Well, this would explain a lot -
Are humans becoming less intelligent? It could very well be
Humans may be gradually losing intelligence, according to a new study.
The study, published Monday in the journal Trends in Genetics, argues that humans lost the evolutionary pressure to be smart once we started living in dense agricultural settlements several thousand years ago.
"The development of our intellectual abilities and the optimization of thousands of intelligence genes probably occurred in relatively non-verbal, dispersed groups of peoples (living) before our ancestors emerged from Africa," said study author Gerald Crabtree, a researcher at Stanford University, in a statement.
Since then it's all been downhill, Crabtree contends.

4. Sure! That's why they keep having to make IQ tests harder
(Yes, I know IQ tests aren't a terribly wonderful measure of intelligence. Neither are SATs. But both keep having to be revised upwards to keep their "average" score the same)
