Active involvement, familiarity, framing, and the illusion of control during decision support system use

摘要

Results of a laboratory experiment on Decision Support System(DSS) use indicated that (a) active involvement in model building anddata entry, (b) familiarity with model execution and the decisionsituation, and (c) consistency between a amative solution and thealternative encouraged by the problem frame led to an illusion ofcontrol, defined as an unwarranted inflation in expectations ofsuccess. Furthermore, higher expectations of success were associatedwith greater user satisfaction, better mood, and lower preference forthinking more before making the final decision. Higher expectationsof success were less likely to be associated with preference forcreating another model but were more likely to be associated withpreference for further refinements to the existing DSS model beforemaking the final decision. However, variations in expectations ofsuccess induced by sources of illusion of control were not associatedwith variations in decision performance. Implications for practiceand research are presented.
