Your phrase "Compelling anecdotal evidence is an oxymoron" seems strange. If 5 people told me they saw my wallet outside, I'd be compelled to check, by anecdote, if I'd dropped it on my way in.
Compelling anecdotal evidence is an oxymoron, especially when the scientific evidence to the contrary is so strong.
