Yes. The Flynn effect averaged out over the whole spectrum appears to be about 3 points per 10 years, and this seems to hold pretty well for the middle of the curve, but it appears to be greater at the top end of the curve (and some evidence suggests that it may be less at the bottom end of the curve). Since we don't really know why it occurs, or what the shift in standard scores represents at a functional level, it's still a bit difficult to explain or predict the changes. (I think I have speculated elsewhere on the forum some of the possible explanations, but we still don't REALLY know.)
