So you think ACEs aren't heritable? Wanna bet? Actually, I was curious about this and found https://www.nature.com/articles/s41398-021-01538-w https://www.nature.com/articles/s41398-021-01538-w - which indeed has Plomin as a coauthor. It's a twin study, and it does argue that ACE has an independent effect from genetics. In fairness to Plomin, I don't think his argument was ever that you couldn't screw up your children if enough bad things happened to them.

  I think it goes without saying that an experience cannot be inherited, a term which exclusively applies to genes. If we want to rhetorically expand the term "inherited" to mean "a parent may visit upon their children something visited upon themselves", then that weakens the initial premise of genetics mattering and environment (which includes the one the parents present, consciously or unconsciously) does not.

    there was a study that traced obesity in a certain group of people in sweden to a famine in a town where the ancestors of these people lived several generations earlier. if that study is accurate then some experiences can translate into genetic effects.

    No, what I mean is that identical twins will be more similar on measures of ACEs than non-identical twins. Of course events aren't in the genes, but the propensity to have events happen to you can very easily be in the genes. This might be surprising, but the history of behaviour genetics is basically "everything being surprisingly more heritable than people thought". Indeed, from the article I cited: "HPA-axis function and depression are both influenced by genetic factors, which could increase the individual’s vulnerability to ACEs"; and here's an article that shows that being a victim of violent crime has heritability of around 20%: https://ajp.psychiatryonline.org/doi/full/10.1176/appi.ajp.159.10.1675 https://ajp.psychiatryonline.org/doi/full/10.1176/appi.ajp.1....
