There are some of the methods and additions with the help of which the rationalistic approach could be comprehensive. The first and most important point is that to make sure that whether it could be used to cultivate a philosophy of agreement and denial with obligations. The other important point is that if in a situation an individual is able to tell about the features of the situation, the rationalistic theory need to help in predicting the change that could take place. There are certain limitations also in rationalistic approach like it does not consider the prior institutional context. In order to over-come the weaknesses and the limitation there is a need of more historical, academically informed and practical work. This would help in understanding the specific situations due to which cooperation took place in much better way.
Whereas on the other hand in the reflective approach, institutions are mostly not created intentionally by people instead it develops gradually with less or no international process. Also as per this approach institutions are not taken very seriously by the individuals who are really affected by them. As per the reflective approach the assumption of utility maximization does not give information regarding the foundation of institutions[ L. Lisa, “International Organizations.” Handbook of International Relations (2012): 326.]. International institutions appeared from previous established situations, the most important of which cannot be described as if they were agreements among rational folks maximizing some utility meaning. The biggest drawback of the reflective approach is that the students of world politics were not able to get a clear reflective study program. The strengths of reflective approach or we can say the points which reflective approach could add to the rationalistic approach are like it takes into consideration the cultural variations. One of the other points was that the reflective approach disputes for a basic and deep rooted dynamic in a theory of institutions whereas we have seen that the rationalistic approach do not consider the prior institutional contexts.
