Process
How to measure stale beliefs about your product in 6 steps
A six-step plan for measuring how many buyers still believe something about your product that stopped being true, using your own changelog as the research instrument. It runs from listing changed facts and checking AI assistants to interviewing recent buyers and tracking a stale-belief rate each quarter. With Koji, every buyer gets the same changelog questions and an AI follow-up when they pick the old value.

What's in this process
- List every changed fact, with dates: Everything about your product that changed in the past 18 months. That list is the whole instrument.
- Ask four AI assistants about each: Record what they say. Facts from training data will be the stubborn ones.
- Interview 30 or more recent buyers: Use your changelog as the question set: the old value, the new value, or not sure.
- Publish the stale-belief rate per fact: Give each of the top three an owner.
- Add one arrival question to the trial: It costs nothing and catches the misconception while the buyer is still reachable.
- Re-run it every quarter: The trend is the point. A single reading tells you little.
