A this tweet went around X this week that's worth taking seriously — not the Bryan Johnson reply-guy joke about firing his blood boy, but the post he was quote-tweeting. Brandon Luu, MD: "Literally just having a delusional golden retriever mindset measurably changes outcomes and physiology."
Tell someone they slept well, and their cognition the next morning measurably improves. Tell them they slept poorly, same. Same body. Different morning. Draganich and Erdal, 2014 proves this.
Every clinician reading this has been having a quieter version of that conversation for years.
The visit you keep having
Your patient walks in and leads with the data: "Recovery's been low all week. My sleep was a 62. HRV crashed Tuesday." Their labs are fine. Their exam is fine. They are not fine.
Ask them how their body actually felt this week, and there's a pause. Then a sentence that translates the question right back into wearable language: "I felt tired. My recovery was probably low." That pause is the whole issue. The device's interpretation now arrives in their brain before their own felt sense does.
Mindset as medicine
The Draganich study (2014) isn't a one-off. The literature on belief as a clinical lever is fifteen years of published research from Ted Kaptchuk's group at Harvard and others:
Open-label placebo trials, where patients are told they're taking a placebo and get better anyway, show measurable effects in IBS (Kaptchuk, 2010), chronic low back pain (2016), migraine (2014), and cancer-related fatigue (2018).
Mindset alone changes the stress response. Crum, Salovey & Achor (2013) showed that telling people stress is enhancing rather than debilitating altered their cortisol response and performance. Same body, different cortisol curve. The only thing that changed was how they thought about it.
Loneliness is more dangerous than obesity or physical inactivity. Across 148 studies, people with strong social ties were 50% more likely to be alive at follow-up than those without (Holt-Lunstad, 2010).
Most of us know this in our bones. We see the patients whose CGM-driven anxiety dissolves the moment they are given permission to stop checking it for a week.
We've been quiet about the power of the placebo effect because saying it out loud sounds soft. The wellness internet spent a decade monetizing the loud, optimization-coded version of care, and the quieter version got crowded out. The Washington Post just published a piece arguing constant-stream wearable data doesn't help most people and produces real anxiety.
What this means for your practice
When wearable data is well-deployed and the patient's relationship to it is calm, it's the promise of personalized medicine actually delivering. When it isn't, the device starts producing the symptom it was supposed to track. There's growing research on cyberchondria (2025), alert fatigue (2025), wearable-induced anxiety (2023), and the disordered-eating risk profile of CGMs in non-diabetic populations (2024).
Your job at this moment isn't to take the wearable away. That's paternalistic and won't work. You also can’t simply deliver a placebo with a wink. Patients feel the wink, and the effect collapses the moment they do.
Your job right now is to be the one stable, evidence-grounded person in your patient's health life. Yes, the labs matter. Yes, the wearable signals matter when used well. And the story your patients tell themselves about their body is itself a treatment. That's the conversation they came to you for.
What to try this week
The single most useful clinical move you can make with a wearable patient in your next visit is to reverse the order of the conversation. Before you look at any data, ask, "Tell me how you actually felt this week. In your body, not on the screen." Sit with the silence. The first answer is usually a translation back into wearable language. Stay in it. Follow up if needed:
"What did your body feel like on the good days?"
"On the days the data said you should feel terrible, how did you actually feel?"
"Has your watch ever contradicted your body? Which did you trust?"
Then bring in the data. Lay the week out next to their felt sense. The teachable moment is in the mismatch. Ninety seconds. Costs nothing. On the Draganich/Erdal logic, the act of asking it is part of the intervention. What your patient comes to believe about their own body's signal-quality is part of the physiology you're treating. This exercise builds interoception, which itself predicts better long-term outcomes.
The bottom line
What your patient believes about their body is as bioactive as anything you prescribe.
Your patient won't clear their shelves, and shouldn't have to. But you can teach them, in ninety seconds, that what they come to believe is itself a treatment. That's the part of the job no algorithm can replace, and the part most of us are quietly best at.

In the news
Parsley Health is the first functional and longevity medicine provider to accept insurance. CEO Robin Berzin announced that its functional medicine services are now in-network and covered for 150 million lives and by all major commercial health plans. The structural implication: insurance-covered functional medicine raises patient expectations and creates a new competitive class for cash-pay practices. Worth watching whether your patients start asking about coverage.
More wearables isn't more medicine. A recent think piece makes the operational case that with consumer devices proliferating at wildly different validation standards, clinical judgment is the filter the industry quietly depends on. You might trust the data. Your patient trusts you.
An AI model outperformed ER doctors at diagnosis — and the researchers are the ones telling you not to over-read the headline. A study published in Science this week from Harvard Medical School and Beth Israel Deaconess found OpenAI's reasoning model matched or beat experienced physicians at diagnosing real ER patients from messy electronic health records. The lead authors went out of their way to caveat the result: none of them believe it supports replacing doctors with AI, "despite what some companies are likely to say and how they're likely to use these results." The takeaway isn't that AI is coming for the diagnosis. It's that AI is finally credible enough to belong in the workflow — under clinical authority, not above it.
The Times asks what could go wrong with AI scribes. Worth reading carefully. About 30% of US doctors are now using AI scribes, and the piece raises the questions our patients are starting to ask: what's stored, for how long, who has access, and how often does the note get it wrong. One cited study found three potentially serious errors per note across five tools tested in simulated encounters. Accuracy gaps are worse for Black patients and non-native English speakers. None of this is a reason to abandon AI scribes — it's a reason to demand the ones that take accuracy, bias, and patient consent seriously, and to keep clinicians firmly in the review loop. The scribe is a draft. The clinician is still the author.
