“Godwin’s law” refers to an internet phenomenon whereby, in any ongoing discussion, on any topic, it is only a matter of time before one of the comments will make a reference to Hitler or fascism.
My most popular post by far has been the one on the “nutrascience scam” which has now had almost 20,000 visits. Also it has attracted 233 comments, and so far Godwin’s law has not applied. Scientifically speaking I think that that may constitute enough evidence to support the view that the probability of Godwin’s law applying is not 1, but <1.
Having said that I fully expect now that someone will go and put a mention of Hitler on the thread just for the hell of it.
