Summary:
A very thorough study conducted jointly by researchers at Ohio State University, University of Oklahoma, and the University of North Carolina-Chapel Hill, found no correlation between intelligence and birth order once other factors had been taken into consideration.

Details or Sample:
Has your older brother or sister ever told you that birth order affects intelligence? That the first-born is usually smarter than later-born children? The best evidence says they´re wrong. A very thorough study conducted jointly by researchers at Ohio State University, University of Oklahoma, and the University of North Carolina-Chapel Hill, found no correlation between intelligence and birth order once other factors had been taken into consideration.

These researchers, Aaron Wichman, Joseph Lee Rodgers, and Robert MacCallum, used data provided from a nationwide sample of nearly 3000 families. On first review, there did seem to be a correlation between lower birth order and intelligence. Most previous studies saw this same correlation, and the myth was born that later birth order meant a likelihood of lower intelligence relative to older brothers and sisters

(middle section omitted from summary details)

In short, children within the same family tend to have similar scores on intelligence tests. According to Wichman, "There is no evidence of any significant association between birth order and intelligence. It´s not your birth order that is important - family environment and genetic influences are the really important factors." So when your older sibling starts to throw the old birth order myth in your face, tell them they aren´t so smart after all.
