I doubt that was meant, either. There have been studies, most show that intelligent people are less likely to be religious. The more education, the less religion. Etc. It is, of course, a statistical thing.
(I grew up in Sweden and can tell you that to get a large fraction of (mentally healthy) people to be religious, they need to grow up in a religious environment -- without anyone really contradicting that world view. It was a bit of a shock for me the first time I went to Ireland for vacation, since I knew that a large part of the locals were really religious, but they were sane.)
An absolute value would mean rationality was totally correlated with intelligence. It isn't.
