Many thanks to Jim for pointing out the supplement which makes a number of points in the article clearer.. [snip] >On the study itself, I would wonder about the mechanism.

An alternative view is to ask why do homicides occurs in a comunity? There presumably are a number of variables that increase the probability of the occurance of a homicide (I believe that outdoor temperature is a predictor, that is, homicides are more likely to occur in hot weather than in cold but mere temperature cannot be the inducement to homicide, rather people may be more active outside more during hot weather, more irritable and so on -- all of these factors would also presumably be correlated to IQ and homicides may act as a moderator, mediator, or merely correlated with IQ). One needs to consider why homicide occurs in order to understand whether there is a real relationship between homicide and IQ or a spurious one. -Mike Palij New York University [email protected] --- You are currently subscribed to tips as: [email protected].
