 First, differences in responses may be produced by different ways of “filling in” a schematic hypothetical case (Sosa 2007; Horvath 2015). Second, there may be multiple concepts answering to a single word (Sosa 2007). (For some recognition of this fact by experimental philosophers, see the use of the “coin-flipping” case by Weinberg et al. (2001) and Swain et al. (2008) to exclude subjects who use “S knows that p” to mean merely that S has high confidence that p.) These two suggestions do not raise the possibility that that the subjects in such surveys are not responding on the basis of intuitions. Rather, they raise the possibility that the intuitions are not intuitions regarding the same property or about the same case. (See Alexander and Weinberg 2007 for the suggestion that both of these concerns apply equally to non-solipsistic proponents of the traditional armchair methodology.)
