[ExI] The downsides of high IQ

Don't bet the house on any three point difference in IQ.  It is well within
the range of error.  In fact, if retested, the percentage of people whose
scores would change by more than three points is very high.  The standard
error of measurement for the Weschler IQ test is about three.  However,
that is an average.  In fact, as the score departs more and more from 100
the error gets greater and greater.

Three IQ points is trivial and is likely not to be the cause of anything
other than test unreliability. Bill W
