I would classify Scott Adam's statement as a trueism -- true for most people, under most circumstances, for most times. Unfortunately, couching a trueism in its most precise linguistic form with associated probabilities and error margins is a path to simply being ignored. Once a thread switches to rhetoric, dialectic responses are like pissing in the wind, forgive the analogy :-)

Well I’ll give you this: quoting Scott Adams then correctly using and understanding the word dialectic is definitely not on my HN comment threads bingo card.
