A few years after the first edition of the Nurture Assumption was published, I realized that the theory proposed in that book, Group Socialization theory, was incomplete.

在《教育设想》第一版发表几年后，我意识到书中所写到的一个理论——团体社会化理论还不完善。

Group Socialization Theory doesn't explain, for example, why identical twins have different personalities, even if they're reared in the same home and belong to the same peer group.

例如，团体社会化理论并不能解释为什么同卵双胞胎会有不同的个性，即使他们是在同一个家庭中长大并属于同一个同龄群体。
