While most studies in the field of consumer research acknowledge differences between consumption patterns of distinct consumer groups, research dealing with the attitude-behavior gap has hitherto not been sufficiently linked with these findings. As a result, attitutde behavior gap has been often conceptualized as a uniform phenomen for all consumer groups leavin variances across distinct groups largely unexplored. Based on a representative survey (N=1000) among German consumers, this paper challenges this assumption and presents five consumer clusters with different attitude-behavior gaps related to distinct demographic and socio-psychological characteristics
