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.

Very interesting, thanks.
