I am thinking about a question of Behavioral Operations Management (BOM): how to define a contribution to the literature? For the traditional operational research, it can be a new model, a new algorithm or a model for a new problem. But what is a contribution in BOM? In BOM, we first observe the system biased performance (primary), then look into the biased decisions which lead to the performance (secondary), try to find out what biases induce such decisions and how (tertiary), and is it necessary to go deeper to explore reasons for the biases (fourth)? I found it is hard to seek for explanations in the fourth level. However, without the fourth level, how can we propose suggestions to adjust these biased behaviors in the decision process? Without efficient suggestions, what is the contribution of a research? Or, am I wrong with the definition of contribution in BOM? How far should we go in this field?
