I don’t see where it’s debunked in that article, but I’d absolutely like to check out any other sources you have. I only found a Vox article that said he failed to disclose the first experiment and linked to that same page you did. To me, it seems more “scientifically unsound” due to ethical issues rather than “debunked”.
“I wouldn’t describe him as a charlatan … every journal article, every textbook is written to convince, persuade and to provide evidence for a point of view. So I don’t think Sherif is unusual in that way.”
Even that author thinks he’s just like every researcher. I dunno. I’m not seeing the debunked angle. Ethical issues, sure.
Regardless, I still think it’s quite relevant even if they were manipulating the boys somehow; do you not feel we’re potentially being manipulated by other parties to feud with one another?
