"Anyone considering, or already studying psychology will have to learn about and understand research methods and statistics. The fact that research methods and statistics is nearly always compulsory should immediately alert you to its importance. In order to critcally evaluate the findings of key studies you need to be aware of how the data supporting those findings came about; and you can't seriously hope to conduct your own research with confidence unless you have a clear idea how to design, execute and analyse your investigation. When I first started supervising research dissertations and psychology projects I came across a large number of students who refused to consider doing anything other than indepth interviews, whether such an approach was appropriate for their particular invesigation or not. The most common reason for this was the incorrect assumption that qualitative research methods (text based) are much easier to understand and carry out proficiently than Quantitative (number based) research methods.

"Case histories make contributions to science and practice, but they can also be highly misleading. We illustrate with our re-examination of the case of Jane Doe; she was videotaped twice, once when she was six years old and then eleven years later when she was seventeen. During the first interview she reported sexual abuse by her mother. During the second interview she apparently forgot and then remembered the sexual abuse. Jane's case has been hailed by some as the new proof of recovery of repressed or dissociated traumatic memories, and even as proof of the reliability of recovered memories of repeated abuse. Numerous pieces of "supporting evidence" were given in the original article for believing that the abuse occurred. Upon closer scrutiny, however, there are reasons to doubt not only the "supporting evidence," but also that the sexual abuse ever happened in the first place. Our analysis raises several general questions about the use of case histories in science, medicine, and mental health. There is a cautionary tale not only for those professionals who advance the case history, but also for those who base their theories on it or would readily accept it as proof."
