Violence genes may be responsible for one in 10 serious crimes

Leftists assure us that poverty is the cause of crime.  Could they be wrong?

The genes for extremely violent behaviour have been discovered by scientists who fear they may be responsible for one in 10 serious crimes.

Researchers at the Karolinska Institute in Sweden analysed the genetic make-up of 895 criminals from Finland to see if violence was in their DNA.

The majority of violent crime is committed by a small group of antisocial, repeat offenders, who seem incapable of rehabilitation.

Now scientists believe they have found which genes are responsible for high levels of rage and violence. They believe that they could be responsible for up to 10 per cent of serious crime in Finland.

The criminals who had committed the most serious crimes, such as murder, were found to have variants of two genes; monoamine oxidase A (MAOA) and cadherin 13 (CDH13).

MAOA is linked to dopamine levels in the brain, a chemical which makes people feel happy and fulfilled. CDH13 is linked to impulse control.

“When compared to the control population, non-violent offenders were not observed to exhibit either variant to a greater degree, indicating that these genetic variants may be specific to extremely violent behaviour,” said lead researcher Professor Jari Tiihonen.

The researchers, whose findings were published online in the journal Molecular Psychiatry, also suggest that the low dopamine levels associated with the MAOA gene may make carriers more aggressive when drunk or on drugs, increasing the risk of violent behaviour.

British scientists said the study could help identify potential criminals early when it was still possible to treat their violent tendencies.

However some British researchers criticised claims that the genes could be responsible for such large amounts of crime in Finland.

Prof John Stein, Emeritus Professor of Physiology, University of Oxford, said "This is a very interesting study with plausible aspects.

“But please do not accept the claims that these alleles are 'responsible for 5-10 per cent of violent offences in Finland'. All they show is that they may contribute 5-10 per cent to the chance of an individual being very violent.

“These alleles are quite common and so environmental factors are probably much more important. For instance simply improving prisoners diets can reduce their violent offending by 37 per cent."

Prof Jan Schnupp, Professor of Neuroscience, University of Oxford, added: "Half the people in your office will carry these genes. Odds are 50/50 that you do. How violent has your day been? To call these alleles "genes for violence" would therefore be a massive exaggeration.

“In combination with many other factors these genes may make it a little harder for you to control violent urges, but they most emphatically do not predetermine you for a life of crime.”

Be very afraid. This looks like some means of voodoo testing, mandatory, which will leave certain people at the mercy of some bureaucracy which is usually of a leftist bent. While I don't believe it will allow them to destroy the freedom of soul, the believe in earning and getting ahead, or faith in God, that is most likely what any such effort would directly be diverted toward. And any other crass Godless notions they have.

Watch these people very closely. This is more invasive, false, and more tyrannical than even psychology. And, yes, psychology, today, is merely a leftist ideological tool of a pseudoscience. It is not even close to a science. Hmm... I'm thinking phrenology, and some of the other such "sciences" that were being used to pick winners and losers... and poorly.
