The reverse Flynn effect should be by far the most concerning thing on this page. As others have pointed out, some of these trends are specious, but the Flynn effect has held up for a while, and is highly replicated. Even just the disappearance of the Flynn effect would be significant.
An adjacent phenomenon that needs investigation is "Adult ADD". Extending the theory of adolescent ADD to adults doesn't add up. It's surprising that these are considered by default to be the same condition, especially in people who didn't have issues during adolescence. The increase in prevalence demands a non-genetic explanation. Better explanatory theories are:
1. We've collectively decided that this is how we dispense amphetamines to consenting adults.
2. It's a fad (when will prevalence decrease?), and
3. It's the smartphones/apps.
Personally, I think it's mostly 3, with the infinite scrolling apps having a huge effect on attention and executive function, but also some of 1 given the information economy.
This should go without saying: if an intervention is working for you, or a disease theory has given you explanatory power, you should stick with both.
