 Secondly, as noted in  Section 1,  allowing for the possibility of misrepresentation is a key desiderata required of any account of scientific representation. In the context of a similarity conception it would seem that a misrepresentation is one that portrays its target as having properties that are not similar in the relevant respects and to the relevant degree to the true properties of the target. But then, on Similarity 2, \(M\) is not a representation at all. The account thus has difficulty distinguishing between misrepresentation and non-representation (Suárez 2003: 233–235).
