Had a look at the article and the claim “a news study shows”. That’s notice, but inconclusive.
To even begin to take such a claim seriously I’d need to see several peer reviews papers which had used used very large populations in their surveys.
In the meantime my basic position remains unchanged: An atheist is a person who does not believe in gods. Nothing else is implied or my be inferred. It is most certainly not a moral, philosophical or ideological position.
My moral code is based on ethical egoism. I’m also rather fond of stoicism and even find hedonism interesting.
