 Thin constructivism depicts race as a grouping of humans according to ancestry and genetically insignificant, “superficial properties that are prototypically linked with race,” such as skin tone, hair color and hair texture (Mallon 2006, 534). In this way, thin constructivists such as Robert Gooding-Williams (1998), Lucius Outlaw (1990, 1996) and Charles Mills (1998) rely on the widespread folk theory of race while rejecting its scientific foundation upon racial naturalism. Interactive kind constructivism goes further, in arguing that being ascribed to a certain racial category causes the individuals so labeled to have certain common experiences (Mallon 2006, 535; Piper 1992). For instance, if society ascribes you as black, you are likely to experience difficulty hailing cabs in New York or are more likely to be apprehended without cause by the police (James 2004, 17). Finally, institutional constructivism emphasizes race as a social institution, whose character is specific to the society in which it is embedded and thus cannot be applied across cultures or historical epochs (Mallon 2006, 536). Michael Root (2000, 632) notes that a person ascribed as Black in the United States would likely not be considered Black in Brazil, since each country has very different social institutions regarding the division of humanity into distinct races. Similarly, Paul Taylor (2000) responds to Appiah’s racial skepticism by holding that races, even if biologically unreal, remain real social objects (Mallon 2006, 536–537). Indeed, in a later work Taylor (2004) argues that the term “race” has a perfectly clear referent, that being those people socially ascribed to certain racial categories within the United States, regardless of the widespread social rejection of biological racial naturalism.
