This document discusses different approaches to studying consumer behavior. It begins by explaining the managerial approach, which views consumer behavior as an applied social science to develop marketing strategies. It focuses on individual consumers, their attitudes, perceptions, demographics, and thought processes. There are risks to this approach if it overemphasizes rationality or focuses too much on purchases over consumption. The document then discusses the holistic approach, which views consumer behavior as a legitimate social science focus without direct application to marketing. This approach is more macro-level, focusing on how environmental and cultural factors influence consumption behaviors on a societal level. It emphasizes the symbolic and social aspects of consumption experiences over just purchases.
