Grit has been proposed as an important factor influencing success in various domains. It might therefore be used for predicting success and as a target of interventions aiming to improve achievement. The present two studies examined domain-specificity of grit and the association between grit and result in a scholastic aptitude test in large samples of university applicants (total N = 4,920). Grit showed a small-to-moderate negative association with the test results. This negative association did not differ strongly between general grit and grit measured in relation to studying or hobbies. The study shows that high grit does not predict success in the standardized university admission test. Furthermore, focusing grit on the domain of interest does not improve its predictive ability. Keywords grit, scholastic aptitude, conscientiousness, education, intelligence, motivation Grit, defined as "perseverance and passion for long-term goals" (Duckworth, Peterson, Matthews, & Kelly, 2007, p. 1087, has been proposed as an important factor which might explain differences in success of otherwise similarly able individuals. For example, studies found that grit is positively associated with undergraduates' grade point average (Bowman, Hill, Denson, & Bronkema, 2015;Duckworth et al., 2007), rankings in the spelling bee (Duckworth, Kirby, Tsukayama, Berstein, & Ericsson, 2011;Duckworth et al., 2007), and teachers' effectiveness (Robertson-Kraft & Duckworth, 2014). A recent meta-analysis (Credé, Tynan, & Harms, 2017) found positive associations of grit with achievement in both academic and nonacademic domains. Yet, usefulness of the grit construct may be limited given that it is strongly correlated with a closely related conscientiousness personality trait and it does not seem to add much information for predicting academic achievement once conscientiousness is taken into account (Credé et al., 2017). Moreover, grit is traditionally thought to consist of perseverance of effort and consistency of interest facets (Duckworth et al., 2007); however, based on the metaanalysis, Credé et al. (2017) argue that combining the two facets in a single higher-order 2 construct is not warranted and that it may result in loss of predictive ability. Perseverance of effort was shown to predict achievement better than consistency of interest and it also showed incremental validity above conscientiousness when predicting academic achievement.Grit is supposed to lead to success mostly by helping an individual to focus on a stable longterm goal . Consistently, it has been found that grit predicts retention in various domains, such as marriage, workplace, education, and military training (EskreisWinkler, Shulman, Beal, & Duckworth, 2014;Kelly, Matthews, & Bartone, 2014). Other research suggests that the effect of grit on success might be mediated by deliberate practice. Gritty people may be more likely to exert effort and engage in relatively less enjoyable activities in order to achieve their goals (Duckworth et al., 2011).Since grit is usual...
