People who don't want to disappoint you and that are prone to guilt if things go wrong are the least likely to want to commit to a project - but they may be who you want on your team, because if they do commit, that propensity for feeling guilty if they let down the team makes them among the most ethical and hard-working partners, according to management academics.

In a proper mix, highly guilt-prone people (i.e., people with a strong dispositional tendency to feel guilty for wrongdoings) make valuable work partners because a concern about letting others down drives them to complete at least their fair share of the work. 

"Because of this concern for the impact of their actions on others' welfare, highly guilt-prone people often outwork their less guilt-prone colleagues, demonstrate more effective leadership and contribute more to the success of the teams and partnerships in which they are involved," according to Scott S. Wiltermuth, assistant professor of management and organization at the USC Marshall School of Business.

Because of that, getting such individuals to enter into certain partnerships at work can be difficult. 

In five studies, Wiltermuth and Cohen demonstrated that highly guilt-prone people may avoid forming interdependent partnerships with people they perceive to be more competent than themselves, because benefiting a partner less than the partner benefits them could trigger feelings of guilt.

"It may come as a surprise," Wiltermuth said, "but our findings demonstrate that people who lack competence may not always seek out competence in others when choosing work partners."

In studies where Wiltermuth asked participants with whom they would like to partner to complete a task, given information about their potential partners' expertise in that area, highly guilt-prone people with less knowledge or skill in that area were less likely to choose the most competent partner. They were afraid to contribute less to the task than their partner and, thus, let them down.

In the studies, highly guilt-prone people were also more likely than others to opt to be paid on their performance alone and to opt to be paid based on the average of their performance and that of others whose competence was more similar to their own.

"Guilt proneness reduces the incidence of unethical behavior," Wiltermuth said. "Highly guilt-prone people are conscientious. They are less likely to free-ride on others' expertise, and they will sacrifice financial gain out of concern about how their actions would influence others' welfare."

Those in supervisory roles can use this research to create the most effective dynamics in the workplace and increase productivity.

"Managers could try to ensure that highly guilt-prone people are creating the partnerships and perhaps even assuming leadership roles on teams," Wiltermuth said, "despite highly guilt-prone people's fear that by accepting these leadership positions they might be putting themselves into position to let their teammates down."
