The double empathy problem is a theory proposing that communication difficulties between autistic and non-autistic people are not caused by a deficit in autistic people alone, but by a two-way mismatch in communication styles and understanding. First described by researcher Damian Milton in 2012, the idea reframes a decades-old assumption: that autistic people simply lack the ability to understand others. Instead, it suggests that non-autistic people struggle equally to understand autistic people, and that the real problem lives in the gap between two different ways of experiencing the world.
The Old View: A One-Sided Deficit
For most of modern psychology, the dominant explanation for why autistic people face social challenges has been “theory of mind.” This model proposes that autistic individuals have an impaired ability to infer what other people are thinking or feeling, sometimes described as lacking cognitive empathy. Within this framework, the social difficulties autistic people experience are treated as something broken inside the individual, a missing or dysfunctional mental mechanism that non-autistic people possess naturally.
This deficit framing shaped decades of research, clinical practice, and popular understanding. It’s the origin of the widespread belief that autistic people “lack empathy,” a claim that has been heavily challenged in recent years. Researchers now generally distinguish between cognitive empathy (understanding what someone else might be thinking) and affective empathy (feeling concern or emotional resonance with others). Evidence suggests autistic people may process cognitive empathy differently but do not lack affective empathy. The double empathy problem takes this further by questioning whether the cognitive gap is really one-sided at all.
What the Double Empathy Problem Actually Says
The core idea is straightforward: when two people with very different ways of experiencing the world try to communicate, both sides struggle to understand each other. The formal definition describes it as “a disjuncture in reciprocity between two differently disposed social actors” who hold different norms and expectations. In plain terms, autistic and non-autistic people often have different communication styles, different social expectations, and different ways of expressing themselves. When those styles collide, neither person fully grasps what the other means or feels.
This is a significant shift. Rather than treating empathy as an individual cognitive ability that some people have and others lack, the double empathy framework treats it as something that emerges between people. It depends on shared context, mutual understanding, and a degree of overlap in how two people see the world. When that overlap is small, communication breaks down on both sides, not just one.
A key consequence of this framing: the social difficulties autistic people face in mixed interactions are expressions of empathy differences, not empathy deficiencies. The problem isn’t located inside the autistic person. It’s located in the interaction itself.
The Evidence Behind the Theory
The most striking evidence comes from research comparing how well information travels between different pairings of people. In a widely cited study by Catherine Crompton and colleagues, participants played a version of the telephone game, passing a story from one person to the next in chains. Some chains were all autistic people, some were all non-autistic people, and some were mixed. The results were clear: autistic people transferred information to other autistic people just as effectively as non-autistic people did with each other. The quality of information sharing only broke down when one person in the pair was autistic and the other was not. Interpersonal rapport followed the same pattern, higher within same-neurotype pairs and lower in mixed pairs.
This finding directly challenges the idea that autistic people have a blanket social communication deficit. If that were the case, autistic-autistic pairs should also struggle. They don’t. The difficulty appears specifically at the point where two different neurotypes meet. A larger follow-up study with 311 participants, published in Nature Human Behaviour, found a more nuanced picture, with no significant difference in information transfer between single-neurotype and mixed-neurotype chains. This suggests the effect may depend on the specific communication context, but the broader principle that autistic social ability is intact in compatible settings has held up across multiple studies.
Why This Matters for Autistic People
The practical stakes of this reframing are real. When social difficulty is treated as an individual deficit, the burden falls entirely on the autistic person to adapt, mask, and perform social behaviors that feel unnatural. Autistic people are a socially marginalized group exposed to significant stigma and minority stress. They report high levels of unwanted loneliness across the lifespan and lower quality of life compared to non-autistic peers.
Research shows that this stigma and stress can be reduced in autistic company. When autistic people interact with other autistic people, rapport improves and communication flows more naturally. The double empathy framework helps explain why: it’s not that autistic people can’t connect, it’s that they connect differently. Disproportionately blaming the autistic person for mixed-interaction breakdowns contributes to real-world exclusion, victimization, and discrimination. Non-autistic observers in studies have been shown to both detect and demonstrate the double empathy problem, rating mixed interactions as lower in quality while simultaneously undervaluing the autistic participant’s contributions.
Bridging the Gap in Practice
If the communication difficulty is genuinely two-sided, then the responsibility to bridge it should be shared. In workplaces, for example, research on the double empathy problem points toward a need for “cultural humility” on the part of non-autistic colleagues and managers. This means recognizing that autistic communication styles are different rather than deficient, and that misunderstanding someone’s behavior is not the same as that person behaving incorrectly.
Practically, this looks like adapting environments rather than trying to fix individuals. Instead of training autistic employees to mimic non-autistic social norms, workplaces that embrace neurodiversity focus on fostering understanding of different communication preferences, being explicit about expectations rather than relying on unspoken social rules, and creating space for autistic people to work and socialize in ways that suit them. Research in this area suggests that changing the social culture of a workplace to welcome neurodiverse ways of being leads to longer, broader, and more successful career outcomes for autistic adults.
The same principle applies in schools, healthcare settings, and personal relationships. When non-autistic people make an effort to learn how autistic people communicate, rather than assuming the autistic person should do all the adapting, both sides understand each other better. The double empathy problem isn’t a niche academic concept. It’s a practical lens for understanding why certain conversations feel harder than they should, and what both people can do about it.
