Also known as "Godwin's Rule of Nazi Analogies". Originated by Richard Sexton, and popularized by Mike Godwin of the Electronic Frontier Foundation (and of the Wikimedia Foundation until 2010) in 1990 in the form: As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches one. Reformulated in the Net.Legends FAQs "Usenet Rule #4": "Any off-topic mention of Hitler or Nazis will cause the thread it is mentioned in to come to an irrelevant and off-topic end very soon; every thread on Usenet has a constantly-increasing probability to contain such a mention."
That is very interesting, Geoff. Interestingly, I had always thought psychopaths were 100% negative, but apparently they have some positive characteristics, too.
I do think it hard to psychologically analyze from afar, and not that scholarly. However, it's in Scientific American, so it was all peer reviewed. I certainly can see a lot of those characteristics in Trump.
