Now this may be more than a stereotype after a new study conducted by researchers from MIT, University of Florida, and Northwestern University.
The researchers followed thousands of sets of brothers in Denmark and Florida. They wanted a large sample size from two drastically different cultures. In both locations, it was discovered that the second-born brother was more likely to have discipline issues in school.
