Replication data for: Replication and Extension of Fulmer et al.'s (2010) Finding that Individual and Culture-Level Extroversion Interact to Enhance Subjective Well-Being

This paper is an examination of the positive interactive effect of individual and culture-level extroversion on subjective well-being originally reported in Fulmer et al. (2010). The present study used 10,018 participants from the International College Survey 2001 (ICS 2001). Study 1 successfully replicated the original effect. However, this effect disappeared in Study 2, when additional controls were fit. Instead, Study 2 suggested that only the main effects of individual extroversion and country happiness, as well as age and gender, predicted individual subjective well-being. Results may have been due to a lack of power, or the absence of any real interactive effect. More research is needed to resolve this.
