Studying identical twins allows psychologists to control for genetic similarities (since identical twins share nearly all their DNA) and focus on the effects of different environments or experiences. This helps in understanding how similar environments shared by relatives (like identical twins raised together vs. apart) can influence various traits and behaviors, teasing out the environmental influences from the genetic ones.
