Well those are just stupid religious ppl. There are stupid irreligious ppl as well who will say the earth is flat bc that’s what they visually observe. I’d say both intelligent and stupid people come in all creeds or lack thereof, but that most intelligent people historically have been religious of some kind (bc most people historically and even now in fact are religious). The Muslim guy who invented algebra legit started his treatise out by thanking and praising God on and on
I think they mean in modern times when it’s not the end of the world if you aren’t religious. Also #5 most people in history were religious to some extent (wasn’t much of a choice and they were pretty much brainwashed since birth) so that likely skews data. I’d say the average modern atheist is smarter than the adv modern theist.
Well the people who figured out the world was round in the first place were religious. The vast majority of people in the world are and have been religious, that allows for more dynamism among populations with a higher likelihood of believing any number of things. What drives flat earthers is stupidity laced conspiracy culture and distrust of authority with confirmation bias, which irreligious people are just as prone to
I suppose the reasoning varies from person to person though. Some are unwilling to think about it, others are too scared to, and some are incapable of it. I will note that it’s a common sign of stupidity for someone to call anything they can’t understand or they disagree with stupid though, so perhaps there’s come correlation with that observation and OP’s phrasing 😉
