So, what’s the deal with chiropractors? Are they all just full of it? Ian Kaplan is the COO of Hybrid Performance Method (Stefi Cohen’s training company) and soon to be doctor of chiropractic, and he’s also one of the most thoughtful and skeptical people in the fitness space. In this conversation, Ian breaks down how he thinks about uncertainty and providing treatment options when a lot of the research shows that most things that we talk about in the fitness and rehab space - well - don’t actually work. He also lays into some of the most common issues he sees with other chiros. And, of course, we spend awhile getting into the weeds and discussing pain science, Bayesian reasoning, and the future of artificial intelligence in guiding treatment protocols.

Check out the full conversation with Ian if you want to hear two dorks talk about things like "epistemic humility" - or if you want to hear one of the smartest fellas in fitness explain how he thinks about pain.

Show Notes: [01:04] Ian’s beefs with the field of chiropractic – and what it means to be “evidence-based” in a field with so much uncertainty. [11:50] How should someone actually think about treatment given the inherent uncertainty in dealing with complex systems? How does Ian weigh the costs and benefits of a potential treatment? [18:46] Why are clinicians so easy to fool: regression toward the mean and threshold effects. And, how to give patients hope without lying to them. [25:46] Is it better to try to treat pain with targeted tissue interventions or is it better to focus on the brain? [33:31] The role of artificial intelligence in developing precision medicine models for treating pain patients [39:51] What are the barriers to effectively analyzing treatment data from chiropractors and physical therapists? [44:50] A brief summary of Bayesian inference and its value for treatments, pain science and making business decisions [56:56] How does Ian think about Bayesian inference as a unifying principle for weird stuff we see in pain science like placebo effects and extreme pain sensitivity [01:07:54] How to check out more from Ian Links and Resources Mentioned Humorism What’s the Difference Between a “Straight” Chiropractor and a “Mixer”? from Gutierrez Chiropractic Sensitivity and specificity Threshold effect Opportunity cost Regression toward the mean Bean machine “Arthroscopic Partial Meniscectomy versus Sham Surgery for a Degenerative Meniscal Tear” from the New England Journal of Medicine “Null hypothesis significance testing: A short tutorial” from F1000 Research Confidence interval “Learn About Lookalike Audiences” from Facebook Tempus Externality Introduction to Bayesian networks Information theory “The Bayesian brain: the role of uncertainty in neural coding and computation” from CellPress Frequentist probability “Frequentist And Bayesian Approaches In Statistics” from Probabilistic World “How to take the ‘outside view’” from McKinsey “The Book of Why: The New Science of Cause and Effect” by Judea Pearl Neural network “To Make Sense of the Present, Brains May Predict the Future” from Quanta Magazine Greg Lehman
