The Spellers movie showed that using gross motor function to help nonverbal autistic. People spell is a miracle and the New York Times should be ashamed of themselves.

Multiple studies across ages, settings and populations have failed to validate FC under controlled conditions. These findings have been replicated repeatedly (https://journals.sagepub.com/doi/10.1177/002246699502800403). Anecdotal reports and case claims have not held up under rigorous controlled testing, which is the standard for establishing efficacy.

The strongest evidence (of non-efficacy) comes from multiple large message-passing (blinded) experiments - FC does not reliably demonstrate independent communication by the autistic person; https://link.springer.com/article/10.1007/BF02172232

Multiple major reviews have summarized a large body of negative evidence, not merely isolated failures. For example - https://journals.sagepub.com/doi/10.1177/1053451217692564

The consistent finding is that apparent success occurs only when facilitators can influence responses. Research and analyses point to the ideomotor effect as the reason why FC can FEEL SUBJECTIVELY CONVINCING despite failing to show efficacy in objective evaluations. Facilitators can unconsciously guide movements, similar to Ouija board effects.

Studies generally show autistic subject output depends critically on “mental support” from the facilitator rather than the autistic subject's independent ability - https://journals.sagepub.com/doi/10.1177/1362361398024005

In a rare case of near-unanimous consensus across disciplines, all major scientific, clinical and professional organizations are aligned. The American Speech-Language-Hearing Association states FC has no scientific evidence of validity, and strong evidence that facilitators author the messages (https://www.asha.org/policy/ps2018-00352). Other professional bodies (e.g., speech-language and clinical organizations internationally) similarly conclude there is no reliable evidence of efficacy (https://www.rcslt.org/members/delivering-quality-services/facilitated-communication).

Beyond lack of efficacy, DOCUMENTED RISKS include false attribution of communication (misrepresenting the autistic person's views), false allegations (including abuse claims generated via FC) and diversion from (known to be) effective interventions.
