The thing the available evidence can show us is that variations in parenting choices don’t explain much variation in outcomes, among the populations studied, which tend to be WEIRD and in the case of adoption studies have passed an explicit bar for estimated parenting quality. This is not the same as “parents don’t have much of an influence on the development of their own children”, which is easily disproven by looking at the 5th percentile parents.
Not quite. The point is that the studies are mostly done on parents with pretty similar styles, so there isn’t enough variation in parenting style to lead to detectable variation in outcomes. It’s the equivalent of studying how water affects plant growth, but giving every plant in the range of 5% of what you think their ideal is, while varying other factors (light, nutrients, plant genetics) tremendously. Your results don’t show that water doesn’t matter for plants, they show that the impact of that small variation in water is lost amongst the noise.

I am not sure I exactly understand whst that says. Something like “parenting choices are only important if they are really bad”?

Very interesting, thanks.
