I've seen no evidence to convince me that my statement is not accurate.
Absence of evidence is not evidence of absence.
I love how quoting the first rule you learn in every university science course ended got replies about how unscientific it was, in so many words.
And I love how people, deliberately or not, will twist the meaning of other people's words just so they can fit a pithy saying into their rebuttals.
Now, personally, one of the first things
I learned in science class is that if repeated trials support a hypotheses, that hypotheses can be treated as true until new evidence disproves it... and consistent results, whether through experimentation or empirical observation, generally get categorized as "evidence".
Glor's empirical observations (apparently) support a theory that players that fall into a group he has labeled "munchkins" make poor GMs and will try to skew play in favor of their own characters if given the chance. Lack of anything contraindicating that theory is not an "absence of evidence." It's an "absence of
contradictory evidence"... which is an entirely different kettle of fish.
