Study: Clever people are more trustworthy!

Bright individuals may also be more trusting because they are better at weighing up situations, according to researchers from Oxford University. The study, published in the journal PLOS ONE, examined data from an American social attitudes survey, which evaluates people's social status, their behaviour and social attitudes, and their intelligence.

It also found that people who are more trusting are more likely to have better health and greater happiness. But the links between trust and health, and between trust and happiness, are not explained by intelligence, they added.
