OBM might be seen as one of the distant branches of scientific management, originally inspired by Taylor.[12] The principal difference between scientific management and OBM might be on the conceptual underpinnings: OBM is based on B.F. Skinner's science of human behavior.[13] Because different people behave differently in the same situation, studies from multiple disciplines using multiple research methods create confusion, hindering a unified concept of organizational behavior.[14] For example, the Hawthorne Studies, where sociologists attempted to improve worker productivity by changing the lighting in the work space, they found that the productivity of the workers had improved just by being observed, not because of the improved lighting but because somebody was taking an interest in them.[15] Yet, this study can also point to the social stage in Maslow's Hierarchy of needs, specifically the social need to belong[16]
