I was recently asked to give a talk about one of the chapters, which covers an evolutionarily-informed biopsychosocial model for why certain people (and we as a species) have OCD.<\/p>\n<p>Briefly, I cover what we know about psychological (behavioral, cognitive, cognitive-behavioral), biological (genetics, neurotransmitters, and brain structure), and evolutionary causal factors for OCD. I also illustrate each one of these levels using a case study, and then tie them all together (using the same case study to illustrate a comprehensive etiological model).<\/p>\n<p>It is presented below for your viewing pleasure.<\/p>\n<p><iframe loading=\"lazy\" title=\"Caleb W.
