I would argue that the movie implies that the bell curve is shifted downward so the median IQ or better yet the median of intelligence
The single most famous and well-established unexplained phenomenon in the field of IQ testing is the Flynn Effect: that the bell-curve has been shifting upward by about 3 points per decade, continuously, linearly over time, since IQ testing began, everywhere.
For the record, that amounts to a standard deviation in 50 years. The definitions of the lower edge of "gifted" and the upper edge of "mentally retarded" are 2 standard deviations.
So this entire discussion has been utterly bizarre to me. The single most famous trend in IQ is that it's going up. Why would anyone base even a bogus argument on the idea it's going down??
