The year is 2050, and I have been making this podcast for 30 years. In this episode, I continue with the themes first developed in the Biology of the Right-Left Divide, using the revolutions of the mid-2030s to illustrate how social conditions amplify innate differences. We focus on two ways the social-technological trajectory is changing us: specialization (i.e. the development of hyper-competence in some domains at the expense of any competence in others) and behavioral changes resulting from alterations to the brain's reward circuitry, a consequence of living among so many easy, compulsive pleasures. We build a foundation for examining how these two types of change interact with the biology of aggression, and thus determine the nature of human dominance hierarchies.
