Now I have a tiny bit of evidence to support that conclusion. What better way to ensure that a scale is valid than by using the standard of concurrent validity (popular in I/O psychology)? This actually happened when renowned Shirley Manson Subject Matter Expert, Shirley Manson, lead singer of the band Garbage, took the "Which Alt-rock Grrrl are you?" quiz and she didn't score as herself (as she posted on Facebook and reported by A.V. Club).

An excellent example of an invalid test (or concurrent validity for you I/O types).
