What if psychologists ruled the world? In real life?

Baby blue eyed boozers get bossed

Mexican faceApparently blue eyed people are seen as less dominant than brown-eyed people – regardless of whether or not they are attractive (see my earlier post; Take me to your (tall and probably attractive) leader).

But it’s not just because of the eye colour. Czech researchers think it might be because people with blue eyes are treated as children longer and become conditioned to being more submissive.

And according to economics writer Chris Dillow in The Times (2/6/10): binge-drinking is more common in northern than southern Europe. Researchers at the Universities  of Oslo and Wyoming say that it’s in the genes and because blue-eyed people, more common in the North, are shyer they drink more to loosen their inhibitions.

Back in December 2010 it was reported that Scientists had discovered a gene, HTR2B, which can make people more susceptible to bouts of sudden aggression when under the influence of alcohol. Research with violent criminals in Finnish prisons found they were three times more likely to carry an abnormal variant of the gene than ordinary people.

Although not the full answer as to why people engage in spontaneous and motiveless violence it explains how it can be triggered by other genetic and environmental factors.

This Q20* gene mutation is only found in Finns, and in only 1% of them, and as most of whom are not violent so there is no point in screening for it.

And it doesn’t explain what happens in the UK. But research at the US National Institute on Alcohol Abuse and Alcoholism published in Nature shows that genetic factors coupled with drug and alcohol abuse can lead to impulsivity and spontaneous violence.

The Finns were chosen for the prison study because they are genetically distinct but they also appear to have problems with depression and drinking, maybe due to the long hours of darkness. The first time I was in Helsinki it was still Winter yet there were a number of people lying in the streets in a drunken stupour in the freezing cold. Passers-by just checked to see if they were OK and moved on as if it were quite normal.

And the last time I was in Helsinki wandering round a supermarket I couldn’t find the section for wines and spirits. I eventually asked a local who pointed me to a separate Alco section (the beer was with the bottled water so it shows their take on what constitutes an alcoholic drink)She explained that it was for their own good as alcohol-related problems are in their genes. Seems like she was right.

Despite that particular problem Finland is one of the most highly rated countries in the world on a range of measures and a popular one for people who want to live elsewhere.
