Confirmation Bias and Its Effects on Belief Perseverance

Quick fact

In one classic study, participants who were given evidence that a suicide note was fake continued to believe the deceased person (whom they had earlier judged as suicidal) was at risk of suicide, even after the evidence was retracted. Their initial belief persevered.
