Obviously you know why this is, but to elucidate for others, IQ score measures your relationship to the scores of the others in your age group. So the trend that you saw was not you getting dumber over time; it was simply a slowing of the rate at which you were getting smarter, like a marathon runner ahead of the pack who begins to slow towards the finish line. The people behind him begin to catch up, but he;s still well out in front.
Any other possibilities or factors? I am curious if the way we think changes over the years, and if education could actually be a stumbling block to basic abilities.
I don't know how to express it scientifically, but I know that sometimes instead of thinking critically, we can start to apply some of the learned 'fundamentals' to a problem, and thus limit the possibility we have of actually reaching an answer that is outside of what we have learned as a formula.
I also think that schraf's stats are lacking; she does not know or say how well the other children in her age-group were doing. It is quite possible that
everyone reaches this stage of leveling off. Maybe that was what your post was about?
