 Birth order appears not to influence any of the “big five” personality traits

TIME (10/20, Basu) reports that a study published Oct. 19 in PNAS has found little evidence to back up “oft-repeated stereotypes about birth order and personality.” Researchers arrived at that conclusion after having reviewed “data sets that include 5,240 Americans, 4,489 British people, and 10,457 Germans because they wanted to compare people not only within their families but also with other sibling sets.”

HealthDay (10/20, Thompson) reports that the study concluded that “birth order does not influence any of the ‘big five’ personality traits – extroversion, emotional stability, agreeableness, conscientiousness or openness to experience.”
