Hosted by Rachel Feltman
Written by a model from the transcript; not yet reviewed.
In this episode, host Rachel Feltman and guests Lauren Leffler and Adam Conover explore three unusual topics ranging from historical science myths to modern psychological data. The discussion covers the history of human spontaneous combustion—tracing how a pseudo-scientific belief popularized by Charles Dickens persisted despite scientific reality—alongside recent forensic research on bone density and the wick effect. The conversation also investigates the sleep-wake transition known as N1 sleep, examining how micro-naps and hypnagogia might foster creativity and problem-solving, and finishes with an analysis of survey data surrounding male sexuality, performance anxiety, and the lack of cultural self-examination among straight men.
