Why do some young men turn to crime, while others don-t? An international study shows that preferences such as risk tolerance, impatience and altruism as well as self-control can predict who will commit crime. Risk-tolerant, impatient young men are more likely to commit property crime, while people with low self-control tend to commit violent, drug and sexual offenses.

Chimpanzees don-t automatically know what to do when they come across nuts and stones.

Their culture is therefore more similar to human culture than often assumed.
