A new information-theory framework proposes that insistence on sameness in autism is an attempt to minimize surprise and uncertainty, redefining autism as a cognitive style restricted to discrimination, memorization, and prediction of tangible properties.
The research
Przemysław Śliwiński, an independent researcher, published the framework in Frontiers in Computational Neuroscience (2026, Vol. 19, Article 1714428) and as a preprint on arXiv (arXiv:2608.04616, submitted 5 Aug 2026). The work is theoretical, spanning 11 pages with 2 figures, and draws on information theory to model behavior.
Śliwiński introduces a metric: DH(R, M) = H(R|M) + H(M|R), where R represents sequences of random stimuli and M is memory that stores and retrieves them. H(.|.) denotes conditional entropies, interpreted as surprise and uncertainty. To minimize this metric, an individual can either learn about R and store it in M, or restrict R to what is already known in M. The author concludes that insistence on sameness is a manifestation of the latter strategy—constraining the environment to match existing memory.
The framework quantifies concepts like sensory overload, deprivation, anxiety, comfort zone, disappointment, disorientation, pedantry, and rigidness. It also yields guidelines for learning therapies and daily care routines, which can be defined as optimization algorithms and implemented in robotic caregivers. Validation is proposed via a Turing test-like approach that requires no experiments involving individuals with autism.
Why it matters
This model offers a formal, testable way to understand a core feature of autism—not as a deficit but as a rational strategy to reduce uncertainty. For anyone interested in cognition, it highlights how memory and prediction shape behavior. It also suggests that tailoring environments to reduce unpredictability may support learning and self-reliance. The framework could inform therapies that gradually expand comfort zones rather than forcing change, and it provides a common language for researchers, caregivers, and engineers.
What you can do
- Notice your own uncertainty: Pay attention to when you seek routine or predictability. It may be your brain minimizing entropy.
- Expand gradually: If you want to build cognitive flexibility, introduce small, controlled changes to daily routines—one at a time.
- Use memory strategically: Learning new patterns can reduce surprise. Try a brain-training exercise that challenges prediction and recall.
- Respect different strategies: Understand that some people manage uncertainty by creating sameness, and that this can be adaptive.
These insights align with evidence-based approaches to cognitive training, which emphasize progressive challenge and feedback.
