This is great.
A point which helped me understand number 6: If you ask someone “why do you believe X”, since you’re presumably going to update your probability of X upwards if they give a reason, you should update downwards if they don’t give a reason. But you probably already updated upwards as soon as they said “I believe X”, and there is no theorem which says this update has to be smaller than the latter update. So you can still end up with a higher or equal probability of X compared to where you were at the beginning of the conversation.
