In addition, although Cayce's secretary Miss Davis allegedly took down what Cayce said, the records of the readings are jumbled and chaotic. There is nothing to distinguish what Cayce himself independently said, what was the information provided in the letters, and what his handlers – physicians, osteopaths and hypnotists – told him. Thus, researchers cannot say that Cayce ever made an accurate diagnosis without knowing anything about the person at the other end. What is known is that by the time he got some of the letters, the client had already died. Yet Cayce went on with his reading for the individual as though still alive.
