Because only one standard exists, each student knows the guidelines and expectations to which he must adhere. This practice helps to avoid confusion and institutes a policy of fairness, as each student is judged solely based on his own actions. Additionally it encourages the individual to excel because he knows the only way he can receive praise or reap the benefits of success, is by his own merit.
The independent group contingency theory prevents scapegoating. No individual is reliant on the other, forcing him to put in the necessary effort to find his own individual success. Therefore if a fellow group member or classmate were to "fail," the rest of the group is not bitter or affected. This practice promotes an "every man for himself" philosophy that is designed to bring out the best in each individual, while eliminating peer pressure from other group members.
When practicing the independent group contingency theory, the teacher or leader is able to more easily recognize each individual's strengths and weaknesses. When working in a group environment in which every member receives the same grade, reward or punishment, one member has the ability to take control, making it easy for the contributions of others to fade into the background. But by judging each individual based on his behavior or effort, the teacher can access where this individual actually stands.
Despite all of the advantages of the independent group contingency theory, for some individuals the method may not be the correct fit. The system promotes the accountability of each given individual, which in effect eliminates the importance of teamwork. Additionally, it can be discouraging for those who may not be as strong in a given area. The situation can cause a student to be the subject of ridicule after his perceived "weakness" has been exposed. Also the system could backfire. Some individuals may be more motivated by helping the group cause and being the "hero" as opposed to earning the praise only for themselves.
