Vernon is the former editor-in-chief of the scientific journal Personality and Individual Differences and formerly sat on the editorial board of Intelligence[1][2] and the board of directors of the International Society for the Study of Individual Differences (ISSID).

According to their website, "he and his collaborators at the University of Western Ontario used state-of-the-art Magnetic Resonance Imaging (MRI) techniques and found that IQ scores are related to brain size.

In one study, they reported the results for 40 adult females for whom the correlation between brain size and IQ was 0.40.

In a subsequent study, this time of 68 adult males, they again found a 0.40 correlation between brain volume and IQ.
