Summary: A new study from the University of Edinburgh challenges the widespread belief that autistic people are less effective communicators than non-autistic people. Using a large diffusion-chain experiment (N = 311), researchers found no measurable difference in how accurately information was transmitted within autistic-only, non-autistic-only, or mixed groups. The results indicate that communication difficulties often arise from differences in communication styles and mismatches between neurotypes, rather than from an inherent inability to convey information.
The study highlights that autistic and non-autistic people are equally capable of sharing information successfully. Where interactions feel awkward or less enjoyable, this is more likely due to differences in conversational norms, pace, or nonverbal cues than a deficit in communicative ability. Understanding these style differences can reduce stigma and improve inclusive support and environments.
Key facts
- Equal effectiveness: Autistic and non-autistic participants performed similarly in passing information along a chain.
- Style mismatch: Communication challenges were linked to differences in style and rapport when neurotypes were mixed, not to a reduced ability among autistic people.
- Implications for inclusion: Framing autism as a difference rather than a deficit can reduce stigma and guide better support for autistic communication.
Study overview
The research team from the University of Edinburgh tested how information travels through small chains of people using a diffusion-chain method. Groups were composed entirely of autistic participants, entirely of non-autistic participants, or a mix of both. In each chain, the first person heard a short story from a researcher and then passed what they remembered to the next person; this continued until the final participant recalled the story aloud. Independent scoring measured how much information was retained and transmitted at each step.
Across 311 participants and a range of chains, researchers observed no significant difference in information transfer between single-neurotype and mixed-neurotype chains. This suggests that, in terms of conveying factual or narrative content, autistic and non-autistic people are equally effective communicators.
Experience and rapport
After the task, participants rated how enjoyable and comfortable the interaction felt. Results showed that non-autistic participants generally reported higher rapport with other non-autistic participants, and autistic participants reported higher rapport when interacting with other autistic participants. Disclosing diagnostic status in advance also improved reported rapport. These preference patterns point to the role of shared conversational conventions and mutual understanding in creating smoother social experiences.
Interpretation and significance
The authors argue these findings support a shift away from viewing autism primarily through the lens of social deficit. Instead, autism can be understood as a difference in social communication styles. Recognizing and accommodating diverse communication preferences—rather than attempting to “fix” autistic communication—may lead to better social inclusion, reduced stigma, and more effective support strategies in education, work, and clinical settings.
Funding and collaboration The study was funded by the Templeton World Charity Foundation and involved collaborators from the University of Texas at Dallas, the University of Nottingham, and the University of Glasgow.

Abstract (concise)
Information transfer within and between autistic and non-autistic people
Autism is often clinically described in terms of social communication difficulties, which has fostered the assumption that autistic people are less effective at sharing information. Using a registered diffusion-chain protocol, the study examined information transfer and rapport across autistic, non-autistic, and mixed-neurotype chains (N = 311). Contrary to expectations, no difference in information transfer was observed between single-neurotype and mixed-neurotype chains. Non-autistic chains reported higher rapport overall, and explicitly disclosing diagnostic status improved felt rapport. The findings challenge deficit-based assumptions about autistic communication and emphasize how neurotype mismatches, rather than reduced communicative ability, can undermine social ease.
