The easiest way to filter out 99 percent of this is to ignore anything that has no impact on your life (ie doesn't pay rent).

Eh? If I was renting, I think that would have an impact on my life -- so maybe this is yet another metaphor I never heard of.

If everyone was processing reality to the best of their analytical (and other) abilities, and honestly passing on the conclusions they reach then virtuosity at recognizing rational fallacies would go a lot further than I think it actually does; I'm afraid much of what we need is a social understanding of others.

Just FWIW, Aspergers types, which many I encounter here are self-proclaimed to be, have a chance to do this better than other people, because they have to do consciously what others have no idea that they're doing. By the way, book recommendation: The Journal of Best Practices by David Finch. Very funny and enlightening, about an Aspergers/non-Aspergers mixed marriage. My wife and I had a good time reading it.
