Hollander thought it would be beneficial to form a smaller group of social scientists, focused primarily on experimental research. Since the psychological societies of the time were so vast, this would allow a smaller organization that could have more intimate dialogue on the subject matter, and also give the organization more flexibility.[1] Hollander and Vinacke wrote 35 other prominent social psychologists of the time. Those that shown interest in the endeavor were invited to a meeting to discuss the structure of forming the SESP.[1] The meeting took place in Chicago on May 1, 1965.
