From the examples given in this article it is absolutely impossible to tell whether the "incorrect beliefs" (be it racism, mushroom aliens, vitamins curing cancer, whatever) are in any way connected to the Nobel prize.

For all I know, they all could have been racists, psylocibe users, etc. long before they received any prizes and the associated attention.

In fact, it could even be possible that they had much worse and radical beliefs earlier in life which were tempered by the burden of being a thought leader.

I'd go as far as to say that this is a good example of an article that should be removed from Wikipedia.
