The Proof Loop is a four-step behavior-change method — Shrink, Act, Bank, Repeat — created by Sullivan J. Ryan, Ph.D., and published in full in the book Prove It to Yourself.
Ryan writes field guides for people living inside systems that were not designed with them in mind. All of the work sits at one intersection: how humans interact with complex systems, and how those systems quietly shape behavior. Whether the system is an algorithm, an institution, or the wiring inside your own head, the method is the same — open the machinery, name the incentives, hand the controls back to the reader. Other books include Factory Reset, Root Access, The Fine Print of the PhD, and When to Trust AI (and When Not To), all at sullivanjryan.com.
What this site is
The canonical home of the Proof Loop: the complete guide, free tools, and the printable journal. The method is given away in full here on purpose — it costs a notebook, and a method about evidence should be checkable before anyone spends a dollar on it.
