Autism
Autistic Intelligences as Evolutionary Adaptations
Evolutionary psychology models offer strength-based ways to think about Autism.

Key points
- Some cognitive abilities appear to be enhanced in Autism, and Autism seems genetically linked to intelligence.
- These "Autistic traits" include detail orientation, sensory sensitivity, and focus on narrow interests.
- Some "Autistic abilities" may have been selected because they were adaptive in early human environments.
- Evolutionary psychology theories can help as normalize, individualize, and focus on person-environment fit.
Lately, I’ve been exploring evolutionary psychology, especially its perspectives on neurodivergence and Autism. Some researchers in this field—such as Simon Baron-Cohen, Bernard Crespi, and Marco Del Giudice—propose that Autistic traits can be understood not as deficits, but as adaptive intelligences that evolved for specific functions.
These scholars highlight several key observations:
- Certain cognitive abilities appear to be enhanced in individuals on the Autism spectrum.
- Genetic overlaps exist between Autism and high intelligence.
- Autistic traits are disproportionately represented in fields like science, engineering, and information technology.
From an evolutionary standpoint, these observations suggest that some traits commonly associated with Autism may have been positively selected because they offered survival or reproductive advantages in ancestral environments.
These evolutionary psychologists argue that certain traits may have provided a strong advantage in early human activities like hunting and tool-making, and perhaps later in societies defined by agriculture, craftsmanship, and technological innovation. These include:
- Detail orientation
- Systematizing and pattern recognition
- Sensory sensitivity
- Perceptual precision
- Mechanistic thinking
- Bottom-up processing
- Deep knowledge in specialized areas
The idea is that certain niches in human society—especially those requiring precision, innovation, or deep focus—have historically favored these traits. However, when these traits become too intense or imbalanced, or when they co-occur with significant language or cognitive challenges, they may become maladaptive. This provides a useful way to think about similarities and differences between individuals with subclinical autistic traits and Level 1 Autism on the one hand and those with more support-intensive Level 2 or Level 3 presentations on the other.
This idea—that autistic-like traits can be adaptive until they’re not—resonates with something I often say to neurodivergent patients in my practice: “You have superpowers. But (as the Spider-Man movies wisely remind us), with great power comes great responsibility. When, where, and how much you use your powers matters.”
This evolutionary psychology perspective also aligns with some broader psychological findings about human traits:
- Most traits exist on a spectrum rather than being simply present or absent, and are present, more or less, in neurotypical and neurodivergent people.
- Traits often have an adaptive range, with both too little and too much being potentially problematic.
- What’s adaptive in one environment might be maladaptive in another.
I believe that evolutionary psychology can help us:
- Normalize and even appreciate and admire neurodivergence instead of pathologizing it.
- Think in terms of multiple intelligences and strength-based profiles.
- Emphasize person–environment fit, thereby shifting the focus more to accommodations rather than solely on changing individuals.
- See each person as unique and potentially benefiting from truly individualized supports and interventions.
In future blog posts, I look forward to exploring more evolutionary psychology insights on neurodivergence—especially Autism. Stay tuned!
