According to Lab Notes, new research is suggesting that a higher IQ is an indication that you may live a longer life.
A number of recent studies have been finding that people who score lower on intelligence tests (notice how careful I am not to say “smarter people”) tend to die earlier than those who score higher. The effect doesn’t seem to arise from socioeconomic factors (well-off people score higher on IQ tests and also tend to be healthier), leaving scientists to reach for hypotheses. Maybe high-IQ people smoke less? eat healthier? follow doctors’ advice more?
Now a new study, reported in the September issue of the journal Psychological Science, finds an even more intriguing connection.
