MAJOR PERSONALITY STUDY FINDS THAT TRAITS ARE MOSTLY INHERITED. THE genetic makeup of a child is a stronger influence on personality than child rearing, according to the first study to examine identical twins reared in different families. The findings shatter a widespread belief among experts and laymen alike in the primacy of family influence and are sure to engender fierce debate.
For identical twins, heritability estimates hovered around 46%, and 23% for fraternal twins (a heritability of 1.00 means that all variance is genetic; Jang et al., 1996). Together, this early work was very clear in its suggestion that there are some genetic influences on personality.n the early years examining the links between genes and personality, it was typical for a study to examine self-reports of personality and compare the self-reports between fraternal twins--who share roughly 50% of their genes--to those of identical twins--who share 100% of their genes.
