Are our personalities the result of our genetic inheritance or the result of our enviroment?


Recent studies show that personality develoment is influenced more by genetic than by enviroment. These studies are based on twins who had been separated at birth and reared in different families. Even thought the enviroment were totally different, the twins personalities reminded strikingly similar. Take for example the Jim twins.

These brothers where separated five weeks after birth and reunited 39 years later. Both brother were named Jim by their adopted parents.
They both married women named Linda, divorced, and remarried women named Betty. Each had a son named James Allen, and dog named toy.
When the twins were reunited, it was discovered that they had identical hobbies, interests and work history. Even though their enviroments has been entirely different, the personalities were remarkably similar.

The Jim twins and similar studies of twins, leave a strong suggestion that there are genetic factors at work which overpower enviromental influences.
