In 2014, France was the scene of a scientific controversy involving two renowned researchers: Catherine Vidal and Franck Ramus. At the heart of the debate: the differences between male and female brains. A decade later, what remains?<\/p>\n\n\n\n\n\n\n\n
In 2011, neurobiologist Catherine Vidal hit the nail on the head at a TED conference entitled \u00abDoes the brain have a sex?\u00bb. She defended a radical thesis: men and women express no significant cognitive differences throughout their lives. Vidal immediately denounces the sexist excesses of 19th-century science.th<\/sup> century (notably by Paul Broca), then deconstructs, one by one, four tenacious prejudices:<\/p>\n\n\n\n Vidal methodically refutes these four assertions, asserting that identity and behavioral differences between the sexes are constructed through socialization, i.e. the internalization of gender stereotypes inculcated from childhood. The brain's plasticity is extraordinarily flexible. She is thus fully in line with the socioconstructivist paradigm.<\/p>\n\n\n\n Three years later, neuroscientist Franck Ramus took part in a TED conference on the same theme, responding to Vidal's theses. While he shares Vidal's criticism of 19th-century sexist prejudicesth<\/sup>, He takes a more nuanced stance, relying on experimental data that Vidal overlooks:<\/p>\n\n\n\n In addition to the research he and his team have carried out, Ramus draws on a solid body of international literature confirming the existence of micro-differences between the sexes.<\/p>\n\n\n\n Ramus invites Vidal to a public debate, but to no avail. Each remained locked in his own monologue. Vidal continued to spread his constructivist theses at conferences, while Ramus published an ironic article with Nicolas Gauvrit entitled \u00abLa m\u00e9thode Vidal\u00bb, denouncing his refusal to consider contradictory studies.<\/p>\n\n\n\n In 2016, Franck Ramus co-signed an article with eight other researchers in Le Monde entitled \u00abEn sciences, les diff\u00e9rences hommes-femmes m\u00e9ritent mieux que des caricatures\u00bb (\u00abIn science, gender differences deserve better than caricatures\u00bb). This intervention denounces the rejection of the international scientific literature on the subject of cognitive micro-differences between the sexes, targeting in particular Catherine Vidal and the proponents of the \"myth of indifferentiation\".<\/p>\n\n\n\n In the media and among university humanities faculties, Vidal has clearly won the day. In neuroscience laboratories and journals, on the other hand, the scientific community is leaning towards Ramus' position.<\/p>\n\n\n\n In France, the debate on gender differences unfortunately boils down to a simplistic face-off: innate versus acquired. On the one hand, the human sciences and progressive sensibilities are massively aligned with the Vidalian position. Cognitive differences between the sexes are said to be purely acquired<\/em>. On the other hand, the hard sciences and more conservative sensibilities tend to identify with the Ramusian camp. These differences are partly due to innate<\/em>.<\/p>\n\n\n\n This scientific divide, correlated with an ideological divide, locks everyone into their own camp. Yet this opposition masks an essential aspect. In reality, there are not two, but three distinct paradigms:<\/p>\n\n\n\n Viewed from this tripartite angle, the positions of Ramus and Vidal appear in a new light: moderate for Ramus and relatively radical for Vidal.<\/p>\n\n\n\n In his impassioned defense of brain plasticity, Vidal makes two major errors that weaken the scientific significance of his theses.<\/p>\n\n\n\n On the one hand, it presents its positions as definitive and consensual,<\/strong> without taking into account the research and debates taking place in the scientific community. Prisoners of a strong confirmation bias, she selects the rare studies that support her convictions, while neglecting the bulk of scientific research, particularly Anglo-Saxon.<\/p>\n\n\n\n On the other hand, it tends to blur the boundary between facts and value judgments, confusing inequality with injustice and sliding insensitively from a descriptive analysis to a normative stance. For fear of being accused of sexism or conservatism, it adopts a principled egalitarianism, without respecting the essential distinctions between science, morality and politics.<\/p>\n\n\n\n\n
