Theory From A Psychologist

A Psychologist psychologist from the USA put forward a theory about 20 years ago Theory set up. It says that
the big sister is perfectionistic and clever, the brother in the middle likes to take care of others and the little sister takes things out of her own hands that her big siblings would never have dared to do.

New Data Of Studies Evaluated

Now researchers from the German cities of Leipzig and Mainz have evaluated data that come from three large studies done in the United States, Germany, and Great Britain. In total, more than 20,000 people have been examined for these studies. The result clearly says that the theory of the psychologist from the USA is not true. The only thing the researchers have found is that firstborns are in most cases slightly more intelligent, but really only touch and not worth mentioning. And even this is not always the case, because there were also examples where the younger siblings are smarter.
