Hmm. It might be possible to indirectly get some information about them by comparing the kinds of people that get caught for premeditated crime with the kinds of people that get caught for crimes of impulse, and then adjusting for any correlation of intelligence with self-control. The latter ought to be harder to cover up.
I’d guess people who commit crimes but don’t get caught are very, very hard to get statistics about.
