The post explores how emotional learning creates hard-to-update mental models, drawing parallels between psychotherapy, psychedelics, and rationality techniques in overcoming these 'mental mountains'. Longer summary

This post discusses the book 'Unlocking The Emotional Brain' (UtEB) and its implications for understanding biases and mental processes. The author explores how emotional learning creates unconscious predictive models that guide behavior, and how these models can be difficult to update even in the face of contradictory evidence. The post draws parallels between UtEB's approach, psychedelic therapy, and rationality techniques, suggesting that they all aim to overcome mental 'mountains' that separate different areas of knowledge or belief. The author proposes that these mental separations might be a necessary feature of how our brains generalize from experiences, but can also lead to problems like cognitive biases and psychiatric symptoms. The post concludes by considering how this framework might help understand and address deeply held but irrational beliefs. Shorter summary
