In my business blog today, I got a little, er, hot about tax season. In my footnote, I flamed on about the 2004 elections, noting:

One thing I’m sure of: none of you stopped to analyze the quality of your 2004 decision-making and explicitly change the criteria you used to make your bad decision. It may be 2008, but you’re about to use the same broken decision-making process in November and you’ll wonder why politics doesn’t change.

Political flaming aside, when you make a decision that turns out badly, do you explicitly learn from it? And if so, do you use an explicit “post mortem” process? And do you tend to learn about specifics of a situation (e.g. “I’m never voting for candidate Z again because they lie”), or do you actually change your decision-making process (e.g. “next time, I will look at voting records and read news articles on opposing web sites and supporting web sites before making my decision.”)?

Do you improve your decision quality over time?
