I see a boat, you see a sandwich
I wondered as soon as I read or heard (I forget which) that the coma guy was communicating by typing with the help of his caregiver. Uh oh, I thought. No he isn’t. If he’s doing it with someone else’s ‘help,’ then he’s not doing it. This has been tested. It’s the clever Hans effect. The ‘helper’ or ‘facilitator’ does the typing.
James Randi had the same thought, and he saw some video which further gave the game away. He finds it all very irritating.
NARRATOR: The facilitator and autistic individual sat side by side, with a screen dividing their visual field. Sometimes they were shown the same picture, sometimes different ones. They tested 12 clients facilitating with 9 staff members, many who were trained in Syracuse. They ran dozens of trials. The results were shocking.
Not one correct answer. Not one. It was Clever Hans.
