Are Americans getting smarter....?

So says the New Yorker:

Twenty years ago, a political philosopher named James Flynn uncovered a curious fact. Americans—at least, as measured by I.Q. tests—were getting smarter. This fact had been obscured for years, because the people who give I.Q. tests continually recalibrate the scoring system to keep the average at 100. But if you took out the recalibration, Flynn found, I.Q. scores showed a steady upward trajectory, rising by about three points per decade, which means that a person whose I.Q. placed him in the top ten per cent of the American population in 1920 would today fall in the bottom third.

But, this isn't correct. Intelligence scores are lower than the 1980's average. How do you explain that. The increased scores from 1900 to 1980 is because of increased percentage of people with primary and secondary education.
