Because different disciplines often use different assumptions in the research, researchers
do not always provide answers, or, they may provide contradictory answers (Bellman et
al. 2006; Zhou et al. 2007). The research methods used in online consumer behavior are
primarily borrowed from various disciplines including cognitive psychology, social
psychology, marketing science, management science, and information systems. Thirdly,
online consumer behavior involves many antecedent factors and thus becomes a very
complicated social-technical phenomenon. Therefore, fully understanding it becomes
very difficult.
