Friedrich Nietzsche argued that marriage is fundamentally a long conversation, and the key question before committing is whether you can enjoy talking with this person into old age. In this episode, we explore the psychological science behind why conversational compatibility predicts relationship longevity far better than initial passion or shared hobbies. Drawing on research from John Gottman and modern attachment theory, we unpack practical ways to build deeper dialogue, repair communication breakdowns, and create the kind of intellectual intimacy that sustains love for decades.1
