"strong" is relative to what you need the prediction for if we were trying to pick baby einsteins at birth, no it's not strong if we're trying to predict whether parental success / child success correlation is environmental or genetic, then we've explained everything right here
An r^2 of 0.05 is not “everything”, it’s literally almost nothing.
It literally says that it "...accounts for 9% of the variance in the target trait". That is an R^2 of 0.09. It's garbage.
Everything in genetics is small effect sizes. That's just how genes seem to work.
If the effect sizes are small, perhaps............... we shouldn't use it to craft public policy or predict individual variations???????
perhaps not all all population studies aim to predict individual variation, hmmm
