Lowering of some aspects of intelligence across history (the revese Flynn effect) is observed in areas where schools have likely little to no effect. For example there is a Piagetian test of intelligence involving water displacement or whatever, the child is required to understand that it's volume and not weight that displaces water. and in the 1900s about 35% of kids were able to pass it. Today the pass rate is 17%. And it's not like we removed some water experiments from kindergarten or elementary school... children just don't process real-life problems all that well anymore.
