(146,218 posts)But I am not convinced that it really addresses your questions about religion. While there appears to be some correlation between "tightness", which could also be stated as low tolerance, with religion, it is not clear which may be lead to the other.
As noted elsewhere, the map also reflects a correlation with lower socioeconomic levels and all that encompasses, which has also been correlated with religiosity.
In terms of your question, of course it is lazy and faulty to say anything is just because of religion. As you point out, the category is too board and it's members too diverse. In addition, there are way too many other variables. Having a religious affiliation or no affiliation can be correlated with just about nothing when it comes down to it.
