Thank you, Hume's Razor I had not heard that one before.

... there’s something about becoming a Nobel Laureate that has a tendency to lead people to becoming cranks. Either that, or maybe it’s because mavericks who make Nobel-worthy discoveries have a tendency not always to recognize that not all of their ideas are as brilliant as the ones that garnered the Nobel Prize for them, although certainly another possibility is that winning the Nobel Prize tends to give some scientists an inflated sense of their own expertise in fields of science not related to the ones for which they won their Nobel Prize in the first place. Maybe it’s a bit of all of these. [Emphasis mine]

It might also be that people are less likely to tell these laureates straight out when they being idiots. We all need people around us to provide this service from time to time - I am quite certain I do.

In the unlikely event that Mr Montagnier is reading this ...

Sir, you are being a idiot.
