The four laws of behavior genetics (each supported by hundreds or thousands of studies) HT @SteveStuWillpic.twitter.com/hU2l9zOhrp

I don’t understand the third law. If it isn’t the environment or genetics that explain the variance in behavioural traits, what else explains it? What do behavior geneticists hypothesize it might be?
Random neurodevelopmental noise. The stuff that makes identical twin animals different from each other even if raised in the same habitat by the same parents.

But isn’t random neurodevelopmental noise in part a product of gene-environment interactions?

No, it's something different, and it's not predictable by GxE interactions.
