Does a higher IQ lead to a questioning of there being a god?

I would think if God existed that the more intelligent one is the more likely they would be to understand and believe in God.

IQ numbers prove little about ones actual intelligence.
IQ tests have been proved to be racially and economically skewed.
Faith is not impacted by intelligence or lack of intelligence, and for the vast majority is not blindly adopted (those are generally the ones that fall away) or void of study and questioning, despite what many of lower intelligence claim.
