Hang on... So in the second part of the study, these guys are trying to determine if the heat effects are cumulative, and find that they are not (obviously, since susceptibility to permanent damage due to > 70 degree weather would have crippled our species intellectually from the get go). They then go on to explain that parents are somehow "adapting" to this by, for example, sending kids to math camp, thus negating the cumulative effect. Huh?
