The men and women who performed best in the Army’s I.E.D. detection study had the sort of knowledge gained through experience, according to a preliminary analysis of the results; but many also had superb depth perception and a keen ability to sustain intense focus for long periods. The ability to pick odd shapes masked in complex backgrounds — a “Where’s Waldo” type of skill that some call anomaly detection — also predicted performance on some of the roadside bomb simulations.
It reminds me of Malcolm Gladwell's Blink. I did find it a bit frustrating because it essentially argued that we have instincts that are often quite sharp and accurate, except when they are not. It was a fascinating book with lots of good pop social science, but not quite as strong as his first book, Tipping Point, or his more recent one, Outliers.
