Keno Juechems is a Junior Research Fellow at St John's College in Oxford. He studies how humans make decisions, using computational modelling, behavioural tasks, and fMRI. In this conversation, we talk about his papers  "Optimal utility and probability functions for agents with finite computational precision" and  "Where does value come from?", and various related topics.

BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith. New episodes every Friday. You can find the podcast on all podcasting platforms (e.g., Spotify, Apple/Google Podcasts, etc.).
