He found the student in question because she made a Facebook group. If I can search Facebook, Lewin can search Facebook too.
I can understand both sides of this position. I found out about the Lewin controversy a few weeks ago; I was at loose ends, and decided to go back and work through the Lewin lectures, which I had started and abandoned awhile ago. The lectures really are exceptional. There is no doubt about it. But when I went to the MIT site, discovered they weren’t there (they are no longer in OpenCourseWare, harvestmoon, that’s where I looked) and started Googling, I soon realized that MIT simply should not let itself be a vehicle for distinguished professors to harass women students. The lectures are exceptional, but Lewin’s conduct was egregious.
There is no doubt that Lewin did what he was accused of. He doesn’t deny that he did it, but he still maintains he did nothing wrong. Ugh.
