It’s not a crazier idea than most of Kennedy’s. Someone should do a study. Or make one up, nobody checks anymore.
The impact of micro plastics cannot be studied because there is no control group. Hard to say what microplastics do to the human brain when the researchers might find it hard to form a group without brain plastic
Couldn’t you still study populations with more or less plastic, even if “zero plastic” cant be found? Or is the amount of it more or less even across groups?
Throwing in my $0.02, a correlation study is technically an option, where you look at differences as microplastics increase in concentration. But. my instinct is you would see some really unfortunate covariance - that is, another variable that increases (or decreases) at the same time as microplastics and is known to impact your variable of interest, e.g. socioeconomic status.
I don’t think microplastics are having that effect.
It could just as likely be the decrease in airborne Lead following the removal of Lead Paint and TetraEthyl Lead in Petrol has caused people to be much more aggressive.
They still have the brain damage from growing up breathing in heavy metals, but no longer have the soporific effect of heavy metals.
