... if anything, I tend to think the exact opposite of this, yet oddly, today was the second time in as many weeks it's run across my mind: it's always very sad when the very pretty aren't very bright.
I am -- properly or not -- deliberately conflating bad taste and militant inexperience with "not-very-bright"-itude.
One of tonight's Jeopardy! contestants* (not the champion, obv.), Daniel, was very pretty and handled himself reasonably well. Through the wonders of Facebook**, a man might be privy to his likes and dislikes and such, and they are disappointing to say least. You really should have a decent book as a favourite before you go on Jeopardy!(.)
The other instance, which I'm not sure I ought to mention, happened when I was in Durham recently, when someone quite fetching said something more or less deeply stupid.
*Yes, another Jeopardy! contestant. Shut up.
**Oh, do the hard work yourself.
