BEHOLD, REIFICATION!
In the comments below Antonio pointed me to this working paper, What Do DNA Ancestry Tests Reveal About Americans’ Identity? Examining Public Opinion on Race and Genomics. I am perhaps being a bit dull but I can't figure where its latest version is found online (I stumbled upon what looks like another working paper version on one of the authors' websites). Here's the abstract:
