The current study explores the impact of dissonant origin information (information about character origin that counters audiences’ prior knowledge) on dispositional shift (movement from more to less extreme judgments). In a 2 (action: pro- or anti-social) x 2 (outcome: rewarded or punished) x 2 (canonical/control or dissonant origin) between-subjects experimental design, participants receiving dissonant origin experienced greater dispositional polarization (that is, dramatic shift) – from extreme positive to extreme negative judgments; these effects intensified when the character’s actions were anti-social.
