 Philosophers sometimes ask whether it could ever be rational to trust other people. This question arises for two reasons. First, it appears that trust and rational reflection (e.g., on whether one should be trusting) are in tension with one another. Since trust inherently involves risk, any attempt to eliminate that risk through rational reflection could eliminate one’s trust by turning one’s stance into mere reliance. Second, trust tends to give us blinkered vision: it makes us resistant to evidence that may contradict our optimism about the trustee (Baker 1987; Jones 1996 and 2019). For example, if I trust my brother not to harm anyone, I will resist the truth of any evidence to the contrary. Here, trust and rationality seem to come apart.
