About this episode
In this episode of Fighting Matters, Steve Kwan and Stephan Kesting are joined by scientist and author Kristi Charish to investigate how Jiu-Jitsu became a hotbed for pseudoscience, supplement scams, and influencer grifts. We explore how a culture of male insecurity and anti-intellectualism has opened the floodgates to misinformation—fueled by algorithm-chasing gurus and podcast personalities more interested in profit than truth. From testosterone fads and supplement sponsors to sunning your testicles (yes, really), we unpack the deep societal forces that make grapplers uniquely vulnerable to snake oil. If you’ve ever been told that breathing through one nostril will double your growth hormone, this episode is for you. ⸻ 👥 Featuring: Kristi Charish – Scientist & Novelist Stephan Kesting @StephanKesting Steve Kwan @bjjmentalmodels ⸻ 🧠 Topics We Cover: • Why Jiu-Jitsu is especially vulnerable to pseudoscience • The myth of the supplement “quick fix” • How science actually works (and why grifters hate it) • Why confidence sells better than expertise • The parasocial trap of podcast influencers • What “adaptogens” actually mean (hint: nothing) ⸻ 📖 Chapters: 00:00 Introduction and Guest Introduction 01:06 Kristi's Science Background and Transition to Fiction 04:25 The Challenge of Science Misinformation 10:03 The Role of Influencers in Misinformation 16:02 Regulation of Supplements vs. Prescription Drugs 24:03 Understanding Scientific Research and Publication 38:32 The Nature of Expertise and Certainty in Science 46:54 The Risks of Superfoods and Supplements 48:46 Trust in Science and Misinformation 50:19 The Dangers of Distrust in Institutions 53:13 The Impact of Influencers on Health Perception 01:02:47 Misinformation Targeting Young Men 01:09:44 The Dangers of Male Beauty Standards 01:19:27 Improving Science Literacy in Society
