt like attacking him. The truth wasn't the issue; psychology was. He stopped arguing and started asking questions, which worked slightly better."
