The Representativeness Heuristic
Captions available
The idea
The representativeness heuristic judges the likelihood that something belongs to a category by how much it resembles the category's prototype.
In practice
A quiet, orderly person is judged more likely to be a librarian than a salesperson, despite far more salespeople.
Where people slip
Resemblance ignores base rates. The size of the categories is the information being discarded.
