Zimbardo, who by an almost unimaginable coincidence went to high school with Stanley Milgram

Wow. Like Neil Diamond and Barbara Streisand.

Not totally on topic, but how is that an "almost unimaginable coincidence"? Given the number of people who are involved in similar things, and the number of people at your average high school, it pretty much goes without saying that some people who go to high school together will later do similar things.

Journalists have weird ideas about probability.
