Literal and overly complicated thinking is associated with specific psychological and neurodevelopmental conditions
Literal and overly complicated or rigid thinking patterns are consistently documented as characteristic features of neurodevelopmental conditions such as autism spectrum disorder.
The retrieved literature consistently supports the association between literal thinking, cognitive rigidity, and neurodevelopmental conditions like autism spectrum disorder. Multiple sources highlight literalism, black-and-white mentality, and concrete or externally oriented cognitive styles as core features of the neurodivergent phenotype, and none of the papers refute this association.

Paper 1 discusses literalism and black-and-white mentality as core facets of cognitive and behavioral rigidity in autism.
