I wonder if there’s some sort of correlation between the literally 2x numbers for both the 18-24 group and the 2 or more races group. Is it because interracial marriage has become much more common lately so multiracial people skew young or is it due to other factors.
My guess is that pollution is the root cause.
Particulate matter
Pfa pfs
Bpa
Microplastics
Nitrous oxide (car engines)
And other things that can pass the brain blood barrier
Society banned lead, asbestos already, but there are so many more.
Or: 77% of U.S. adults have never been seen by a psychologist (2022)
