Insight is not the same as scientific deduction, but even at that it may be more reliable than statistics.

Psychologists, like other scientists, pride themselves on being extremely modern, and therefore much better than any group of people that ever were before.

There are some geniuses among them, just as there are mental giants in any other field of endeavor.
