Does a “Triple Package” of traits predict success?

What individual factors predict success? We tested Chua and Rubenfeld's (2014) widely publicized “Triple Package” hypothesis that a tendency toward impulse control, personal insecurity, and a belief in the superiority of one's cultural or ethnic group combine to increase the odds that individuals will attain exceptional achievement. Consistent with previous research, we found in two sizable samples (combined N = 1258) that parents' level of education and individuals' own cognitive ability robustly predicted a composite measure of success that included income, education, and awards. Other factors such as impulse control and emotional stability also appeared to be salutary. But despite measuring personal insecurity in four different ways and measuring success in three different ways, we did not find support for any plausible version of Chua and Rubenfeld's proposed synergistic trinity of success-engendering personality traits.
