The issue of human touch, and the importance of it for infant development, was really demonstrable in Britain in WWII. The infants who were moved to more safe places, such as nurseries, were found to have a nearly 33% mortality (death) rate.

This was before programs were in place to provide cuddling, holding and interaction rather than having the infants just lie in their cots all day except for feeding times. So, if we tried to say that lack of touch, or abusive touch, could lead to serial killer development, I would have expected a peak in serial killings in the 60-70's.

Another experiment was done in the 20's when behaviourists would have their children without stimulation, and those experiments did not produce serial killers either. So, although some environmental factors may contribute to the further development of serial killers, it is the biologic/genetic core that makes them.

It is not a belief that I feel abuse is not causative, but the statistical analysis of them to date have shown no greater incidence of abuse than in the general population.

As far as Aileen Wuornos is concerned, her genetic makeup was more male than female. The statistics also show that men are serial killers, the Y chromosome changes, and that is an area which we are studying now.
