This paper extends the effort–accuracy framework of cognition by taking into account the perceived strategy restrictiveness of decision aids, and tests the extended framework in a context in which online decision aids are used to elicit consumers’ preferences, automate the processing of the preferences, and provide product advice for consumers. Three types of decision aids with different decision strategy support capabilities (an additive-compensatory based aid, an elimination-based aid, and a hybrid aid supporting both strategies) are compared in terms of users’ perceptions of strategy restrictiveness, advice quality, and cognitive effort. These comparisons are grounded on the properties of normativeness and complementarity of decision strategies employed by the aids. A normative strategy takes into account both the users’ attribute preferences and the relative importance of such preferences, and allows for trade-offs among preferences (e.g., additive–compensatory). Strategy complementarity indicates support for decision rules based on multiple strategies (e.g., both additive–compensatory and elimination strategies). The experimental results support the validity of the extended e…
