The Autism Spectrum May Be Completely Wrong

Why It Matters

Frith’s critique has implications for diagnosis, treatment, research funding and social policy—redefining autism could change who receives services and how resources are allocated. Revisiting diagnostic criteria also affects public understanding and the rights and supports available to autistic people across the severity spectrum.

Summary

In the interview, pioneering psychologist Uta Frith argues that the autism spectrum concept has been diluted over decades, expanding diagnostic criteria and blurring distinctions between profoundly autistic individuals and those newly identified—especially women and girls. Frith traces shifts from psychogenic explanations to cognitive and brain-based approaches, recounting early clinical puzzlement at autistic behavior and the rejection of the "refrigerator mother" theory. She contends that many recent diagnoses share little with classical autism and challenges popular ideas like masking, urging a rigorous re-evaluation of definitions and methods. The conversation raises the question of who should define autism: clinicians, researchers, or autistic people themselves.

Original Description

Autism pioneer Uta Frith wants to dismantle the spectrum. After a career spent grappling with the condition's neural underpinnings, she is unwavering in her controversial call to scrap our current view of it and start again. Frith’s influence on our ever-shifting understanding of autism has been monumental: she developed two landmark theories about how autistic minds might develop differently to neurotypical ones, and was among the first to test ideas like these using newly available brain scanners in the 1990s. Since then, the number of autism diagnoses has sharply risen, especially among women and girls – largely because of a softening and broadening of how we define the condition. But Frith thinks that many people at the milder end of the spectrum have little in common with those who are profoundly autistic. “There’s absolutely no overlap,” she says. “That is the sign that the spectrum isn’t holding.” In this video, she sits down with New Scientist editor Thomas Lewton to discuss autism.
