Abstract: 

We propose that when faced with the difficult task of judging probability or frequency, people employ a limited number of heuristics which reduce these judgments to simpler ones. Elsewhere we have analyzed in detail one such heuristic - representativeness. By this heuristic, an event is judged probable to the extent that it represents the essential features of its parent population or generating process...
