Yeah, yeah, and GLOWBULL WARMING is rewally "real", you can change your sex just by saying so, or lopping off/adding some body part, and if you really, really, REALLY believe that you are a member of the Negroid race, even though you are a blue eyed blonde with stick straight hair, skin the color of skim milk, and nary a Negroid marker in your DNA, then of course you are a "black" person! /s
I can guarantee whomever did this study, that my memory is superior to theirs and my 50s is in my past!
