Funny thing is, that goes for the social sciences too, IMO.

All a matter of having an open and curious mind, I suppose.

The PhD Movie introed with Richard Feinman's statement "I don't know anything, but I do know everything is interesting, if you go into it deeply enough."

Feinman was a curious character.

I suspect that with even a modest breadth of knowlegde a deep investigation of anything brings associations with existing knowledge (interest), unexpected connections and exceptions.
