interesting, but i want to nitpick on the appeal to authority: > This fallacy is committed when the person in question is not a legitimate authority on the subject. More formally, if person A is not qualified to make reliable claims in subject S, then the argument will be fallacious. Such arguments are fallacious even when person A is a well informed individual who is sufficiently well qualified to understand the subject. Not recognising this misses the spirit of the fallacy - that all claims must be substantiated and that prior performance is /completely/ irrelevant as to whether any individual claim is valid - even when that experience makes it the case that person A is the foremost expert in the field.
