Took the survey. I definitely did have an IQ test when I was a kid, but I don't think anyone ever told me the results and if they did I sure don't remember it.

Also, as a scientist I counted my various research techniques as new methods that help make my beliefs more accurate, which means I put something like 2/day for trying them and 1/week for them working. In hindsight I'm guessing this interpretation is not what you meant, and that science in general might count as ONE method altogether.
