A further limitation is that the theory supports the nurture side of the nature vs nurture debate and is an environmentally determinist and reductionist theory. The theory suggests that gender dysphoria is determined solely by social factors such as the lack of a role model of the same gender. This is a limitation because this is an over-simplistic explanation which ignores any evidence for the nature explanation e.g. research suggesting that gender dysphoria has a genetic basis or is linked to brain development similar to that of the opposite gender.
