The Difference (8.00 C4). Final (and perhaps the least satisfactory) of this population-genetics series which spends unnecessary time on the ideas of Charles (The Bell Curve) Murray. (If, as programme one argued, most "white" North Americans have some "African" genes, why bother with work that puts people into crudely determined racial groups?) There are also some more interesting contributions, for instance from UCL’s Robert Turner on functional brain imaging and Yale psychologist Robert Sternberg on different types of intelligence. Perhaps the following day’s The Difference Debate (Monday 11.55 C4) will question some of the series’ bald assertions.
