“…We also wondered about the extent to which self-enhancement is heritable. Although the possibility of genetic effects on the BTAE per se has largely gone unexplored, numerous studies have demonstrated substantial genetic contribution to variation in self-regard, including self-esteem, narcissism, and name-liking (Luo, Cai, Sedikides, & Song, 2014; Luo, Shi, Cai, Wu, & Song, 2014; Neiss, Sedikides, & Stevenson, 2002, 2006; Vernon, Villani, Vickers, & Harris, 2008). These findings suggest that the related construct of BTAE may also be genetically influenced.…”
