Powerful as the routine is, this is not a Q&A. In a Q&A, the participants think of questions
(typically about the participants' futures) and the mentalist apparently reveals answers to those
questions.
The Three Types is a mind reading act in which the performer appears to use
great powers of psychological analysis to read minds. It is a great book for those who like patter
relating to psychology (like what Derren Brown does) and I may use this book if I ever go in that
direction. As of now, this book is not for me. I believe it dilutes the power and appeal of an act
to explicitly announce you are not psychic.
