This week, we're joined by Nick Salles! Nick is a black belt under Mikey Musumeci and co-founder of Movement Art Jiu-Jitsu. In this episode, Nick discusses epistemic humility: a scientific philosophy reminding us that our knowledge is always incomplete. Topics include: democratic learning environments, creating conditions for exploration, constraints-led training, recoverable vs. unrecoverable errors, gym culture, and the limits of AI in skill acquisition.
