I vaguely recall a story that Penn and Teller used an actress to portray a medium using cold reading to show that it is indeed a load of cobblers.A woman who received a favorable reading was told afterwards that it was a scam but refused to believe it even when it was explained how it was done.This was referred to as the Henrietta syndrome. A friend asked me where I got this information from and I don't seem to be able to find a link anywhere.Can anybody help or have I dreamt it?Harry
