Steven Novella of The Skeptics' Guide to the Universe podcast back in 2008 attempted to make a consice definition of scientific skepticism. When googling around, it appears to have become informally rather widespread. What do you think about it?

Steven Novella said:A skeptic is one who prefers beliefs and conclusions that are reliable and valid to ones that are comforting or convenient, and therefore rigorously and openly applies the methods of science and reason to all empirical claims, especially their own. A skeptic provisionally proportions acceptance of any claim to valid logic and a fair and thorough assessment of available evidence, and studies the pitfalls of human reason and the mechanisms of deception so as to avoid being deceived by others or themselves. Skepticism values method over any particular conclusion.
