Small-Scale Question Sunday for March 29, 2026

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

The teacher assessment was a survey on their grades, so not quite subjective. Re the second study:

Yes, but they also asked the teachers to evaluate their grit and self-control, if memory serves.

Really, Roma populations should be excluded from most studies.

Interesting.

Even if these are still small impacts, they are notable considering the short duration and relatively low intensity of our intervention and that evaluations of human capital interventions often yield fade-out effects over longer time periods

Right - if these minor efforts had good effects, it seems likely that a more prolonged effort earlier in life would have stronger impact.

That kind of sucks!

Again, you aren't addressing the point that studies that screen out environmental effects will screen out the effort OP wants to do.

If you told a youth that their hardest work will only move the needle by 1.7% annual earnings, he would probably conclude in himself that it’s not worth it to be faithful to the “gospel of hard work”.

If I told a youth this he would probably laugh at me for suggesting that getting lectured in class from time to time had that much of an impact on his life choices.

And if all that this can do is bring a 70k yearly salary up to 72k, it’s just not worth it.

I would happily accept a lecture telling me to work hard in exchange for an extra $100,000 over the course of a 50 year career! I would accept a lecture from you in exchange for $2000 right now! A monthly lecture, even!

Maybe there’s another study that finds a greater effect and I haven’t seen it?

Again, unless any of these studies you've dug up are looking at home life, we can assume that school intervention studies will control for home environment which means they tell us nothing about OP's plan.
