Hint: when the result of scientific studies is confusing, not conclusive, it is probably better to take a step back and try to see things from a common-sense angle, because it helps deciding what would we exactly want kinds of hypotheses we want scientists to test.

So let's generate typical parenting moves that we may think could have an impact.

Positive:

• getting children hooked on reading (worked for me and I guess for 75% of LW)

• getting children hooked on sports (discipline, mature thinking, a friend's 13 year old athlete daughter is literally the most adult thinking child I ever saw)

• an athmosphere of ambition and confidence (don't think CEOs are a separate kind of people who reproduce amongst themselves, think like you can become one)

Negative:

• the usual kind of violent, abusive, drunken non-parenting, the chaotic environment of parents with problematic personality disorders

• not insisting on things like homework, not caring about grades

• anti-intellectual athmosphere at home, against studying, "why care about geography just be a miner like your dad"

• unpredictable parenting

The question is, are they testing these?
