These more recent findings regarding the impact of negative affect on creativity are consistent withthe“sadder-but-wiser versus happier-and-smarter”hypothesis put forward by Staw & Barsade (1993,p.304).Using managerial simulations, Staw & Barsade compared two psychological theories concerning affect and performance to test whether people positive in disposition perform better or worse on decisional and interpersonal tasks. Results of these tests support the happier-but-smarter (happier people are productive, but do not necessarily make the best decisions) hypothesis rather than the sadder-but-wiser (managerial decision making is improved by negative affect) hypothesis. Staw & Barsade found in particular that happy people may be the most productive (“the happier-but-smarter” hypothesis), although it is possible that this relationship may be based on more personal disposition.
