 Social constructivists deny that there are any essential differences between male and female bodies or psychologies that explain women's position in the family (Haslanger 2000). Social constructivists have explored the ways in which culture and society have shaped even the most ostensibly natural differences between men and women. They argue that many of the differences between men and women alleged to be the source of gender inequality should instead be viewed as the outcome of that inequality.  For example, they claim that we cannot understand sex-based differentials of height and physical strength without considering the influence of diet, division of labor, and physical training. Feminist historians and anthropologists have sought to demonstrate the significant roles that culture, religion and social class have played in shaping women's lives (Scott 1988).
