If marketers had found no classificatory approaches readymade in the behavioral sciences, how would they have construed “the consumer” for purposes of classification? In this paper, I argue that we should select our approaches to classification in the light of the task at hand. Classification systems for persons — as opposed to behaviors — have hitherto been stressed even though, in our central assignment as marketers, we address behaviors rather than persons. A classification system for behaviors is proposed and its implications are discussed.
