In the season finale of How Humans Talk, Rune Pedersen turns the microphone inward to explore one of the most personal forms of communication: how we talk to ourselves. From spirals of doubt to pep talk, inner monologues shape our sense of self and how we move through the world. Psychologist Dr. Chris Cheers helps untangle the threads of self-talk, rumination, and childhood schemas, revealing how our internal narratives can support or sabotage us. Rune also speaks with Corinne Ooms from Alone Australia, who recounts the profound shift in her self-perception after spending seventy days in complete isolation. And poet Thabani Tshuma invites us into the transformative space of language and recovery, where self-talk becomes both survival and art. Together, they explore how changing the voice in your head can change everything.
