By heuristic based processing, as with how I do most things. It seems reasonable to assume that the same isn't true of you, though, so I expected a rather more useful answer to my question. (Relevant heuristics include 'if confused, ask for information' and 'alert friend-type people to mistakes so that they can avoid those mistakes in the future'.)

I also use heuristic reasoning, (governed by the meta-heuristic of correct reasoning), and here I thought that User:David_Gerard was significantly overstating the risks of sewer-diving and Scientology classes for humans. Therefore, I added my "independent component" to the discussion.
