Opposing evidence from the case study of David Reimer. This is because it found that despite trying to raise David as a girl, he was never happy as a girl and later resumed his masculine identity. This is a limitation because if gender is learned within a social context, he should have been able to be socialised into being a girl. In contrast, David’s case better supports the biological explanation for gender development that proposes his chromosomes and hormones were more important in determining his gender.
