Epilepsy Experiment Continuation:
80% of subjects are likely to help if they are alone, but significantly less likely to help if they
aren’t alone. This is because when alone, diffusion of responsibility is destroyed (i.e. no one
else is present to take responsibility of reacting to the emergency, other than the subject).
Test Question Examples:
1. Woman in Distress Experiment:
Why does this experiment test pluralistic ignorance and not diffusion of responsibility?
Test for high ambiguity (i.e. subjects may not know this is an emergency situation)
Check the witness makeup. (i.e. 2 or more witnesses present. Communication present, possible)
2. Epilepsy Experiment:
Why does this experiment test diffusion of responsibility?
Check for low ambiguity (i.e. subjects know this is an emergency situation/ someone has to help)
Check for lack of communication (which destroys pluralistic ignorance).
Know the difference. Similar questions will be on midterm!! 5 Step bystander intervention model:
(How to avoid participating in diffusion of responsibility/pluralistic ignorance)
Notice the event. (Paying attention and realizing something is happening will reduce ambiguity).
