The personality traits tied to birth order have long been the subject of debate, with first-borns often considered responsible and controlling, youngest children seen as spoiled, and middle children labeled as neglected. However, a recent study challenges these stereotypes, suggesting that middle children may actually excel in qualities like honesty, humility, agreeableness, and emotional intelligence.
This idea of birth order influencing personality was first proposed over a century ago by Austrian psychologist Alfred Adler, and it has sparked both intrigue and skepticism in the scientific community ever since. While theories about birth order’s impact on personality have evolved, experts have yet to reach a definitive consensus.
The notion of “Middle-child syndrome,” often associated with feelings of neglect, is commonly cited in discussions about birth order. However, Canadian researchers Michael Ashton and Kibeom Lee have found that middle children may benefit from this perceived neglect, as they tend to score higher in traits such as honesty, humility, and emotional regulation. Using the HEXACO Personality Inventory, which measures factors like agreeableness and emotionality, the study showed that middle children were more likely to forgive, cooperate, and manage their temper.
Interestingly, the study also found that first-borns scored the lowest in honesty and agreeability, while youngest children were still more likely to exhibit positive traits than their elder siblings. Despite these findings, earlier research has cast doubt on the influence of birth order, with some studies suggesting no clear correlation between birth order and personality. Historical figures like Martin Luther King Jr. and Abraham Lincoln, who defy the typical middle-child narrative, highlight the complexity of the issue.
