The concept of neurodiversity emerged from the autistic community in the 1990s — not from academia, not from clinicians, but from autistic and neurodivergent people describing their own experience and organizing around it.
The online community InLv (Independent Living on the Autism Spectrum), founded by Martijn Dekker, was one of the primary spaces where this thinking developed. Jim Sinclair's foundational essay "Don't Mourn For Us" (1993) and the work of Autism Network International laid the groundwork. The ideas were built through collective lived experience.
This history matters. The paradigm was not handed down from above. It was built from the inside — by the people it describes, from their own understanding of themselves. That is its authority.
