The effect of birth order on a child’s development have long been the subject of research, with psychologists and biologists alike taking sides as to whether position in a family has real implications later in life. Studies have examined the consequences that birth order can have on everything from personality and intelligence, to job earning potential. In the recent years, researchers have taken cues from studies dating as far back as the 1960’s and re-examining how birth order plays a role in the development of human personality, educational achievement, and behaviors.
