First, older generation having lower IQ than newer is neither the Flynn effect nor its reversal. The Flynn effect compares historical test results to current ones; not old people vs young people but old people when they passed the test long ago with young people passing the test now. If elderly people are loosing IQ points it's most certainly because of age not because they have had a lower IQ all along.
And the reversal of the Flynn effect states that younger people are actually the one having the lower hand on this comparison.
