Autism research has changed significantly over the past two decades. One of the most influential ideas in the field, the "extreme male brain" theory, helped shape scientific discussions and public understanding for years. Today, however, its creator, Professor Simon Baron-Cohen, believes the phrase itself is no longer helpful because it has often been misunderstood.
In a recent interview, Baron-Cohen acknowledged that the terminology has contributed to misconceptions about autism, particularly the inaccurate belief that autistic people lack empathy. At the same time, he emphasized that while the label may have become outdated, many aspects of the underlying research remain scientifically relevant.
This shift reflects a broader transformation in autism research, where scientists are increasingly working alongside autistic individuals to address practical health concerns, improve diagnosis, and enhance quality of life.
Professor Simon Baron-Cohen introduced the "extreme male brain" theory more than two decades ago. The theory suggested that autism is characterized by a stronger tendency toward systemizing, which is the drive to analyze patterns and systems, compared to empathizing, which involves understanding another person's thoughts and emotions.
Over time, the phrase became widely known outside academic circles. Unfortunately, Baron-Cohen says many people misunderstood what the theory actually meant.
He now believes the terminology has created misleading headlines suggesting autistic people have little or no empathy. According to him, that interpretation does not accurately represent the science.
Instead, he argues that labels such as "male brain" and "female brain" are no longer useful because they can reinforce stereotypes rather than improve understanding.
One of the biggest misunderstandings surrounding autism is the assumption that autistic people do not care about others.
Baron-Cohen explained that his research distinguishes between two different forms of empathy:
Research suggests that some autistic individuals may experience challenges with cognitive empathy. However, many continue to experience affective empathy very strongly.
In simple terms, an autistic person may not immediately recognize that someone is upset, but once they understand the situation, they often care deeply and want to help.
This distinction is important because it challenges one of the most persistent myths surrounding autism.
Professor Baron-Cohen also announced a major milestone for autism research.
A donation worth £26 million (approximately $34.5 million) will establish the K Lisa Yang Centre for Autism Research at the University of Cambridge, along with a future clinical autism center within the planned Cambridge Children's Hospital.
The funding represents one of the largest private investments in autism research ever made at a UK university.
Rather than focusing only on understanding autism itself, researchers plan to prioritize issues that autistic people identify as most important.
Key research areas are expected to include:
The research agenda reflects growing collaboration between scientists and the autistic community.
Historically, autism research has concentrated on neurological and behavioral characteristics.
Baron-Cohen believes physical health has received far less attention than it deserves.
He highlighted evidence suggesting that autistic individuals generally experience shorter life expectancy than the wider population. Understanding why this occurs has become an important research priority.
His team recently analyzed health data from more than 141,000 people. Preliminary findings, which have not yet undergone peer review, indicate that autistic women may face a significantly higher risk of cardiovascular disease.
According to the research:
Researchers caution that these findings are still awaiting independent scientific review. However, if confirmed, they could influence future healthcare recommendations for autistic patients.
Scientists are still investigating why cardiovascular disease appears more common among autistic people.
Several possible explanations include:
Understanding these factors could help doctors provide more targeted preventive care.
Rather than viewing autism solely through a neurological lens, researchers increasingly recognize that comprehensive healthcare must include physical as well as mental wellbeing.
Another growing research priority involves the health experiences of autistic women.
Emerging evidence suggests autistic women may experience higher rates of:
Researchers hope future studies will clarify whether these experiences are linked to sensory sensitivities, hormonal factors, or a combination of both.
This represents an important shift because women's health has often been underrepresented in autism research.
Modern autism research increasingly emphasizes collaboration with autistic individuals.
Baron-Cohen acknowledged that previous research initiatives did not always involve sufficient consultation.
One example involved a proposal to sequence the genomes of 10,000 autistic people. After nearly two years of consultation and criticism from members of the autistic community, the project was ultimately discontinued.
The experience reinforced the importance of involving autistic people early in the research process rather than after major decisions have already been made.
Today, researchers are placing greater value on community feedback to shape future scientific priorities.
Autism diagnoses have increased dramatically over the past several decades.
In the United Kingdom, diagnoses reportedly increased by nearly 800 percent between 1998 and 2018.
More recently, referrals of children to mental health services for possible autism increased by almost 50 percent during the 2024-2025 period.
Some observers have suggested that autism is being overdiagnosed.
Baron-Cohen disagrees with that interpretation.
He argues that pursuing an autism diagnosis is rarely a casual decision. Instead, individuals and families often seek assessments after years of challenges affecting education, employment, relationships, or daily life.
Long waiting lists remain one of the biggest challenges facing autism services.
To address this issue, Baron-Cohen's team is conducting a pilot study exploring whether general practitioners can diagnose autism as accurately as specialist assessment centers.
If successful, this approach could significantly reduce waiting times and improve access to diagnostic services.
Earlier diagnosis often allows individuals to receive educational support, workplace accommodations, and healthcare interventions much sooner.
Autism research continues to evolve beyond older frameworks and labels.
While Professor Simon Baron-Cohen maintains confidence in much of the science behind systemizing and empathizing, he now believes the phrase "extreme male brain" has outlived its usefulness.
The future appears focused less on labels and more on practical outcomes that improve everyday life for autistic people.
Researchers are expanding their attention to physical health, women's health, cardiovascular risks, earlier diagnosis, and community-led priorities. This broader perspective reflects a growing understanding that autism affects many aspects of life beyond cognition alone.
As collaboration between scientists, healthcare providers, and autistic individuals continues to strengthen, future research is likely to produce more inclusive, practical, and meaningful improvements for the autism community.
