Outdated Science, Real Harm: A Response to Uta Frith
Our response to the claims made by Uta Frith in Tes Magazine.
Published 9 March 2026. Written by Dr. Chris Worfolk.
Uta Frith recently gave an interview entitled "Why I no longer think autism is a spectrum". In the interview, she made some highly controversial comments that have attracted significant attention. In this article, I will address these claims, both in terms of their scientific accuracy and their harmful stereotypes.
Who is Uta Frith?
Frith is a neuroscientist and former professor at University College London (UCL). Her research included exploring differences in theory of mind. While the theory of mind deficit idea is rejected by the autistic community, at the time, it opened up the idea that autism was a brain difference.
She also helped develop the idea of weak central coherence, an early forerunner of monotropism, which we will talk about later in this article.
What did Frith say?
Frith gave an interview to TES, which you can read on their website.
In the article, Frith claims that autism is a disorder, not a difference, and should be treated as such.
She goes on to say that, rather than being a spectrum of presentations, there are two distinct groups: those diagnosed as children with significant impairments, and those diagnosed as adults with limited impairments. She seems, in the view of many readers, to suggest that the latter are not really autistic and instead have social anxiety.
She further goes on to say that there is no scientific basis for masking, and that anyone who can engage in a conversation cannot be autistic. She also claims that very few women and girls are autistic.
Finally, she claims that too much emphasis is placed on subjective experience and not enough on "objective" clinical observation.
Many in the autistic community have been disappointed to see what seem to be the same harmful stereotypes being put forward by someone who claims to be an expert on autism.
However, some may claim that facts don't care about your feelings. So, let's start with the scientific basis for Frith's claims.
A changing philosophy of science
We should be clear from the outset that Frith's comments, however they are presented, are based on her opinions and not on scientific consensus.
Crucially, Frith's claim that we should downplay subjective experience for observational data does not make sense in a modern scientific context.
The way we do science has changed over the decades. To fund a health study today, you typically need to include someone with lived experience in your study design. For example, if you wanted to study diabetes, you would need a diabetic as part of your research team. Here is the UK government's health research strategy:
"Patients and the public must be involved in all stages of the research process: priority setting; defining research outcomes; selecting research methodology; patient recruitment; interpretation of findings and dissemination of results." (2006, Best Research for Best Health)
Second, science does indeed rely on first-hand observation. But as autism is internal: it happens within the brain, the only people capable of doing this first-hand observation are autistic people themselves.
Frith's rejection of what the autistic community are saying puts her in opposition to the community. But it also puts her in opposition to what is considered to be valid research.
Lack of theoretical understanding
Modern autism theory has moved significantly beyond early deficit models. Today, much of autism research is based on monotropism (Murray, Lesser, & Lawson, 2005). This gives us a coherent underlying theory for autism and is widely accepted by the autistic community.
You cannot theorise on autism without talking about ideas such as monotropism, inertia (Buckle et al., 2021), the double empathy problem (Milton, 2012), and internal and external presentations (Bargiela, Steward, & Mandy, 2016).
Naturally, one is free to reject these theories and put forward alternative explanations. But those explanations would also have to explain why these theories are incorrect. Frith's lack of reference to these theories suggests she is simply not familiar with the current autism research.
Ignoring the evidence
There is a large amount of research on masking and camouflaging (Hull et al., 2017; Hull et al., 2020). If Frith wants to claim it has "no scientific basis", she needs to address why there is so much peer-reviewed evidence about it.
Masking is particularly evident in women, who report that it matches strongly with their experience (Hull, Petrides, & Mandy, 2020). So, if Frith wants to dismiss it, she also needs to explain why all of these women are lying, and why so many women with little to gain have independently invented the same experience.
Measuring outcomes
Frith's neurocognitive models of autism have failed to provide significant and meaningful improvements to autistic people's lives. Worse still, the deficit-based approach has had a negative impact on autistic individuals' wellbeing (Pellicano & Houting, 2022).
In contrast, modern theories of autism have made meaningful improvements (Cage, Di Monaco,& Newell, 2018; Davies, Hare, & Walker, 2024). For example, understanding inertia allows us to better cope with transitions. Understanding monotropism allows us to understand the importance of passionate engagement. Understanding sensory differences allows us to build environments where autistic people thrive.
Research can be measured by its truthfulness, and as we have seen, traditional autism research is not based on good science. But it can also be measured in its usefulness, and traditional autism research also fails here.
Words hurt, especially these words
Whether autism is a disorder or a difference might sometimes sound like a scientific question. But, in reality, it is a philosophical question, and how we choose to define it.
We have been here before. Homosexuality was once considered a mental illness. Not because there was anything wrong with them, but because there was a social norm that we "should" be attracted to the opposite sex. Today, we rightly recognise that as nonsense.
Who decides that shallow processing and variable attention is the "right" way to be, and deep processing and fixed attention is the "wrong" way to be? We make that choice when we call something a disorder, and we make the opposite choice when we call something a difference. But that's a choice, not a scientific conclusion. And therefore, to choose to think less of a group of people is plain and simple bigotry.
What science has told us is that if we pathologise it, we do significant damage to autistic individuals' mental health, and when we choose to celebrate it as a difference, we improve the lives of autistic individuals. Those are measurable scientific outcomes.
Summary
Modern theories of autism are grounded in gold-standard science: research that synthesises theory, observation data, and lived experience. Theories like monotropism make predictions about how autistic people would experience the world, and first-hand observational data tells us that these predictions are correct.
Frith's lack of reference to any of these theories suggests that she is simply unaware of current scientific literature on autism, and instead relies on outdated and now defunct research.
This is unfortunate because not only are Frith's opinions unsupported by science, but they are also deeply hurtful to autistic individuals who once again find that their experience is dismissed and ignored.
