OKTrends found that those who answer ‘no’ to that quesion have slightly better than 2:1 odds of being at least moderately religious.
That doesn’t mean that those who say ‘yes’ are equally non-religious.* However, it seems safe to say that those bothered by spelling and grammar errors corrolate at least slighly with less religiosity.
But why would the non-religious sweat the little stuff more? G.K. Chesterton was reached for comment:
“If there is one thing worse than the modern weakening of major morals, it is the modern strengthening of minor morals. Thus it is considered more withering to accuse a man of bad taste than of bad ethics. Cleanliness is not next to godliness nowadays, for cleanliness is made essential and godliness is regarded as an offence.”
( *—For example, if you honestly answer ‘yes’ to the question “Are you an astronaut?” then the odds may be 6:1 that you are also male, but if you say “no” then the male-female ratio becomes about 1:1.)
