 In discussing the rationality of trust, some authors distinguish between these two types of rationality (also referred to as epistemic vs. strategic rationality; see, e.g., Baker 1987). One could say that we are rational in trusting emergency room physicians, for example, not necessarily because we have good reason to believe that they are trustworthy (our rationality is not truth-directed), but because by trusting them, we can remain calm in a situation over which we have little control (our rationality is therefore end-directed). Similarly, it may be rational for me to trust my brother not because I have good evidence of his trustworthiness but rather because trusting him is essential to our having a loving  relationship.[10]
