Information system (IS) usage has been extensively researched for decades. These theories are built upon the assumption that human decisions are based only on rationality. However, this notion was challenged in more recent years, as Kahneman (2003) demonstrates that human decisions are not only based on rationality but also on intuition. Kahneman’s dual-process theory suggests that cognitive processes underlying social judgments and behavior can be divided into two different systems (system one and system two) depending on whether they operate reflectively or intuitively. Yet, prior IS usage literature examines the construct of habit, which under the evaluation of the dual-process theory is formed in the intuitive system. However, within the research stream of habit, the dual-process theory has not been rigorously considered. Hence, most of the results and implications of habit research are driven by the theoretical assumption of the reflective theories concentrating only on the reflective system and neglect that habit is an unconscious construct formed in the intuitive system. To shed light on IS habit and to improve IS literature rigor on habit, the present research idea aims to analyze IS habit literature to identify whether it has been treated and measured as intuitive or reflective construct.
