One might think of distrust as the complement of trust, so that if I do not trust you with respect to something, I distrust you. As is implied in the opening paragraph of this chapter, I treat it here rather as the negative of trust. If I trust you, I have specific grounds for the trust. In parallel, if I distrust you, I have specific grounds for the distrust. I could be in a state of such ignorance about you, however, that I neither trust nor distrust you. I may therefore be wary of you until I have better information on you. … Sometimes, I can create the grounds for trust by giving you incentive to be trustworthy.

DEFINE: Distinguishes the negative (opposition) sense of distrust from the complement (simply lacking trust) sense, allowing for a third state of wary ignorance.
