 List and Pettit (2011), as we saw in Section 2, make clear that holding groups responsible for particular kinds of harm not only “lets us discern the true contours of the moral and political world we inhabit” (List and Pettit 2011, p. 185), but provides incentives for change among group members (p. 168), and conditions them to behave better in the future (p. 157). Likewise, it can provide the basis for institutional reform in cases where collective acts were hitherto invisible.
