4. Social trust and reputation
Reputation: perception that an agent creates through past actions
Trust: subjective expectation an agent has about another’s future behavior
based on the history of their encounters
Difference between trust and reputation
1. “I trust you because of your good reputation.”
2. “I trust you despite your bad reputation.”

and Social Networks", 2003, Ph.D. Dissertation, Massachusetts Institute of Technology
