•Aim/Research Question
Are You a Natural?
To determine with a reasonable degree of confidence which psychological characteristics appear to be determined primarily by genetic factors and which are molded more by environment.

•Results
Are You a Natural?
Correlations for characteristics measured were remarkably similar. They were close to 1.00 and no lower than .700 for MZA and MZT identical twin pairs.
•Conclusion
Are You a Natural?
Findings indicate that genetic factors appear to account for most of the variations in a variety of human characteristics. Genetically identical humans reared apart grew into adults who were extraordinarily similar in basic psychology and personality.
