Why A Sustainable Performance Physician Holds Coaching to a Fiduciary Standard, and Not a Research Standard

Best interest and maximum evidence are not the same thing. Past a certain point, they pull in opposite directions.

Demanding a perfect study for every coaching intervention sounds rigorous. It is not.

What does fiduciary actually mean?

It means acting in the other person's best interest. Not your own, not the appearance of rigor, theirs.

That is the standard a physician already lives under. It is also the standard almost no one in the coaching industry has even attempted to define.

Is more evidence always better?

No. This is the part most people get backwards.

Restricting yourself to only heavily-proven methods sounds like the responsible choice. In practice it strips out the patient-to-patient variation that individualized care depends on, and it forces a false uniformity onto tools that are supposed to flex.

An over-strict evidence bar is itself a fiduciary failure. It serves the appearance of rigor at the cost of the patient.

Is this just an excuse to skip the research?

No, and the distinction is the whole point.

A physician recommends things every day that have a plausible mechanism and clinical experience behind them, without a dedicated trial proving that exact intervention in that exact patient. That is not a weakness to hide. That is what practicing medicine actually is.

The fiduciary standard does not mean “I found a perfect study for everything.” It means “everything I recommend is grounded in real science and real patient care, and I will tell you which is which.”

What does honest labeling look like?

Every recommendation carries a stated mechanism. Where a real study supports that mechanism, it is cited. Where the support is a plausible mechanism plus clinical use, the record says exactly that, in plain language.

A reader always knows whether they are looking at a validated mechanism or a clinically reasoned one. Nothing gets dressed up as more than it is.

This is not a softer standard. It is a more honest one.

Does honest labeling make you easier to attack?

It does the opposite. It removes the only real vulnerability.

If someone says a study does not perfectly prove a given method, the honest record already said that. You never claimed it did. The person is arguing against a claim that was never made.

The vulnerability only exists when you overclaim. Label accurately and the attack has nowhere to land.

Why does this matter for coaching specifically?

Because most performance interventions are simple behavioral interrupts, not delivered therapy. They are high user-dependence by design. The same tool lands differently for different people in different states.

Demanding study-level precision on a tool whose entire nature is individual variability is a category error. A breathing protocol with a fixed physiological mechanism tolerates a tight claim. A reset ritual or an identity cue works through the person, not on the person, and the honest claim for those is mechanism-plausible and clinically used.

Knowing which one is which is clinical judgment. That judgment is the product.

The SPMD Standing Challenge

I am happy to entertain critique from any other coach the moment they can cite a plausible underlying mechanism for the interventions, interrupts, behavioral modifications, unsupported techniques like NLP, and the supplements they sell without good evidence.

No one else in this space has even tried to collect all of that for all of their products and programs.

So I am building it here with SPMD.

I look forward to the day when anyone else builds something similar to SPMD and wants to challenge our methods with their own, holding us both to the same level of real clinical evidence. I will be the first to engage them seriously, and happy to do so.
