The Availability Heuristic

The availability heuristic

A) is a time-consuming strategy,so it is employed by participants only when a judgment requires special care.
B) leads us to overestimate frequency if category members are particularly difficult to remember.
C) leads us to underestimate frequency because there are usually more category members beyond the ones we recall.
D) often,but not always,leads to correct estimates because availability in memory is often correlated with frequency in the world.
