Quantum mechanics notoriously faces the measurement problem, the problem thatif read thoroughly, it implies the nonexistence of definite outcomes inmeasurement procedures. A plausible reaction to this and to related problems isto regard a system's quantum state $|\psi\rangle$ merely as an indication ofour lack of knowledge about the system, i.e., to interpret it epistemically.However, there are radically different ways to spell out such an epistemic viewof the quantum state. We here investigate recent developments in the branchthat introduces hidden variables $\lambda$ in addition to the quantum state$|\psi\rangle$ and has its roots in Einstein's views. In particular, weconfront purported achievements of a concrete model that has been considered toserve as evidence for an epistemic view of the envisioned kind, as well asspecific no-go results and their import. It will be argued that while anepistemic account of the particular kind is not straightforwardly ruled out bythe no-go results, they demonstrate that the evidential character of themodel(s) discussed rests on a rather shaky foundation, and that they make someachievements widely recognized in the literature appear worthy of doubt.
