I believe you should provide some evidence for such claims. Like I said the wikipedia entry(to which you linked) contains mixed data.

There are some positive data, like: "A study by Bernadi and Tuzzi finding that the communication of FC users displayed the characteristics of valid communication recorded that of its 50 subjects 13 had achieved “full and independent control of the method” while 37 “had reached a high level of independence”"

I disagree: The facilitator may be as shocked and horrified as anyone.
