Guide — Reading Against Yourself
Two mechanisms make an invested reader worse at reading than an uninvested one, and neither involves any dishonesty. The third card is the only technique with a real record against them.
Committed Course
Accident investigators in marine and aviation work have a term for this: plan continuation. A course is laid, the passage begins, and information suggesting the plan is wrong arrives — and is explained away rather than acted on. The further into the plan, the harder the resistance, which is exactly backwards from what the situation requires.
Everything in this series so far has assumed a reader weighing evidence from a standing start. Most people are not doing that. They are already six months into a bottle, they have spent a few hundred pounds, they told a friend about it, and now they are reading. That reader is not evaluating the evidence; they are defending a position, and they will not experience it that way.
The mechanism is asymmetric scrutiny, and it is nearly invisible from inside. Evidence that agrees gets read once and accepted. Evidence that disagrees gets examined for flaws — and since every study has flaws, the examination always succeeds. Nobody in this process lies to themselves; they simply apply a higher standard in one direction. This guide covers how that works, why sunk cost sharpens it in this particular market, and the one technique with any real track record against it.
The first two operate on you. The third is what to do about them.
The guide covers why this feels like being careful rather than being biased, and the specific tell: noticing that you have only ever gone looking for methodological problems in one direction.
The honest complication: scrutiny is genuinely valuable, and the answer is not to stop scrutinising. It is to apply the same effort to the study you liked, which almost nobody does and which is the whole of the technique.
This market is unusually exposed to it: a monthly purchase, a long horizon before any effect would be visible, and no clear signal that would ever tell you to stop. The guide covers why those three features combine badly.
The reframing that works: the only question is whether the next purchase is worth its own price. What earlier purchases cost is settled and cannot be improved by any decision now available to you.
This is the same discipline that trial pre-registration exists to enforce, applied to a personal decision. The guide covers how to write one usefully, how specific it needs to be, and why vague versions fail.
The honest limit: it works imperfectly and it feels unnecessary at the time, which is why almost nobody does it. It is still the best available, and it costs five minutes before rather than an argument with yourself afterwards.

Notice: This is not a medical portal and provides no diagnostic or treatment service. What is sold here is education about reasoning under commitment. It names no brand and endorses no product. The bias it describes applies to purchases you talked yourself into, not to advice a clinician gave you — treating those alike would invert the whole argument. If reading this makes you want to stop something prescribed, that is a reason to call your doctor rather than to act. If you have symptoms, pain, or any concern, book an appointment.
