If we had topic-headings here, I'd be suggesting a new one: I changed my mind today.
Being rational is all about chainging your mind, right? It's about re-assessing in the face of some new evidence. About examining the difference between your assumptions and the world itself. Narrowing down the difference between the model and the reality, the map and the territory.
Maybe your 'karma' should reflect how much you've told us when you changed your mind? Certainly I'd like to know when people change their minds about things more than when they just agree with me.
In fact, I think that is probably the thing I most want to know about from any of the people whom I know primarily because of their professed rationality.
Especially if they explain why they changed their minds, and do it well.
With that in mind, and introducing the new acronym: ICMMT
I Changed My Mind Today!
Or at least I revised my opinion.
