I don't think I rationalize to any significant extent. Even the examples I came up with for Anna's thread concern inefficient allocation of attention and using zero-information arguments, not something specifically directed to defense of a position. I admit being wrong or confused on simple things, sometimes incorrectly (so that I have to go back to embrace a momentarily-rejected position). It's possible I'm completely incapable of noticing rationalization and would need a new basic skill to fix that, but doesn't seem very likely.

(Alternatively, perhaps "rationalization" needs to be unpacked a bit, so that problems like those in the examples I referred to above can find a place in that notion. As it is, they seem more like flaws in understanding unbiased with respect to a favored conclusion, unless that conclusion is to be selected in the hindsight.)
