I'm curious as to what causes someone to be criminally insane. I'm just going to go out on a limb and say that it stems from child abuse. In which case, lets bring the next generation's ACE scores down and play the lifeboat scenario by ear.
That is one way to majorly oversimplify things. In evaluating the causes for and the genesis of any psychological condition, you have to look at the etiology perhaps a bit more before blindly stating child abuse. For a start it is extremely unlikely that child abuse would be an only cause. There is always going to be some kind of genetic predisposition to something like schizophrenia which can lead a person to be considered criminally insane. That is your ''necessary cause''
In mental illness it helps to look at whether things are:
necessary cause
Sufficient cause
distal causal factor
Proximal causal factor
Reinforcing contributory cause
If you can find more than one causal event or indicator you can start to build a pattern but it is rare to find a simple cause and effect chain. Instead there will be complex interactions between the causal chains.
Once you've established some kind of rigorous method of evaluating a persons problem then whilst looking at the biological possibilities in the neccessary or sufficient causes you can look at environmental influences. Early deprivation, trauma, marital discord, bad parenting or parental psychopathology.
We love to chuck around the word abuse but the fact is there is a possibility that psychologically neglect may be worse than abuse for extremely young infants, I don't think it is just abuse we should worry about. One thing is certain is that for the young they may never overcome these childhood difficulties, It would be nice if education taught some basic coping skills instead of say a language they'll never need to speak or some other useless 5 year endeavour of no benefit.
So that is certainly one environmental factor but there are more, Mental illness has been tied to societal and cultural contexts, prejudice and discrimination, uncertainty, density, urban stress. Unemployment has been shown to have a huge impact, correlate that with the prevalence of mental illness in welfare dependant groups and you will see a trend.
I'm also intrigued by the findings that violent blows to the head can cause mental problems such as instability in the excitatory controls in the seretonin complex. Leading to violent or suicidal urges, as little as 5-7 violent blows could induce this kind of problem.
