PSYC 215 – Lecture #12: Attitude Change Following Behavior
· Attitude usually changes only when the person judges there is insufficient justification for their
· Become more positive about their task if there is insufficient justification for it
o Ex. Being paid a large sum of money for the task vs. being paid very little
· What is your attitude toward raising tuition fees at McGill?
· [Strongly opposed] 1 2 3 4 5 6 7 8 9 [strongly in favor]

o Ex. “I smoke” vs. “smoking causes cancer”
o Smokers find a way to find beliefs to resolve the inconsistency
o 40% of smokers doubted the first reports of cancer causing agents in cigarettes

o Ex. “I chose to write in favor of raising tuition” vs. “I do not believe in raising tuition”
2) Self-Justification
· (Aronson): people have a drive to maintain, protect, and enhance self-esteem
· Inconsistent cognitions only provoke strong emotions if they are important
· Behaving inconsistent with one’s attitude threatens positive image of self
o Ex. I”I believe one thing but acted very differently, therefore I am a hypocrite!”
· “Self-Justification: model of dissonance:
