It has always been my suspicion that IQ might be up there with BMI in questionableness. I am saying this as someone who (according to their mother) got a very high IQ score (she can't remember the exact score “but it was just below genius, no it was GENIUS”) and has a low BMI (according to the BBC I have the body of a woman from the Philippines). At least if BMI doubters turn out to be wrong the question of losing or gaining weight is, though difficult, doable. IQ is another matter, which perhaps contributes to its debatable status.

The fact our collective Intelligenz-Quotient is apparently on the rise according to the Flynn Effect is argument enough against the validity of IQ standardised testing (or perhaps the questions and puzzles are piss easy now, not like in my day...). “In the last 100 years the IQ scores of both men and women have risen but women’s have risen faster” said IQ expert Professor James Flynn. “This is a consequence of modernity. The complexity of the modern world is making our brains adapt and raising our IQ.”
