Dr. Anna Machin is a British evolutionary anthropologist at the University of Oxford who studies the neuroscience and psychology of love. Anna and I talk through what science actually says about attraction, attachment, and long-term relationships, and why so much modern dating advice gets human nature wrong. We get into dating apps and how they shape behavior, whether love at first sight is real, what attachment styles do and don’t explain, and what science says about polyamory. We also discuss common myths about pheromones, love languages, and whether having kids really makes people happier.
