 Others say that reasons for trust are usually too numerous and varied to be open to the conscious consideration of the trustor (e.g., Baier 1986). There can be very subtle reasons to trust or distrust someone—for example, reasons that have to do with body language, with systematic yet veiled forms of oppression, or with a complicated history of trusting others about which one can’t easily generalize. Factors like these can influence trustors without them knowing it, sometimes making their trust irrational (e.g., because it is informed by oppressive biases), and other times making it rational.
