Introduction

Rorschach research can be exciting and rewarding, or it can be frustrating and disappointing. Sadly, it is easy to do bad Rorschach research, but that need not be the case. Good Rorschach research is not that difficult, but it does require care. The main problems that confront most Rorschach investigators are created by two elements. First, the test is very complex and much of the data do not fall neatly into so-called normal distributions of scores common to most other psychological tests. Second, Rorschach research is really personality related research and personality is a very intricate psychological phenomenon. Because of this, investigators must be prepared to contend with the difficult issue of individual differences.
