President Trump believes in IQ tests. He’s not wrong.

The Washington Post:

Most scientists feel a certain nervousness when the topic they research appears in the news. Overstatement is par for the course, misunderstanding a near-inevitability. But what could be more cringe-worthy than the president of the United States engaging in a macho contest with his secretary of state over the area you research? I am, of course, talking about IQ testing.

In fact, IQ tests tell us much more than that, as a mountain of evidence from the fields of psychology, sociology, neuroscience, genetics and epidemiology attests. For instance, we know that people who do better at IQ tests tend to do better at school, in work and in terms of their physical and mental health. On average, they even live longer — and this doesn’t seem purely due to education or social class. Studies continually appear in top neuroscience journals linking MRI measures (such as the overall volume of the brain) to IQ scores, and some of the first IQ-related genetic variants are now being uncovered.
