“You are the most relevant sample size of one. The study was done on someone else.”

Population research gives you priors, not conclusions. Your experiment gives you a verdict that no study ever could: how this specific intervention lands in your specific biology, life context, and psychology. That data is irreplaceable.

“A baseline is not prep work. It is the most important data you will collect.”

Without knowing where you started, you cannot know where you landed. Seven days of honest measurement — before anything changes — transforms your experiment from anecdote to evidence. Most people skip this step. Don't.

“Compliance rate is your experimental variable. If you did not follow the protocol, you did not run the experiment.”

A 70% compliance rate means you spent 30% of the experiment doing something else. The results tell you how your irregular, partial version of the intervention affected you — not whether the original protocol works. Track adherence first.

“Effect size is not a success metric. It is a truth metric.”

A small effect size does not mean the experiment failed. It means the intervention has a small effect on you. That is precisely the answer you came for. A clear 'this doesn't move me' is more valuable than a blurry 'might be working.'

“The goal is not to prove the book right. The goal is to know the truth about yourself.”

Many people run self-experiments hoping to confirm what they already believe. Honest science requires equal willingness to get a null result. A null result is not failure — it is calibration. You are removing a false belief from your operating system.

“Archive, adopt, or retest — three verdicts that replace 'I should probably do this someday.'”

The lab closes when you render a verdict. Archive means: this intervention is real and interesting, but not for you right now. Adopt means: the evidence is strong enough to make this permanent. Retest means: promising signal, different conditions needed.
