 By contrast, Victoria McGeer believes that trust is more substantial or pure when the available evidence does not support it (2008). She describes how trust of this sort—what she calls “substantial trust”—could be rational and does so without appealing to how important it might be or to the ends it might serve, but instead to whether the trustee will be  trustworthy.[11]  According to McGeer, what makes “substantial trust” rational is that it involves hope that the trustees will do what they are trusted to do, which “can have a galvanizing effect on how [they] see themselves, as trustors avowedly do, in the fullness of their potential” (2008: 252; see also McGeer and Pettit 2017). Rather than complain (as Hieronymi would assume that trustees might) about trustors being merely hopeful about their trustworthiness, they could respond well to the trustors’ attitude toward them. Moreover, if it is likely that they will respond well—in other words, that they will be trust-responsive—then the trust in them must be epistemically rational. That is particularly true if being trustworthy involves being trust-responsive, as it does for McGeer (McGeer and Pettit 2017).
