Often charlatans (and lawyers) prey on the fact that medicine is inherently uncertain:
Over the next few weeks, Trevor did indeed begin to gain consciousness, an improvement that Debbie took as proof of Dreamhealer’s powers. “The doctors said that he wouldn’t recover, so to me, that’s a miracle,” Debbie said. “It’s a miracle that he’s still alive.” Yet of course medicine is not an exact science; doctors can only go by the patient’s condition at the time of the evaluation, which may change at any moment. Patients may get better or worse for any number of reasons. Doctors’ prognoses are often at least partially wrong, so the simple fact that that Trevor defied one doctor’s expectations and came out of his coma is hardly a miracle.
