Reconsidering the 'Extreme Male Brain' Theory

Pioneer of extreme male brain theory - Simon Baron-Cohen, the originator of the 'extreme male brain' concept in autism research, has expressed regret over the terminology he once championed, citing its potential for misinterpretation. His theory, which proposed that autistic individuals exhibit a heightened focus on systemising rather than empathising, has significantly shaped public understanding of autism over the past two decades. However, Baron-Cohen now believes the label, though scientifically grounded, may have oversimplified the complexity of the condition and contributed to misconceptions.

“Some of those terms were very easily misunderstood and so I do regret that,” he said. “It can lead to simplistic headlines like 'autistic people lack empathy', which is not true.”

Baron-Cohen emphasized that while the scientific foundation of his work remains robust, the phrase has been a source of controversy. He noted that the term 'male brain' and its contrast with 'female brain' have sometimes reinforced stereotypes, particularly in how autism is perceived as a condition predominantly linked to males. This has led to the misconception that autistic individuals, especially women, are less capable of understanding others' emotions.

New Research Center and Funding

Speaking to the Guardian before the announcement of a £26m ($34.5m) gift to Cambridge University from the US philanthropist Lisa Yang, Baron-Cohen highlighted the significance of the funding. The donation will support the creation of the K Lisa Yang Centre for Autism Research, alongside a clinical autism center within a future Cambridge children’s hospital. These initiatives are expected to be led by Baron-Cohen, who aims to shift the focus of autism research toward areas previously underexplored, particularly physical health.

“The dialogue with the autism community is changing where we shine a light and which are the phenomena, or the problems, that need attention and that were being neglected,” he said.

Baron-Cohen stressed that the new center will address critical gaps in autism research, such as the impact of physical health conditions on autistic individuals. He pointed out that while the mind and brain are often the primary focus, the physical well-being of autistic people has been overlooked. For instance, recent findings by his team suggest that autistic individuals are at a significantly higher risk of cardiovascular disease, a discovery that could have far-reaching implications for healthcare.

Cardiovascular Risks and Health Disparities

Baron-Cohen’s latest research, based on data from 141,672 people, revealed that autistic women face a 71% greater risk of heart attacks, strokes, and other cardiac events, even after accounting for known risk factors like blood pressure, diabetes, and obesity. This finding, though not yet peer-reviewed, has sparked discussions about the need to incorporate physical health into autism studies. He explained that the connection between autism and cardiovascular issues might stem from various factors, including challenges in accessing NHS services or genetic predispositions.

“If you’d asked me 20 years ago to look at autism and cardiovascular disease, it just wouldn’t have been on our radar, but it’s come from the autism community,” Baron-Cohen said.

The center will also explore the unique health experiences of autistic women, such as distress related to childbirth and menstrual irregularities, which some earlier studies suggest are more prevalent. These issues could be tied to sensory hypersensitivity or hormonal influences, according to Baron-Cohen. He emphasized that the autism community’s input is crucial in identifying these priorities, ensuring research reflects the real-world challenges faced by individuals.

Evolution of Research Priorities

Baron-Cohen acknowledged that his earlier work, including the 'extreme male brain' theory, has faced criticism for framing autism as an empathy deficit. He clarified that his research actually showed that autistic people often differ in cognitive empathy—interpreting facial expressions and language—but not in affective empathy, which involves the internal response to others’ emotions. “Once they know that someone is upset, it upsets them and they want to do something about it,” he explained, challenging the notion that autistic individuals are inherently emotionally detached.

“There’s a kind of myth that autistic people lack empathy,” said Baron-Cohen.

His approach has evolved over time, influenced by ongoing feedback from the autism community. This is evident in the recent decision to drop a genome sequencing project after a two-year consultation process. Baron-Cohen noted that the emphasis on involving autistic individuals in shaping research priorities has grown substantially. “I can’t generalise, but many autistic people think differently, they’re not just being led by fashion or convention, they’re thinking from first principles for themselves,” he added.

Broader Implications and Future Directions

The Cambridge donation comes amid a continued rise in autism diagnoses. In the UK, the number of diagnosed cases saw a nearly 800% increase between 1998 and 2018, with 2024-2025 marking another significant surge. Baron-Cohen believes this trend underscores the need for more comprehensive research, particularly in areas like cardiovascular health and quality of life improvements. He highlighted that the new center will prioritise initiatives such as earlier diagnosis, practical interventions, and efforts to enhance life expectancy.

“The research centre is expected to focus on improving life expectancy and health outcomes for autistic people, earlier diagnosis and practical solutions to improve quality of life,” he said.

Baron-Cohen also stressed the importance of addressing disparities in healthcare access. He suggested that autistic individuals may face unique challenges in navigating medical systems, which can exacerbate existing health risks. By integrating the perspectives of the autism community, he aims to create a more inclusive and accurate understanding of the condition, moving beyond outdated stereotypes to explore a wider range of experiences and needs.

Conclusion and Ongoing Impact

While Baron-Cohen has distanced himself from the 'extreme male brain' label, he remains committed to advancing autism research. His work continues to influence both academic and public discourse, even as the field evolves to embrace a more nuanced view of the condition. The new funding and research initiatives represent a significant step toward addressing the multifaceted aspects of autism, ensuring that the voices of those affected are central to the scientific inquiry. As the K Lisa Yang Centre for Autism Research takes shape, Baron-Cohen’s efforts to align research with community priorities may redefine the trajectory of autism studies in the years to come.
