The Influence of Birth Order on Personality Traits

Research on birth order suggests that it may not have a significant impact on personality traits as previously believed. Many traditional stereotypes indicate that firstborns are more responsible and driven, while later-born siblings are perceived as more creative and easygoing. However, studies indicate that when analyzing personality traits—specifically within the framework of the Big Five—there is little correlation between birth order position and personality differences. The only notable finding suggests that firstborns may score slightly higher on measures of intelligence, though this does not universally determine individual outcomes, as many later-born siblings can also exhibit high intelligence.
