I am delighted to report that the economics paper on AC/DC I blogged about yesterday was meant as a joke. It takes a lot of work to run an experiment on real people, just for a gag paper. It turns out they meant to play the same AC/DC song in both treatments, but made a mistake and accidentally played two different songs. Thus the genesis of the joke paper.
I still think this leaves Professor Oxoby with a bit of explaining to do as to why they were playing AC/DC as part of an experiment in the first place, however.
