The Complex Relationship Between Autism and Empathy

Autistic people do not lack empathy. That claim, repeated for decades in clinical literature and popular culture alike, collapses under the weight of more careful research. What the science actually shows is that empathy is not one thing, and once researchers started measuring its components separately, the supposed deficit either shrank dramatically or disappeared depending on which component they measured. A recent meta-analysis found a large gap in cognitive empathy between autistic and non-autistic people but only a small gap in affective empathy, one that became statistically insignificant when limited to higher-quality studies. The real story is richer and stranger than “autistic people can’t empathize,” and it has reshaped how researchers think about social connection itself.

Two Kinds of Empathy, Two Very Different Findings

The most important distinction in this research is between cognitive empathy and affective empathy. Cognitive empathy is the ability to figure out what someone else is thinking or feeling based on context, facial expressions, tone of voice, and other cues. Affective empathy is the emotional response you have once you know what the other person feels: your gut drops when a friend describes something painful, or you light up when someone shares good news. These are separable brain processes, and they do not always travel together.

When studies lump both types into a single score, autistic people appear to have a large empathy deficit. But that single-score approach is misleading. The meta-analysis that pooled results across many studies found an effect size of roughly −1.70 for unidimensional empathy measures, meaning autistic participants scored well below non-autistic participants. When cognitive and affective empathy were measured separately, the picture changed sharply: cognitive empathy still showed a meaningful gap, but the affective empathy gap was small and, in the best-designed studies, not statistically significant at all.1PubMed Central. A systematic review and meta-analysis of empathy in autism: The influence of measures In other words, the emotional resonance is largely there. What differs is the ability to read the social signals that tell you what someone else is feeling in the first place.

A study of young adults reinforced this split. When researchers used a task-based measure rather than a questionnaire, autistic participants showed no significant difference from non-autistic participants in either cognitive or affective empathy during the task itself. The autistic group did report lower scores on a self-report questionnaire measuring perspective-taking and empathic concern, but the task-based data told a different story.2PubMed Central. Empathic Accuracy and Cognitive and Affective Empathy in Young Adults With and Without Autism Spectrum Disorder This discrepancy between what autistic people do and what they report about themselves turns out to be a recurring theme, and it matters for understanding how empathy gets measured.

The Measurement Problem

How you measure empathy changes what you find. That sounds like a technical footnote, but it is central to this entire topic. Many widely used empathy questionnaires were designed with non-autistic social norms baked in. They ask about behaviors that track social convention as much as emotional engagement: whether you feel comfortable in unfamiliar social situations, whether you notice when someone in a group is being left out, whether you find it easy to predict how people will react. An autistic person might genuinely care about others’ wellbeing but score low on these items because they are about social reading speed, not emotional concern.

The meta-analysis found striking differences even between subscales of the same questionnaire. On one widely used measure, autistic participants scored lower on “empathic concern” (caring about others’ distress) but scored higher on “personal distress” (being overwhelmed by others’ emotions).1PubMed Central. A systematic review and meta-analysis of empathy in autism: The influence of measures That combination is hard to reconcile with a blanket empathy deficit. It looks more like autistic people are absorbing others’ emotions intensely but scoring lower on the subscale that measures the outward, socially recognizable form of caring. Meanwhile, when researchers used neuroimaging tasks and more ecologically grounded assessments, most studies found minimal differences between autistic and non-autistic participants. The tool matters enormously.

When Empathy Feels Like Too Much

Far from feeling too little, many autistic people describe feeling too much. A qualitative study that asked 76 autistic adults about their own empathy experiences found a striking pattern: a high proportion reported hyper-empathic experiences, describing their emotional responses to others’ suffering as overwhelming or even distressing.3PubMed Central. Autistic People’s Experience of Empathy and the Autistic Empathy Deficit Narrative Some participants described absorbing the emotions of people around them to the point where it became difficult to function, particularly in crowded or emotionally charged environments.

This experience of empathic overload is not what most people picture when they hear the word “autism.” It contradicts the popular image so completely that many autistic adults report feeling gaslit by the empathy deficit narrative. They know they feel others’ pain, sometimes more acutely than the non-autistic people around them, yet the cultural script tells them they do not. The disconnect between lived experience and clinical characterization is something autistic writers and advocates have pushed back against for years, and the research is starting to catch up.

Alexithymia, Not Autism, May Drive Emotional Empathy Differences

If affective empathy is largely intact in autism, why do some autistic people still struggle to connect emotionally with others? One answer that has gained substantial research support is alexithymia, a difficulty identifying and describing your own emotions. Alexithymia is not the same thing as autism, but the two overlap frequently: roughly half of autistic people also have elevated alexithymia traits, compared to about one in ten in the general population.

A brain-imaging study found that empathic responses in the anterior insula (a brain region central to feeling others’ pain) were predicted by alexithymia levels in both autistic and non-autistic participants. After accounting for alexithymia, there was no difference in empathic brain activity between the groups. The researchers concluded that empathy differences often attributed to autism may actually stem from this co-occurring trait.4PubMed Central. Empathic brain responses in insula are modulated by levels of alexithymia but not autism A later study of autistic adults confirmed this pattern, finding that atypical emotional empathy appeared to be a feature of alexithymia rather than autism itself.5PubMed Central. Relationships Between Alexithymia, Interoception, and Emotional Empathy in Autism Spectrum Disorder

Work with children points in the same direction. In a study of preadolescents, alexithymia predicted empathy difficulties significantly better than autistic traits did.6PubMed Central. Alexithymia and Autistic Traits as Contributing Factors to Empathy Difficulties in Preadolescent Children This matters practically because alexithymia is potentially more treatable than core autistic traits. If the empathy difficulty comes from trouble recognizing your own emotions rather than from an inability to care about others, that changes what kind of support might help.

The Body’s Role in Reading Emotions

Alexithymia connects to another piece of the puzzle: interoception, or the ability to sense what is going on inside your own body. Emotions are partly physical experiences. You feel anxiety as a tight chest, sadness as heaviness, excitement as a racing heart. If you have difficulty sensing those internal signals, you may also have difficulty identifying the emotion they correspond to, both in yourself and in others.

Research has found that autistic adults show reduced interoceptive sensitivity and reduced interoceptive awareness. Interoceptive awareness was correlated with both empathy and alexithymia, and alexithymia acted as a bridge between the two: poorer body awareness fed into more difficulty labeling emotions, which in turn was linked to lower empathy scores.7PubMed. The Feeling of Me Feeling for You: Interoception, Alexithymia and Empathy in Autism Neuroimaging work has also shown that autistic adults have atypical autonomic responses to others’ pain, with enhanced skin conductance responses and increased activity in the anterior insula, suggesting their bodies are reacting strongly even when their behavioral empathy scores are lower.8PubMed Central. Autonomic and brain responses associated with empathy deficits in autism spectrum disorder The signal is there; the difficulty seems to be in interpreting and channeling it.

How Autistic People Actually Treat Others

If you want to know whether someone cares about other people, one reasonable approach is to look at what they actually do. And when researchers study autistic people’s behavior in moral and prosocial contexts, the results are not what the empathy-deficit narrative would predict.

A large study using a moral foundations framework found that autistic individuals scored the same as non-autistic individuals on “Care,” the dimension measuring concern for others’ welfare. Their affective empathy scores were positively correlated with Care, and this held for both men and women.9PubMed Central. Moral foundations in autistic people and people with systemizing minds In economic games designed to measure generosity, autistic adults were actually more generous than non-autistic adults, particularly toward people they felt less socially close to. They tended to split resources equally regardless of social distance, while non-autistic participants gave less to people they felt further from.10PubMed. Autistic adults show enhanced generosity to socially distant others A follow-up replication confirmed this pattern and ruled out the possibility that autistic participants were simply responding more repetitively or had different attitudes toward money.11PubMed Central. Increased prosocial value orientation in autistic adults

You could frame this as fairness-driven rather than emotionally driven generosity, and that framing may be accurate. But the outcome is the same: autistic people consistently act in ways that benefit others. The notion that empathy difficulties translate into selfish or antisocial behavior is not supported by the evidence.

Autism Versus Psychopathy: An Important Distinction

Because both autism and psychopathy are associated with empathy differences, they sometimes get muddled in popular understanding. The actual profiles are nearly opposite. A systematic review found that psychopathic traits are associated with reduced affective empathy but intact cognitive empathy, while autism shows the reverse pattern: difficulty with cognitive empathy but intact or even heightened affective empathy.12PubMed Central. The relationship between psychopathy and autism: a systematic review and narrative synthesis

A study of boys made this vivid. Boys with psychopathic tendencies reported experiencing less fear and less empathy for victims of aggression, while their ability to figure out what others were thinking was unimpaired. Boys with autism had the opposite profile: they struggled with cognitive perspective-taking tasks but reported emotional experiences and concern for victims that were in line with comparison boys.13PubMed Central. Feeling, caring, knowing: different types of empathy deficit in boys with psychopathic tendencies and autism spectrum disorder In plain terms: the person with psychopathic traits can read you perfectly but does not care; the autistic person cares but may not read you easily. These are fundamentally different situations, and conflating them causes real harm to autistic people.

The Double Empathy Problem

For decades, researchers treated empathy difficulties in autism as a one-directional problem: autistic people fail to understand non-autistic people. The “double empathy problem,” a concept that has gained traction in autism research, flips this framing. It argues that the communication gap runs both ways. Non-autistic people are also poor at reading autistic people’s emotions, intentions, and social signals. The difficulty is mutual, arising from a mismatch between two different styles of social processing rather than from a deficit in one group.

Experimental evidence supports this. When outside observers watched recorded conversations, they rated interactions between two non-autistic people as smoother and more enjoyable than interactions between one autistic and one non-autistic person. But they did not rate interactions between two autistic people as worse than the mixed pairs.14PubMed Central. Non-autistic observers both detect and demonstrate the double empathy problem when evaluating interactions between autistic and non-autistic adults Studies of group interaction confirm the pattern: autistic participants reported more ease and enjoyment when interacting with other autistic adults compared to non-autistic adults, and their sense of rapport declined as more non-autistic people were added to the group. Non-autistic participants’ rapport, by contrast, remained roughly stable regardless of group composition.15PubMed Central. Rapport in same and mixed neurotype groups of autistic and non-autistic adults

Research on social synchrony adds nuance. While physical coordination during conversation (things like mirroring each other’s movements) tends to build rapport in non-autistic pairs, autistic individuals appear to rely less on synchrony for feeling connected.16PubMed. Social motor synchrony and interactive rapport in autistic, non-autistic, and mixed-neurotype dyads This does not mean autistic people do not build rapport; they may simply build it through different channels, ones that researchers are only beginning to study.

Looking at Faces Differently

One commonly cited explanation for cognitive empathy differences is that autistic people process faces differently. There is some truth to this, but the differences are more modest than often assumed. Eye-tracking research on adults watching dynamic emotional facial expressions found that autistic participants did fixate less on the eyes and more on the nose than non-autistic participants. However, all groups, autistic and non-autistic alike, still looked at the eyes more than any other facial region. The overall scanning patterns were described as “stereotypical” across groups, with only modest differences.17PubMed Central. Visual Attention to Dynamic Emotional Faces in Adults on the Autism Spectrum The popular notion that autistic people avoid eye contact entirely and therefore miss all emotional information from faces is an oversimplification of what the data actually show.

Gender, Masking, and the Cost of Performing Empathy

Autistic women and girls are diagnosed later, on average, partly because many of them learn to camouflage their social differences. A systematic review found evidence that camouflaging is an adaptive mechanism used more frequently by autistic females, though it carries negative consequences for mental health and wellbeing.18PubMed. Social Camouflaging in Females with Autism Spectrum Disorder: A Systematic Review Part of this camouflaging involves performing empathic behaviors that match social expectations: nodding at the right moments, producing appropriate facial expressions, using vocal expressiveness to signal engagement. Research has found that autistic females do show more vocal expressiveness than autistic males in social situations, consistent with sex-based differences in masking behavior.19PubMed Central. Camouflaging in Autism: Examining Sex-Based and Compensatory Models in Social Cognition and Communication

The empathy question becomes especially tangled here. An autistic woman who has spent years learning to produce the expected social signals of empathy may score well on observer-rated empathy measures while privately experiencing the interaction as exhausting and effortful. She may genuinely feel empathy, perhaps intensely, but experience the performance of empathy as separate from the feeling itself. Masking makes it harder for researchers to detect the actual empathic experience beneath the learned social behavior, and it makes it harder for the person doing the masking to sustain relationships without burnout.

Empathy Beyond Humans

An interesting piece of the empathy picture involves animals. Many autistic people describe unusually strong bonds with pets and animals more broadly. A large survey of 735 people found that autistic adults were equally attached to their pets as non-autistic adults, though they were less likely to own pets. For autistic participants, pets sometimes served as a compensatory source of social contact, and pet ownership was associated with better mental health outcomes.20PubMed Central. ‘They ask no questions and pass no criticism’: A mixed-methods study exploring pet ownership in autism Some research suggests autistic individuals may even show a bias toward animals over people in empathic responding, though this area is still emerging.

This pattern makes sense in the context of the double empathy problem. Interactions with animals do not require the same rapid-fire social signal processing that human conversation demands. An animal’s emotional state is communicated more simply, and the relationship does not come loaded with the expectations, scripts, and performance demands that make human social interaction taxing for many autistic people. The empathy is there; the channel through which it flows most easily may just be different.

What the Early Theories Got Wrong

Much of the empathy deficit narrative traces back to the “theory of mind” framework proposed in the 1980s, which suggested that autistic people fundamentally lack the ability to attribute mental states to others. That framework shaped decades of research, clinical training, and public perception. Autistic writers and advocates have pushed back against it with increasing force. An analysis of autistic-authored blogs found that contributors described theory of mind not only as empirically questionable but as actively harmful: a framework that framed their social differences as deficiencies and was used to justify interventions aimed at making them appear more “normal” rather than supporting their actual needs.21PubMed. “Unheard minds, again and again”: autistic insider perspectives and theory of mind

The empathizing-systemizing theory, which positions autism as involving weaker empathizing and stronger systemizing, remains influential but has also come under scrutiny. Research in the general population found that the theory’s broad claim holds up to a point: autistic traits do correlate with lower empathizing scores and higher systemizing scores. But the correlations between commonly used autism and empathy questionnaires are “substantially inflated,” and the associations were driven by specific subscales rather than the overall constructs.22PubMed Central. Empathizing and systemizing are differentially related to dimensions of autistic traits in the general population The theory captures something real, but it also oversimplifies, and its influence has contributed to the misleading impression that autism and empathy are incompatible.

Neural Wiring and Social Networks in the Brain

Brain-imaging research has identified specific connectivity patterns that help explain why social processing works differently in autistic people without implying that the emotional capacity is missing. One study found that autistic adults showed partially impaired functional connectivity between the right anterior insula, a region involved in emotional awareness, and key hubs of the default mode network, a brain system associated with social thinking and self-reflection. The impairment was selective: it showed up in brain states most relevant to social and cognitive processing but not across all states.23PubMed Central. Partially impaired functional connectivity states between right anterior insula and default mode network in autism spectrum disorder

This fits a broader picture in which the autistic brain’s social circuitry is wired somewhat differently, making certain types of real-time social computation harder while leaving the underlying emotional responsiveness largely untouched. The wiring difference helps explain why cognitive empathy (which requires rapid social inference) is more affected than affective empathy (which depends more on emotional resonance). It also helps explain why autistic people often report needing more processing time in social situations rather than lacking the capacity to empathize altogether.
