Facilitated communication
Facilitated communication (FC), or supported typing, is a scientifically discredited technique that claims to allow non-verbal people, such as those with autism, to communicate. The technique involves a facilitator guiding the disabled person's arm or hand in an attempt to help them type on a keyboard or other such device which they are unable to properly use if unfacilitated.There is widespread agreement within the scientific community and among disability advocacy organizations that FC is a pseudoscience. Research indicates that the facilitator is the source of the messages obtained through FC, rather than the disabled person. The facilitator may believe they are not the source of the messages due to the ideomotor effect, which is the same effect that guides a Ouija board. Studies have consistently found that FC is unable to provide the correct response to even simple questions when the facilitator does not know the answers to the questions (e.g., showing the patient but not the facilitator an object).
