Birth Order and Personality
The belief that birth order has a lasting impact on personality is widespread and frequently referred to in popular psychology literature. Alfred Adler (1870 - 1937), an Austrian psychotherapist, was one of the first to argue that birth order contributes to the formation of character. He maintained that firstborn children could often be profoundly affected by the loss of status brought about by the birth of siblings. Eldest children, according to Adler, were prone to be both anxious and conscientious, that is, inclined to work hard, perhaps in order to regain a position of primacy within the family.
Since Adler, there have been numerous attempts to verify the influence of birth order on a range of personality traits, in particular: rebelliousness, conscientiousness, extroversion, agreeableness, and anxiety. Some studies have found that last born children tend to be more extrovert and agreeable, that is, they not only seek out the company of others but also tend to get along well with other people. Middle children, on the other hand, are least likely to be compliant. They tend to rebel, perhaps in an attempt to define themselves as 'special' in relation to their more conscientious elder siblings and agreeable younger siblings.
