I hope one of the questions is: Do you use the word "garner"?
Just kidding. I took Murray's test. According to the above-quoted Washington Post story ("The most out-of-touch places in America"):
Scores range from from 0–100, a full score meaning that someone is completely in tune with working-class culture. Perhaps not surprisingly, the Newshour audience is largely composed of fancy people. The median score was around 40 out of 100.I got a 20.
Take the test here.
