quitting scored higher than those who did not plan on quitting. Future research There are several areas in which the literature on learned industriousness can be expanded. Due to the unclear results of Eisenberger's study of a Learned Industriousness-Learned Helplessness Continuum, further research should be done to provide evidence for or against its existence. This research could be useful for personnel selection purposes and understanding performance in the workplace. Also, the most current smoking-related learned industriousness research has been correlational; experimental studies could not only be powerful evidence for the theory but also generate important practical contributions for smoking cessation therapy.
