Thanks for the link. I added these to the list! Now over 250 questions!

I wonder what spelling and grammar mistakes have to do with religiosity!

Apparently nothing, but there is a correlation.

Here is what the article has to say about it.

If your date answers 'no'—i.e. is okay with bad grammar and spelling—the odds of him or her being at least moderately religious is slightly better than 2:1.

As someone who is not himself a believer, I found it rather heartening that tolerance, even on something trivial like this, correlated with belief in God, although I should've figured out that religious people are okay with small mistakes. Next to intelligent design, what's a couple typos?

It's also nice when two completely independent datasets corroborate each other. Last summer, we analyzed the profile text of half a million user profiles, comparing religion and writing-level. For every one of the faith-based belief systems listed, the people who were the least serious wrote at the highest level.

More likely, it's that there's a correlation between low intelligence and religiosity (https://en.wikipedia.org/wiki/Religiosity_and_intelligence). And, of course ,there's a correlation with bad spelling and low intelligence.

So a religious person is more likely to be okay with spelling mistakes because they themselves are likely to not be good spellers, because they are likely to be less intelligent. It has nothing to do with religious people being okay with small mistakes.
