In this episode, I discuss the psychology and biology of desire, love and attachment. I explain how childhood attachment types are thought to inform adult attachment styles to romantic partners, and I describe some of the major theories of human mate selection, relationships and infidelity. Additionally, I explore the neurobiology and proposed subconscious processing underlying desire, love and attachment, including the roles of empathy and “positive delusion." I outline how self-awareness can shift one’s relationship attachment style towards securely bonded partnerships. Finally, I describe specific tools and supplements that have been researched to increase libido and sex drive. Throughout the episode, I explain the science and key mechanisms underlying romantic love and outline tools for those seeking to find a strong, healthy relationship, or for those wanting to strengthen an existing relationship.  For the full show notes, visit hubermanlab.com.
