Many such cases. Is there anything proving a correlation between religiosity and low intelligence?

I mean, even if god were real, all the evidence in the real world points to world religions being made up as tools for social cohesion and control. If you're smart u realize this but if you're dumb u just think that things r true because most people think they're true and it feels good to think they are true.
