To me it depends on the board and the players completely. Against some players i'd go allin if they raised and others i'd muck if the board and stack sizes were right. When most people bet they're basically saying "I have the best hand". When people raise them they generally believe they have that person beat. You as the original bettor have to decide if you trust their evaluation or if they are bluffing.

Some people just don't bluff enough in a game theory sense and don't ever deserve to be paid off by you. You will crush them over the long term by never paying them off(That is if they don't adjust). Their reraising standards are so tight that even if a hand seems improbable it becomes very likely that they do indeed have what they represent. Barry Greenstein discusses this in a pot limit Stud/8 hand in Ace on the river.
