With respect to that Twain/Disraeli quote, my friend who is a professor of statistics tells me that he cannot go to a party and say what he does for a living without someone repeating it smirkingly.
The irony of people who use the "damned lies and statistics" quote snidely is that the "statistics" part is not referring to the field Statistics but the plural version of the noun statistics, which of course are easily abused. The field of Statistics is all about NOT abusing statistics.
Yeah, it always makes me wonder when they have to put the "science" in the name. "Computation" seems so much more timeless and elegant than "computer science", for instance. It's almost like "Democratic Republic" for nations.
