nding out what other
people think is correct

fi
ltrated cult

• Believers to be picked up by spaceship
• Preparations:
• removing metal from clothes
• rehearsing passwords:“I left my hat at home”,
“I am my own porter”
• What happens when spaceship doesn’t appear?
32.
DOOMSDAY CULT
• Rationale:Group had spread so much light that
God had saved the world from destruction
• Decision to publicize the explanation
• Before: no press, no recruiting
• After: active recruiting
• No physical proof (spacecraft/
fl
ood) for validity
of beliefs => need for social proof
Social Proof/Validation: The greater the number of people who
fi
nd
idea correct, the more an individual will perceive idea to be correct

WERTHER EFFECT

highly publicized suicide stories (car crashes increase too)
• Only in areas where suicide story was publicized
• Why?
Another Example of Social Proof (Phillips, 1979,1980)
34.
WERTHER EFFECT
• Suiciderates increases in those areas (imitation)
• 58 more people than normal commit suicide within 2 months
of highly publicized suicide
• Crash stats due to hidden instances of imitative suicide
• If young victim in story, more young people commit suicide
• If old victim, more old people
We use info about the way others behave to determine
appropriate behavior
