The field of intelligence has had its Jekyll and Hyde sides for me personally, which is why I entered the field in the first place. I became interested in intelligence when, as an elementary-school student, I did poorly on IQ tests.

In a sense, my professional career has been an attempt to understand and come to terms with my own early failures on these tests!
