The causality fits very well into our world view. It also gives a very "simple fix". Limit video games, limit screen time, limit X.
When the real problem is significantly harder. Social, governmental, institutional and systemic racism.
If there's a real, reproducible, verifiable link, I'm all game for it, but when the problem is so wide spread and the answer is so simple, it really needs to be reproduced across multiple studies.
Because rarely is the problem + solution truly that simple.
