 In talking about the construction of representations, we address the range of mental states, group beliefs, scientific theories, and other representations that express concepts or propositions. Such representations are, among other things, the vehicles of our thought as well as the means by which we store, organize, and further our knowledge of the world, and we do this in virtue of their role as bearers of meaning. A number of commentators have noted that many provocative constructionist claims are, in the first instance, claims that some sort of representation is constructed (e.g. Andreasen 1998, Hacking 1999, Haslanger 2012, Mallon 2004). Specifically, these are claims that social causes produce or control the selection of some representations with some meanings rather than others: for example, when Pickering (1984) writes of the construction of quarks or Laqueur (1990) suggests that sex is “made up,” they seem to be most directly addressing the process by which the theories of the quark or theories of sex are produced, viz. they are showing how a theory with one meaning was selected or endorsed rather than another theory or no theory at all. Where we limit the objects of constructionist claims to representations (such as theories), the claims cease to be particularly metaphysically provocative though detailed constructionist accounts of how certain representations came to be selected may still teach us much about science (e.g. Latour and Woolgar 1979l Collins and Pinch 2012).
