About the Course:

Wright, who wrote on twins for the New Yorker, presents an examination of twin studies and what we have learned from them. Much of what we know about genetics comes from studying identical and fraternal twins who were reared apart. Wright shows how, historically, different interpretations of these studies have ended up creating trends in psychology or fueling social policy, and that researchers are still tracing the heritability of such things as IQ, addictive behavior, and criminal behavior through siblings, fraternal twins, and identical twins in attempts to resolve the nature versus nurture debate. 

This course is based on the , Twins: And What They Tell Us About Who We Are created by Wright, Lawrence
