How to use it
For a task you dread: rate how much you want to do it, 0–10, then ask why it isn't lower. That answer is your reason. Say it to someone. Ask a stuck person the same two questions instead of telling them why.
How sure we are
S Evidence: strong. Large trials or many studies, pointing the same way.
P Evidence: promising. Good studies, but small or few. Use it and keep checking.
