The discussion takes its point of departure in a critique of the division of sciences from a queer-feminist theoretical point of view that seeks a societal development in which different bodies and expressions are perceived more equal than what dominant norms are currently allowing, both juridically and socially. By using examples from neuroscientific research on neuronal and behavioral differences between men and women I want to show, how cultural strereotypes and normative assumptions lead so-called objective research to conclusions that form our reality normatively, but do not reflect reality in all its actual diversity -and certainly do not pave the way for non-conform ways of life. The question of how feminist theory can be turned into praxis on this matter is at the core of the discussion.
