Autistic individuals who cannot speak can communicate through 'facilitated communication,' in which a facilitator guides their hand on a keyboard.
In the 1980s-1990s, facilitated communication (FC) emerged as a treatment claiming to unlock hidden literacy and cognitive abilities in non-speaking autistic individuals. Facilitators guided clients' hands on keyboards, and detailed sentences and sophisticated thoughts appeared, thrilling families and therapists. However, controlled double-blind studies revealed the disturbing truth: the facilitator, not the client, was producing the messages. When facilitators couldn't see messages clients were supposedly generating (blind conditions), the generated text became gibberish. When facilitators were told clients saw different images than they actually did, the facilitator's guide produced text matching what facilitators saw, not what was shown to clients. The Rapid Prompting Method (RPM), a related technique, failed similar rigorous testing. Investigations found that FC had enabled false abuse allegations (facilitators unconsciously guided clients to report abuse by suggested questions), and in one case led to criminal charges against innocent parents. FC's persistence despite disconfirming evidence reveals how powerful the desire to unlock 'trapped intelligence' can be, and how unconscious muscular control (ideomotor effect) can fool facilitators and observers. The episode is a reminder that even well-intentioned interventions require controlled validation.
