>this is a very pre-replication crisis book. I don’t hold this against the author, I don’t think anyone’s really proud of what they believed pre-replication crisis, but it’s undoubtedly a product of its time. Mirror neurons, candidate genes, left- vs right-brained people, etc all make dramatic appearances. Nothing (except the genetics parts) are inexcusable or even certainly wrong, but all of them together concern me. And several of the book’s key studies are contradicted by later, larger studies. Van der Kolk talks about how childhood trauma decreases IQ, but some pretty good studies say it doesn’t. Even the studies that have passed the test of time look a little weird. The Adverse Childhood Experiences study found that obesity and other seemingly nonpsychiatric diseases were linked to child abuse, and recent studies confirm this – but the controls for socioeconomic status are always insufficient, and there’s surprisingly little shared environmental component. I’m biased about this, everyone’s biased, but part of the book was meant to prove that child abuse mattered shockingly more than you thought it possibly could, and that part was wasted on me.
