Representative heuristic

When you see this young gentleman in a suit, what floats your mind? Doesn't he look successful or more likely attending some famous university? This is called representative heuristic because a man in suit (prototype) usually represents all of the samples of men in suit out there that are college professors, doctors, or lawyers. This isn't always true because he could just be wearing that suit for fun (Halloween) or going to the prom in it.

Representative heuristic: people assume the common characteristics/jobs of a person or object that they represent, a prototype.
