Brown trout question

I thought that browns were supposed to be very cautious and wary.

I've wondered if their rep for being smarter isn't just due to an increasing
preference for nocturnal feeding as they get bigger. The smaller brownies
I've fished for seem no more cautious than any other trout.

I wonder if surviving populations of rainbows or brookies wouldn't become
equally cautious/night feeders if subjected to centuries of catch and kill,
like Old World browns.
