I don’t know how to port this strategy over to verbal acuity for rationality.
Perhaps by vocalising simple logic? When you make a simple decision, such as “I’m going to walk to work today instead of catching the bus”, go over your logic for the decision, even after you’ve started walking, as if you’re explaining your decision to someone else. I often do this (not out loud, but as a mental conversation), just for something to pass the time, and I find that it actually helps me organise my thoughts and explain my logic to other real people.
