A couple of minor clarifications in my previous post.

Of course, I meant "results lagging strikingly behind intuition".
Several researchers in complexity theory have expressed the opinion to
me that their confidence in P not equal to NP is only exceeded by
their lack of any idea of how to explain it formally.

I should have said "discover what there is to them". In other words,
I'm sufficiently confident that there is something to these
intuitions; the only questions are what it is and how to explain it.
Anyone interested in better understanding these intuitions should at
least look at the two book chapters by J. L. Bell mentioned in my
previous post and can continue by looking at the references to the
writings of Lawvere and the Synthese essays of Bell mentioned therein.
