His TED talk on the psychology of evil Which I would bet you $1000 the people behind the right wing push know very well

The nature of evil and the making of heroes.

but he won't be remembered for it, at least not by the public. It is sad to see him pass but he seemed to live a long full life.

If you feel like sharing. Mahalo (thank you)

This doesn't negate the other good work he did in social psychology.

the foundation of his career reputation is built upon the stanford study.

if he falsified that, what else has he done?

the power of the situational factors relative to the individual difference factors (e.g., personality) were over-stated. Furthermore, it appears Zimbardo provided some coaching to the "prison guards" on how they were to behave, which certainly was a manipulation and one that would likely influence the guards' behavior toward the inmates. There are numerous ethical considerations too in how the study was conducted. I don't know that you could go as far as to say the study was "falsified." The main problem, from a research perspective, is that it would be hard to make strong inferences about human behavior because of the weaknesses of the study.

I don't think his poor work on this study should lead us to question the legitimacy of all his subsequent work. By his own admission, this was a poorly designed "experiment" that got out of control, and he acknowledged his own role in this. His own peers and journal editors and the journal peer-review processes would possibly have detected gross scholarly misconduct if it were a pattern in his subsequent work.

Snip

A new exposé published by Medium based on previously unpublished recordings of Philip Zimbardo, the Stanford psychologist who ran the study, and interviews with his participants, offers convincing evidence that the guards in the experiment were coached to be cruel. It also shows that the experiment’s most memorable moment — of a prisoner descending into a screaming fit, proclaiming, “I’m burning up inside!” — was the result of the prisoner acting. “I took it as a kind of an improv exercise,” one of the guards told reporter Ben Blum. “I believed that I was doing what the researchers wanted me to do.”

Willingly gullible Americans. Always a money grab somewhere.

Do you think it is true that average people can easily be persuaded to be cruel by appealing to authoritarian ideas?

He's a giant in Social Psychology.

you can do plenty of great things, but if you make one massive scam mistake such as he did, that sullies a career.

everything else now is called into question.

It would be a shame to remember him only for the Stanford study (I hesitate to call it an experiment).
