lead exposure makes people dumb af and mentally ill
- toomuchtodo 5y agoCrude, poor delivery but you may be on to something. I am curious if this is why you see generational differences in mental models and belief systems (there is data showing an inverse relationship between religiosity and intelligence [1] [2]), and why younger, healthier cohorts operate with different mental models. Riffing, if younger cohorts are healthier, you’d expect their average/aggregate cognitive ability to be higher, leading to social stratification.

- erikpukinskis 5y agoI’m sure lead levels have some effect, but how do you control for “they grew up in a completely different world”? I’d assume the latter is the primary cause of any major behavior differences, absent some pretty breathtaking science showing otherwise. “Intelligence” is also a pretty goofy measure. If we’re talking about IQ, it’s basically “what quiz questions predict success measures, as defined by the social norms of whoever made the test”. IMO that’s a pretty sketchy way to define intelligence. Certainly not the way I think about it colloquially. To me, success and intelligence are loosely correlated but very different traits.
