Lesson
A common bias in analysis is not believing a lie. It is applying a lower evidentiary standard to what you already accept. Rule 9 exists for that reason: no privileged observer, including yourself.
A practical test: write down what evidence would change your mind, then ask whether you would demand that much evidence from the other direction. If the two standards differ, the analysis is not finished.
