I find it interpersonally very helpful, because I might have a thought about someone I am with. The other day I met someone for the first time, in an unusual situation. Given the context and something about the how that person appeared to me, I had a predisposition or bias to a certain stereotype. "Oh, this is that kind of person." Because I have a practice of watching my thoughts arise, I could see that thought arise. Immediately I knew, "Oh Gil, this is just your thought. This is your interpretation of the situation. You better stay open here to find out, what's really going on here with this person. Who this person is." In fact, very quickly, I came to see this person was not my stereotype, not what I thought.
