In addition to sharing 100 percent of genes in common, identical twins also tend to share environments in common, such as living in the same household, going to the same schools, or socializing with the same neighbors. To what extent does the shared environment contribute to variations in twin personalities?

▸ The shared environment contributes very little to variations in twin personalities.

▸ Shared environmental influences account for approximately 62 percent of the variability in twin personalities.

▸ Current research reveals that the shared environment takes on even greater importance than previously believed.

▸ Just as with non-twins, genetics contributes 50 percent to shaping personality, and environment contributes 50 percent to shaping personality.
