The first chapter of Michalos' "Improving Your Reasoning" ends with the following:

"The question is: Will you study logic in order to learn more about this tool [logic] you have been using for years and will continue to use? Or, will you ignore the study of logic and continue to use it anyhow? The choice is yours. So are the consequences. (That is supposed to sound threatening.)"

What heuristics, techniques, and questions do you use to untangle or cut through complexity?

I've found that studying logical fallacies naturally helps me to detect them more readily, but given the complexity of the world, I often wonder what it would look / feel like to reach a level where one's reasoning and speech is 100% consistent and correct (given the perceived facts).
