 Some representations are accurate; others aren’t. The quantum mechanical model is an accurate representation of the atom (at least by our current lights) but the Thomson model isn’t. On what grounds do we make such judgments? Morrison (2008: 70) reminds us that it is a task for theory of representation to identify what constitutes an accurate representation. We call this the problem of Standards of Accuracy. Providing such standards is one of the issues an account of representation has to address, which, however, is not to say that accurate representation is the sole epistemic virtue of scientific models. As Parker (2020) points out, there are numerous of considerations to take into account when evaluating a model’s adequacy for its purpose, see Downes (2021: ch. 5) for further discussion.
