Generally the requirements to become a cardinal filter out those with a truly low IQ, even to become a priest requires years of study. I have no doubt the modernists relaxed the standards, but its a near certainty that black priest is at least 80IQ (compared to the sub-saharan average around 60) while a black Bishop would probably be in the white IQ range.
