Replication

A psychologist replicated what are perhaps the most infamous experiment, showing that people really will torture others if told to do so. This is the one about shocking people and how likely subjects are to turn on the heat on other subjects. Story here. A graph explains:

More than two-thirds of volunteers in the research study had to be stopped from administering 150 volt shocks of electricity, despite hearing a person's cries of pain, professor Jerry M. Burger concluded in a study published in the January issue of the journal American
Psychologist.

And so it goes.
