If i'm wiser than my PC, are you going to force me to do unwise things?
Force you to? No.
Not that I've ever run into this as a major problem in practice, but I might well withhold XP from you if you played significantly against your mental stats.
This is part of the reason I strongly prefer point-build style chargen in games.
This way, if you play a character with no social interaction skills or a dullard, you, the player, chose to do so.
It isn't like the GM is standing over you with a whip, saying that you only get one shot at rolling the dice, and you're stuck playing what you get on pain of a thrashing, or something.
The player always has a choice. If you're using random creation, then the player ultimately still chooses to take the character as a whole. You don't like what you got? We'll talk about it and maybe re-roll, or adjust the stats a little.
