Unfair rating attacks to trust systems can affect the accuracy of trust evaluation when trust ratings (recommendations) about trustee agents are sought by truster agents from others (advisor agents). A robust trust system should remain accurate, even under the worst-case attacks which yield the least useful recommendations. In this work, we base on information theory to quantify the utility of ...

After a trust violation, some people are quick to forgive, whereas others never trust again. In this report, we identify a key characteristic that moderates trust recovery: implicit beliefs of moral character. Individuals who believe that moral character can change over time (incremental beliefs) are more likely to trust their counterpart following an apology and trustworthy behavior than are i...

In this paper we explored the effects of exposure to images of the suffering and vulnerability of others on altruistic, trust-based, and reciprocated incentivized economic decisions, accounting for differences in participants' dispositional empathy and reported in-group trust for their recipient(s). This was done using a pictorial priming task, framed as a memory test, and a triadic economic ga...
