Hey, mom. Post-partum depression got you down? Thinking of leaving your husband? Don’t fight it; just let him go. After all, it’s not your fault.
It’s your hormones. That’s the latest from the world of science. According to psychologist Jennifer Bartz of McGill University, researchers have identified a link between new parents divorcing and low levels of oxytocin.
Whatever the explanation, there seems to be a familiar eagerness by researchers to impose a chemical, as opposed to a psychological, explanation upon human behavior. Scientists often appear to prefer a model that links our choices to biological and evolutionary causes, further disassociating human decision-making from that most obvious explanation — free will.
