If you’re smart, you trust more and are much happier

Those who are smarter than most may be better judges of character and that group may also be more trusting of other people because they are better at weighing up situations, according to research from academics at Oxford University.

The study examined data from an American social attitudes survey. 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 said.
