Background

This is the second study we will be looking at from Making a Profile, as part of your OCR A2 Forensic Psychology course.

The background this study is the same as Hazelwood and Douglas (1980). It is highly recommended that you look that these two studies in series, first studying Hazelwood and Douglas (1980) because this study is an evaluation of  Hazelwood and Douglas (1980)

The background study for this theory, is Holmes and Holmes (1989).

Firstly, what is profiling? Offender or criminal profiling is simply the attempt to predict and create the likely traits and behaviours of an offender of a crime. The likelihood is that you already could begin to have a guess at the type of person that committed a crime. For example three women are found strangled and sexually assaulted at three different, but closely located train stations. It is more than likely that a male committed these offences. Criminal profiling done by professionals is in essence what we just did, but it goes into more depth.

Holmes and Holmes (1989) identified 3 aims of profiling:

The background study for this theory, is Holmes and Holmes (1989).

Later it was found out that his confession was false and he was not guilty of committing the crime. Guðjónsson and Mackeith wondered how such false confessions can arise.

Guðjónsson (1992) suggests there are three types of false confessions:
