Scientists and other people who use mathematics every day are more likely to be atheists.
So on average one would expect atheists to struggle less with mathematics.
The answer is of course that Pascal’s Wager is old news if you have studied mathematics, not that we “struggle with mathematics” - which seems deliberately uncivil, correct me if there’s some pleasant interpretation.
The Wager offers only two alternatives, “Believe in Christ” and “Be an atheist”, which is the Fallacy of the Excluded Middle, and in this case there are a huge number of possibilities other than these two, many of which also claim to offer infinite gain.
Thus I refute it!
I would add also that a God who chooses to play deliberately deceptive logic games with His own creations seems like a cruel and capricious God indeed.
