This approach was initially based on a study where 36 convicted serial killers and rapists in American prisons.

Although canter criticises this research and says that aspects of each typology always occur together and that to try and separate them makes a false distinction. It was based on interviews with sex offenders and therefore cannot be generalised to all criminals. It is very deterministic to presume a criminal will easily fall into one of the categories as unanticipated events may happen during the crime which may cause the offender to develop a different pattern. This research cannot be replicated in different countries as it was not a structured method which therefore reduces the
