This explains quite a bit

I have noticed a marked decline in the number of people able to read critically and comprehend complex thinking. You can see it every day in comment sections of various blogs. There are a lot of people who appear to be unable to tell when media stories are obviously slanted by using loaded terminology or when opinion pieces are presented as news.

This study goes a long way toward explaining why this is happening.

We really need to do something about the school systems. This is unforgivable.
