Description
This thought-provoking book critically examines the relationship between law, neuroscience, gender identity, and the concept of biological sex. Challenging the growing reliance on “brain-sex” theories, the book argues that neuroscience cannot provide a clear or reliable biological foundation for defining rigid categories of male and female within legal systems.
Throughout Western history, societies and legal institutions have searched for fixed biological markers to determine what constitutes “true sex.” From anatomy and chromosomes to hormones and genetics, different scientific approaches have been used to support binary understandings of sex and gender. More recently, theories about sex differences in the brain have gained influence in public discourse and legal discussions surrounding gender identity and LGBTI+ rights.
The book argues that these brain-based theories are no more capable than previous biological models of producing fair, coherent, or just legal outcomes. Through an analysis of Australian legal cases involving medical interventions for transgender minors and intersex minors, the author demonstrates how legal systems struggle to consistently define and regulate sexed and gendered identities.
Focusing on contested questions of bodily autonomy, gender identity development, and legal recognition, the text highlights the inconsistencies in how law interprets concepts of male and female identity. It contends that the law’s attempt to create and enforce rigid binary sex categories is increasingly difficult to justify in light of scientific complexity and human diversity.
