What the research can actually carry.
A plain-language takeaway with its limits intact—not science as decoration.
What this guide is
A library of reasons, not a shelf of links.
Every finished entry makes the case in plain language: what is known, what is not settled, who may want to pause, and what the real cost is if the product does nothing. An optional partner link, if one ever appears, comes after the full explanation and stays visibly separate from it.
The entry standard
What a finished card has to show.
Who may fit and who should pause.
General context, not personal diagnosis, plus a clear reason to step back when needed.
The price of being wrong.
Money, time, subscription friction, risk, and the ordinary alternative are part of the answer.
