Assessing a person’s sense of gender by completing the BSRI reduces the complex concept of ‘gender’ to a series of numbers, therefore not reflecting the reality of gender. Also, the BSRI may be culturally and historically biased, as certain behaviours are seen as ‘masculine’ or ‘feminine’, which may not be true of all cultures at all times.
