Why Do Individuals with Autism Find It Hard to Understand Jokes in Social Settings?
Humour connects people, but for many autistic individuals, jokes can feel confusing rather than funny. Understanding a joke often depends on reading between the lines, recognising sarcasm, and interpreting tone or context. These are areas where language and social cognition differ in autism.
Literal Thinking and Language Processing
According to the National Autistic Society, many autistic people interpret language literally and may struggle to understand jokes that rely on wordplay, double meanings, or irony. When humour depends on phrases such as “break a leg” or “nice one” said sarcastically, the mismatch between words and intent can be confusing.
The NICE guideline CG142 notes that adults with autism often experience ongoing difficulties interpreting nonliteral communication, including jokes. These challenges are linked to differences in social cognition and theory of mind, the ability to understand another person’s perspective or intention.
Cognitive and Neurological Factors
Research conducted by Francis and colleagues in 2022, published in Frontiers in Psychology (Francis et al., 2022), found that humour comprehension differences in autism are strongly linked to literal thinking, reduced pragmatic language ability, and weaker central coherence. This means that autistic people often focus on the precise meaning of words rather than the broader social or emotional context, which makes irony and wordplay more difficult to interpret.
Further research carried out by Wang and colleagues in 2024 at Peking University, published in Molecular Autism (Wang et al., 2024), found that autistic adults had particular difficulty understanding jokes that required inference or complex language reasoning. Brain imaging revealed differences in areas responsible for executive function and social cognition, suggesting a neurological basis for why abstract humour is harder to process.
NHS guidance also recognises the environmental challenges that make humour difficult in real time. The NHS explains that sensory overload, anxiety, or fast-paced conversations can make it harder to follow jokes or detect humour cues in social settings.
Practical Ways to Support Understanding
Charities such as Autistica recommend explaining jokes directly, using visual examples, or introducing humour in predictable, structured ways. These approaches help reduce confusion and make social interactions more enjoyable for autistic people.
It is important to note that struggling with certain types of humour does not mean autistic people lack a sense of humour. In fact, research led by Tavassoli and colleagues in 2023, published in the Journal of Autism and Developmental Disorders (Tavassoli et al., 2023), found that many autistic individuals enjoy concrete, visual, or pun-based humour, especially when it does not depend on hidden meaning or social inference.
Takeaway
For autistic people, difficulty understanding jokes stems from differences in language processing, theory of mind, and sensory perception, not a lack of empathy or intelligence. According to NICE guidance and NHS advice, clear, direct communication supports confidence and connection in social settings.
If you or your child are exploring differences in communication, humour, or social understanding, you can arrange a private autism assessment online with Autism Detect.
