Despite the FC community's reluctance to participate in testing, researchers outside the community set up blinded experiments to identify who was doing the communicating. Some of the tests were conducted as a direct response to cases involving sexual abuse allegations made through facilitated communication against parents, teachers, and caregivers of people with disabilities. However, a number of controlled evaluations were also conducted by clinicians, researchers, and program administrators who were considering the use of FC, but wanted an objective, empirical basis for deciding what role, if any, FC would have in their programs.
