As Mark Twain said: "There are lies, damn lies and statistics."
As an undergraduate, one of the texts we had to read was: "How to lie with statistics".
This is my second-least-favourite famous quote, because it's almost never used to advance any kind of discussion at all.
I'm personally not great at math as an academic subject. I pick up on concepts quickly enough, but I lack the focus and rigor you'd need to effectively do a job like accounting, or to regularly pull off the kind of broad studies that Hockey Outsider does. But I like to think that a working knowledge of a few simple concepts - sample size, the difference between mean and median, stuff like that - and a willingness to ask questions, you can do yourself a favour when you're trying to diagnose what's "wrong" with information you're presented.
"Damn lies and statistics" does none of that, it's just a way to say you don't want to learn anything new and you're proud of it.
But let's not just assume that Mark Twain was a proudly ignorant man, let's do some history.
In his 1906 autobiography, Twain attempts to tally the average number of words per day he was capable of writing as a younger man, and compares his productivity to his more recent projects. This simple bit of arithmetic shows that he's been slowing down considerably in his old age, but he points out almost immediately that he used to pull all-nighters in his more prolific years, spending many hours trying to pound out the 3,000-word sittings he was able to do. He'd later abandon the practice, favouring shorter daytime writing sessions. He concludes that he works more efficiently in his later years, mentions that "figures often beguile me" and then adds the famous quote, attributing it to Benjamin Disraeli.
What I get from that is:
- The main point of the relevant passage is "work smarter, not harder", which is not related to the validity of statistics as a whole.
- Ironically, Twain demonstrates an ability to use statistical inquiry to learn something - he identifies a variable that he hadn't considered (hours worked), and applies it to the question he's trying to answer.
- Twain seems to have a similar relationship with mathematics to the one I described in myself above - interested but skeptical, with a eye on his own limitations.
- The quotation itself may have come from a politician. It looks like there isn't actually a record of Disraeli saying that. If Disraeli did in fact coin the phrase, it's easy to see how it could be weaponized against his opponents in the same ignorant, dismissive fashion most use it today. But we don't know that, or what its original context is.
