  The main claim of the paper is that one can be 'realist' (in some sense)
about quantum mechanics without requiring any form of realism about the wave
function. We begin by discussing various forms of realism about the wave
function, namely Albert's configuration-space realism, Duerr Zanghi and
Goldstein's nomological realism about the wave function, Esfeld's dispositional
reading of the wave function and Pusey Barrett and Rudolph's realism about the
quantum state. By discussing the articulation of these four positions, and
their interrelation, we conclude that instrumentalism about the wave function
is by itself not sufficient to choose one over the other interpretations of
quantum mechanics, thereby confirming in a different way the indetermination of
the metaphysical interpretations of quantum mechanics.
