Nobel Prize winners won the prize because they had unorthodox ways of thinking that led them to an actual discovery. I'd think that it's quite normal that 1 out of 10000 unorthodox beliefs ends up being a scientific reality of high impact.
i.e. ~1 out of 10000 unorthodox thinkers will win the Nobel Prize, 9999/10000 of those thinkers you will never hear about. For the one who won, it's likely they will have continued unorthodox ideas, 9999/10000 of which will not lead to a second Nobel Prize.
I agree that the share of unorthodox thinkers should all in all be higher among those winners. This is indeed what made them advanced in their field. But the main bias remains: looking at those whose voice reaches even when they venture out of their field rather than the full pull of (good) scientists.
A lot of discoveries are made by someone who "imported" insights from one field to another.
This is precisely what I meant to say (and seemingly failed) and why I upvote you!
