Autism and context blindness

Autism is an extreme form of low-contextual thinking: stimuli, emotions and language are processed literally and fragmentarily. The term context blindness describes the core problem. Every person with autism is unique — the DSM label is a tool, not an explanation.

Sensory intensity: every detail equally sharp and present — For a low-context thinker, every detail is equally prominent — there is no automatic filtering of what is relevant in a given situation.

The term context blindness was originally developed to describe the core problem of autism (Peter Vermeulen, 2011). Autistic individuals often have difficulty using contextual information when interpreting signals and events.

Autism in the DSM

In the DSM-5, autism is described as a disorder with:

limitations in social communication and interaction
limited, repetitive behaviors or interests

Important to emphasize: the DSM is a classification system, not an explanatory model. The label autism only describes a cluster of behaviors and experiences, but says nothing about the unique person.

A well-known saying summarizes this well: If you know one person with autism, you know one person with autism.

Note: In the literature and popular imagination, "typical" characteristics of autism are often mentioned, such as honesty or straightforwardness. Although this is sometimes true, it is not a general rule. People with autism can also lie, for example — often as a coping mechanism to compensate for their context blindness. This illustrates a broader critique of the DSM classifications: they create types and clusters, but do not capture the complexity and uniqueness of the person.

Reframing from the perspective of contextual thinking

Within this project, we see autism not merely as a disorder, but as a variant in thinking style:

low context sensitivity (strongly detail-oriented, difficulty with cohesion and implicit signals)
strengths in accuracy and detail perception
vulnerabilities in relationships, flexibility, and basic trust

Examples of context blindness in autism

Literal interpretation of language ("the train is delayed" → looking at the vehicle instead of the timetable).
Difficulty framing other people's emotions without explicit explanation.
Sensory overload due to noise or social pressure, because filtering irrelevant stimuli is difficult.

Spectrum and overlap

Autism shows overlap with other context-related vulnerabilities:

personality disorders (rigidity, basic trust)
psychoses (when overload leads to reality problems)
depression and burnout (due to constant overcompensation in a complex world)

De Bruin's eight disturbances

Colette de Bruin describes in Dit is autisme (2017, 4th ed. 2023) eight information processing disturbances that accompany autism. From a Context Thinking perspective, they can be read as eight manifestations of context blindness:

Processing information in fragments — the trees, not the forest.
Not recognizing social information — emotional and implicit signals are missed.
Making incorrect connections — cause-and-effect relationships are stored incorrectly.
Over- or under-reacting — sensory stimuli are insufficiently filtered.
Difficulty with meaning-making — literal interpretation, longer processing time.
Storing information chaotically — retrieval costs disproportionately much energy.
Missing frames of reference — insufficiently developed social and factual frameworks.
Not discarding information — working memory fills up due to lack of automatic filtering.

The common denominator: each of these disturbances is understandable as a manifestation of reduced context integration. The disturbances are the cause; context blindness is the cognitive consequence — two complementary descriptions of the same phenomenon.

De Bruin also proposed the Circle of Autism Spectrum Symptoms as an alternative to the linear spectrum model: autism is not a point on a line, but a multidimensional profile. See The multidimensional profile for the full elaboration.

The eight disturbances are a practical framework by De Bruin, not a scientifically validated diagnostic model. Source: Bruin, C. de & Naber, F.B.A. (2023). Dit is autisme. Van hersenwerking tot gedrag (4th ed.). Doetinchem: High 5 Publishers.

Autism and high sensitivity: confusion in two directions

In care settings the word "highly sensitive" is sometimes used instead of — or even to rule out — an autism diagnosis: "it is not autism, it is high sensitivity." But that is not how it works. High sensitivity is not a recognized diagnosis (not in the DSM-5-TR, not in the ICD-11), and so it cannot rule out a real diagnosis.

The confusion also works in two directions. A sensitive, high-contextual child that reacts strongly to atmosphere and tension can be wrongly seen as autistic. Greven and colleagues (2019) point this out: sensitive children can withdraw in a demanding environment, and that then looks like autism — while it is not.¹²

Beneath the popular HSP word hide at least three different patterns. One looks like autism (quickly overstimulated). One is the opposite of autism (deep processing, sensitive to atmosphere). And one is sensitivity on top of a difficult history. None of the three is a diagnosis. Read the full elaboration on High sensitivity: one word, three stories.

Conclusion

Autism can be understood as an extreme form of low-contextual thinking. Classifying it as a "disorder" helps in healthcare practice but should not be confused with an explanation or with the person themselves. Every person with autism is unique, with their own strengths, vulnerabilities, and ways of dealing with context.
