- Imagine that the penalty for taking drugs just one time was life in prison
- What would your attitude towards drugs be?
- If they were very mild – 10 dollar fine?
- The $10 fine would be more likely to affect how you feel about drugs because
you internally have to come up with reasons as to why you don’t use drugs.
- The Forbidden Toy (Aronson and Carlsmith)
- Punishment, Dissonance, and Self-Persuasion
- 2 groups of kids – 1 forbidden toy
- ½ given severe threat and other half given midl threat
- Experimenter leaves the room and returns
- Children asked to rate how desirable they found the toy.
- It turns out that the children given the severe threat found more desire in the toy
than those in the mild threat.
- Would it have an effects on behavior –
- Could play with toy, one toy was really amazing.
- Severe or mild threat
- See if the child would play with toy under each circumstance, and if it would have
a lasting effect.
- Kids in severe still wanted to play with toy and mild didn’t
- WEEKS later they could play with whatever toy they wanted, the amazing robot
toy was still part of the group of toys
- It turns out that even several weeks later, the mild threat children from the first
study were much less likely to play with the toy in this follow up compared to
those in the severe threat.
- The mild children internalized the reasoning as to why they didn’t play with it
while the severe externalized it, so the mild children kind of convinced
themselves they didn’t really like or want to play with the toy.
- Power of Insufficient Justification
- Large rewards and punishments have different consequences for behavior
compared to small ones
- Large reward/punishment = external justify = temporary change
- Small reward/punishment = internal justify = lasting change
- Justification of Cruelty; Blaming the Victim
- Sometimes dissonance has more serious consequences
- Cognitive dissonance and motivated reasoning
- The “Just World” hypothesis
- In War – dehumanization of the “enemy” helps reduce dissonance
