Though the research bureau was a major contribution, it was not without flaws. Lazarsfeld emphasized that a research institution is capable of existing in an organized fashion but that the commandeering and leadership really dictated the success of it. Lazarsfeld was successful for nearly two decades; however actors within this particular system could manipulate the machinations of the institution and thus derail the program. Another negative repercussion of having the type of leadership that Lazarsfeld provided was that the organization and its methodology was determined by his preferencesnot allowing in this case for statistics to be utilized and that the data sets were unable to be replicated and generalized.
