During a test of cognitive dissonance, Festinger & Carlsmith had subjects participate in a boring task, then asked them to tell the next group of people coming in. The participants were then paid either $1 or $20. What were the results of the study for each of the groups (the $1 vs. 20$ groups)?
People paid $20 didn’t change any attitudes (as predicted by dissonance theory). $1 changed their attitude about the task (was less negative after than beforehand).
