The study of whether and how traits for behavior are inherited is called behavioral genetics . Scientists have long tried to figure out whether behavior is shaped by our genes or by how we are raised. For a long time, scientists took one position or the other. They believed that either nature or nurture was responsible, but not both. What no one knows is just how nature and nurture work together.
Some researchers believe that genes shape our inborn frame of mind, or temperament .
According to this theory, we may inherit our tendency to be shy or bold, risk-taking or cautious. For example, a shy boy who is encouraged to try out new situations may learn to be more outgoing. Another shy child who is pushed too quickly into strange situations may always remain timid. So might a shy child who is allowed to hide behind his parents. There is some evidence that to some degree, abilities also may be inherited.
