It's not feasible to get scientific evidence for the effect of any culture on individual intelligence or laziness. This is true for all cultures including religious and ethnic. There's zero scientific evidence that any such culture is good or bad for you. You can't run a randomized controlled trial, and epidemiological techniques are unable to separate out all the confounding factors. There's also no scientific evidence that, say, Typescript is better than Javascript. Just anecdotes and opinion. Those are worthwhile, though. You have to choose somehow. So please don't reject sincere opinions for not having scientific evidence when none is available.
