Bad Apples or Bad Barrels? The Short and Long Versions of Zimbardo on the Lucifer Effect

I am very happy to discover two different versions of Dr. Philip Zimbardo's lectures about the content of his book, The Lucifer Effect: Understanding How Good People Become Evil.

In the longer version of the talk that was presented at MIT, he gives a more detailed description of how he looks as systems and how systems and environments promote bad behavior. It is, of course, a much longer video, nearly 2 hours long. There is also a shorter version, circa 24 minutes long, but it does not include as detailed of a description of the "bad barrel" promoting "bad apples."



LONG VERSION
(MIT Lecture - 1 hour 58 minutes)

SHORT VERSION 
(TED Lecture - 23 Minutes)
