Interest in the topic of trust both within and between organizations has grown greatly in recent years. One key issue to understanding trust and how it can be more effectively fostered is understanding its causes. Based on the 1995 Mayer, Davis, & Schoorman model of trust, this article describes exercises that allow students to inductively discover the importance of a trustee's ability, benevolence, and integrity to the assessment of trustworthiness. Parallel exercises are described that can be used to teach both trust between people and trust between organizations. (Contains 2 tables and 1 note.)
