This discussion can/could go many ways.
Some factors involved to get peeps thinking: (No paticular order)
Are you PFR'ing for value or a steal, or to iso a fish?
Are you Ip or OOp?
Are you against a reg or a bad player (or bad reg)?
What's your image? And Table dynamics.
Hand strength (obv)
Anyone on tilt?
YOUR 3 betting patterns. (do you 3 bet strictly for value or have a polarized 3 betting range?)
Opponents range/tendendcies for 3 betting (see above)
(each factor can be a huge post in itself, so this lil one part may even jump around.
I'll start w/bad passive players. They are typically not 3 betting lite. The fish will call all the way w/total cheese. But they usally have something when they're showing agression. This doesn't mean they're not 3 betting TT or JJ, but you'll have to rely on their history to determine that. Not to mention they will often just call w/AK, AQ types. So it's usally a value range for them.
Against a reg, especially w/some history, your options increase. Their range is so much wider (typically) that your value range increases. This allows you to 4 bet hands that are an snap fold against a fish and allows you to polarize your 4 betting range.. Tendencies, range, position and history are much bigger factors. OOP (and IP) against a decent reg after you call a 3 bet is just burning money, if you do it regularly I.e. you open 99 and he 3 bets you from the btn, you just call. Flop is AQ2, your hard pressed to continue when he fires, especially a 2nd barrel on a blank turn.
So OOp against a decent reg, it's 4 bet or fold imo. I think so many would benefit from thinking about this. Yes you will get floated and have to give up in some pots, but this will allow you to increase your value range next time. Which is information gained, so you benefit.
I ramble a lil .
But here's a nugget I found a few years ago from a high stakes player that I've found in valueable many times.
"if his range is wide enough to call, its wide enough to 4-bet. if his range is tight enough to not 4-bet, its tight enough to fold. in general."
