Flynn's research has now provided the strongest answer. The amount by which IQ test performance has improved for whole nations exceeds the IQ difference between blacks and whites in the United States or other groups in other countries.

While Flynn's work is widely known among academic specialists, it remains largely unknown to the general public.

That is an especially painful loss, not only to our understanding of the complex IQ issue, but also to our understanding of the need to be able to discuss controversial issues rationally, instead of emotionally and violently.

Last year Jim Flynn debated Charles Murray at the American Enterprise Institute in Washington. It was a model of how two decent and honorable people should rationally confront their differences over serious issues.

In his final summation, Flynn mentioned Arthur Jensen for the first time that day, saying how shameful it was that people had lashed out at Jensen instead of dealing with his arguments -- arguments that Flynn has done more to rebut than anyone else.

Jim Flynn is scheduled to return to his native United States this month, as part of an international tour to promote his latest book, "What is Intelligence?"

He is scheduled to talk at Harvard, Berkeley, the University of Chicago and other academic institutions. But thus far there is little indication that any of this will reach the public through the mass media. That is truly a shame.

We need both his knowledge and his example.
