Having particular names which may not be in common usage makes it easier for me to identify the things that I've picked up from OB that are now a part of me. Cached Thoughts, Inferential Distance, Mind-Projection Fallacy - those are all terms I use now when referring to things that are a part of me, but not many other people use those terms often. It makes it somewhat easier to identify those things.
I agree. I find it funny that you lead your list of examples with "cached thoughts", because that exactly what these are. Not that that's a bad thing.
If that's the case though, maybe we need to be proactive in preventing them from becoming cached thoughts of the bad kind. Eliezer's posts serve as a good introduction, but I don't think they are the ideal reference. Maybe a rationalist dictionary would do the trick. I envision something like urban dictionary where multiple definition/explanations can be submitted and voted on.

What's the most frequently useful thing you've learned on OB - not the most memorable or most valuable, but the thing you use most often? What influences your behavior, factors in more than one decision? Please give a concrete example if you can. This isn't limited to archetypally "mundane" activities: if your daily life involves difficult research or arguing with philosophers, go ahead and describe that too.
