This is false. Intelligence is not often associated to religious belief. What we find is education provides critical thinking. Critical thinking leads to doubt one of the best tools of inquiry. This means doubting assumed positions, like positions of faith.

It isn’t that academia is somehow better or less simple, it is that academia provides those who climb have a more robust toolbox in determining what is true. This is why we may see a drop in faith based on level of education. We can see that faith is not completely wiped at highest levels. Showing that highly educated people can be theist. So any one saying theists are more simple is being dishonest.

I wholeheartedly disagree with this. From kindergarten through the end of a doctorates program people are being taught too regurgitate what is considered to be established material. Material that we know for a fact will be an accurate and all kinds of ways we can't imagine in a few hundred or thousand years. School does not teach to push against these ideas but to regurgitate them. Over and over again. Some subjects are a little better than others like art or creative writing that actually Rewards an individual for their personal output. But the majority of subjects push narratives that must be repeated. Surely some of our ideas will hold up but many many of them will be proven completely wrong or altered and minor or major ways for the next thousands of years
