Local 6, an Orlando news station, recently conducted a "missing child experiment." They plastered posters all over a mall claiming that 8-year-old Britney Begonia was missing. Then they had Britney herself sit down alone a few feet from some of the signs. The question was: would anyone notice the poster and offer to help Britney?

The predictable result: Of the hundreds of people who walked past and saw the posters, only two stopped to ask Britney if she was OK. Many people, questioned later, said they noticed Britney's resemblance to the girl in the poster, but were "fearful of getting involved."

It's the unresponsive bystander effect, well known to social psychologists. People don't like sticking their neck out to get involved in a potentially uncomfortable situation, especially if no one else seems to be doing so.

I just realized that Local 6 is the same station that ran a similar experiment back in February that I posted about, in which they had an actor pretend to be a criminal breaking into a car, and filmed the non-response of bystanders on the streets. They evidently think unresponsive bystanders make for compelling news. And luckily for them, social psychologists have devised all kinds of situations in which to test the phenomenon, including the bystander response to arterial bleeding. So Local 6 shouldn't run out of material anytime soon.
