Letter IQ tests measure potential, not accomplishment

From Mr George R. G. Turnbull

Sir: Should Dr James Tooley ever have the misfortune to be under the surgeon's knife, I hope that he will be able to take comfort in the fact that the surgeon's IQ was high at the age of 10 - rather than worrying about his or her skills as a surgeon, which need not be examined under his hypothesis.

Yours faithfully,

George R. G. Turnbull
