Introduction
The contemporary gender debate has ceased to be a discussion about biology, becoming instead a battlefield for power and social structure. In her book Testosterone Rex, Cordelia Fine exposes the mechanism of "biological determinism," in which hormones and reproductive organs serve as tools to legitimize inequality. The reader will learn why there is no simple causal bridge between anatomy and psychology, and how culture and institutions shape our "natural" destiny.
The Gender Dispute and the Inflation of Biology
The debate over gender is no longer about the existence of human bodies, but whether it is permissible to derive a metaphysics of two distinct natures from reproductive dimorphism. The modern dispute is a clash of ideologies in which science is instrumentalized. The inflation of biology serves as a technology of power: first, a hierarchy is created, and then it is declared "natural." As a result, arbitrary social divisions gain the appearance of an indisputable order, allowing decision-makers to avoid responsibility for real-world inequalities.
Brain Plasticity and the Myth of the Lehman Sisters
Daphna Joel's research proves that the human brain is not divided into two types, but rather forms mosaics of traits. Anatomical differences are marginal and often disappear when variables such as brain volume are controlled. Meanwhile, the myth of the "Lehman Sisters"—the belief that women would have naturally prevented the financial crisis—is harmful because it perpetuates paternalism. Instead of emancipation, it relegates women to the role of "fixers" of male mistakes, confirming that gender in economics is often just a costume for systemic pathologies.
Children as Detectives and Evolutionary Myths
Children, as gender detectives, actively interpret social patterns, adapting to them from an early age. This is a process of self-socialization that wastes human potential through the early segregation of aspirations. At the same time, the theory of sexual selection requires revision—modern biology rejects the model of the "passive female" and "aggressive male" in favor of complex, environment-dependent strategies. By rewarding specific behaviors, institutions themselves produce the differences they later "discover" to be biological.
Algorithms, Parliament, and the Limits of Law
The automation of stereotypes in the AI era carries the risk of embedding biases into digital code. The debate in the European Parliament resembles an opera buffa, where every faction—from conservatives to the left—uses gender as a political tool. The law should not interfere with "nature," but with the architecture of incentives. The economic costs of gender segregation are enormous, as assigning competencies based on gender destroys system efficiency. Scientific facts about the plasticity of the organism must replace ideological overinterpretations.
Summary
In a world of algorithms, are we not risking the return of prejudice in a new guise? If biology becomes merely code for predictive systems, our belief in its immutability will prove to be the most effective tool of domination. The real challenge is not to discover the "nature" of gender, but to understand why we so desperately need the myth to escape the burden of our own freedom. Our social future is not a verdict of nature, but a task for reason and institutions.
