Is there really a “liberal gene”?

New research suggests there might be. I’m sceptical.

From a press release from the Cambridge University Journal of Politics:

Liberals may owe their political outlook partly to their genetic make-up, according to new research from the University of California, San Diego, and Harvard University. Ideology is affected not just by social factors, but also by a dopamine receptor gene called DRD4. The study's authors say this is the first research to identify a specific gene that predisposes people to certain political views.

Appearing in the latest edition of the Journal of Politics published by Cambridge University Press, the research focused on 2,000 subjects from the National Longitudinal Study of Adolescent Health. By matching genetic information with maps of the subjects' social networks, the researchers were able to show that people with a specific variant of the DRD4 gene were more likely to be liberal as adults, but only if they had an active social life in adolescence.

Dopamine is a neurotransmitter affecting brain processes that control movement, emotional response, and ability to experience pleasure and pain. Previous research has identified a connection between a variant of this gene and novelty-seeking behaviour, and this behaviour has previously been associated with personality traits related to political liberalism.

Lead researcher James H Fowler of UC San Diego and his colleagues hypothesised that people with the novelty-seeking gene variant would be more interested in learning about their friends' points of view. As a consequence, people with this genetic predisposition who have a greater-than-average number of friends would be exposed to a wider variety of social norms and lifestyles, which might make them more liberal than average. They reported that "it is the crucial interaction of two factors – the genetic predisposition and the environmental condition of having many friends in adolescence – that is associated with being more liberal". The research team also showed that this held true independent of ethnicity, culture, sex, or age.

Professor Fowler concludes that the social and institutional environment cannot entirely explain a person's political attitudes and beliefs and that the role of genes must be taken into account: "These findings suggest that political affiliation is not based solely on the kind of social environment people experience."

I'm sceptical. Scientists seem to be able to find a gene for everything these days!

In the race to be France's next president, keep an eye on Arnaud Montebourg

Today's Morning Call. 

Good morning. As far as the Brexit talks are concerned, the least important voters are here in Britain. Whether UK plc gets a decent Brexit deal depends a lot more on who occupies the big jobs across Europe, and how stable they feel in doing so.

The far-right Freedom Party in Austria may have been repudiated at the presidential level but they still retain an interest in the legislative elections (due to be held by 2018). Both Lega Nord and Five Star in Italy will hope to emerge as the governing party at the next Italian election.

Some Conservative MPs are hoping for a clean sweep for the Eurosceptic right, the better to bring the whole EU down, while others believe that the more vulnerable the EU is, the better a deal Britain will get. The reality is that a European Union fearing it is in an advanced state of decay will be less inclined, not more, to give Britain a good deal. The stronger the EU is, the better for Brexit Britain, because the less attractive the exit door looks, the less of an incentive to make an example of the UK among the EU27.

That’s one of the many forces at work in next year’s French presidential election, which yesterday saw the entry of Manuel Valls, the French Prime Minister, into the race to be the Socialist Party’s candidate.

Though his star has fallen somewhat among the general public from the days when his opposition to halal supermarkets as mayor of Evry, and his anti-Roma statements as interior minister made him one of the most popular politicians in France, a Valls candidacy, while unlikely to translate to a finish in the top two for the Socialists could peel votes away from Marine Le Pen, potentially allowing Emanuel Macron to sneak into second place.

But it’s an open question whether he will get that far. The name to remember is Arnaud Montebourg, the former minister who quit Francois Hollande’s government over its right turn in 2014. Although as  Anne-Sylvaine Chassany reports, analysts believe the Socialist party rank-and-file has moved right since Valls finished fifth out of sixth in the last primary, Montebourg’s appeal to the party’s left flank gives him a strong chance.

Does that mean it’s time to pop the champagne on the French right? Monteburg may be able to take some votes from the leftist independent, Jean-Luc Mélenchon, and might do some indirect damage to the French Thatcherite Francois Fillon. His supporters will hope that his leftist economics will peel away supporters of Le Pen, too.

One thing is certain, however: while the chances of a final run-off between Le Pen and Fillon are still high,  Hollande’s resignation means that it is no longer certain that the centre and the left will not make it to that final round.

THE SOUND OF SILENCE

The government began its case at the Supreme Court yesterday, telling justices that the creation of the European Communities Act, which incorporates the European treaties into British law automatically, was designed not to create rights but to expedite the implementation of treaties, created through prerogative power. The government is arguing that Parliament, through silence, has accepted that all areas not defined as within its scope as prerogative powers. David Allen Green gives his verdict over at the FT.

MO’MENTUM, MO’PROBLEMS

The continuing acrimony in Momentum has once again burst out into the open after a fractious meeting to set the organisation’s rules and procedures, Jim Waterson reports over at BuzzFeed.  Jon Lansman, the organisation’s founder, still owns the data and has the ability to shut down the entire group, should he chose to do so, something he is being urged to do by allies. I explain the origins of the crisis here.

STOP ME IF YOU’VE HEARD THIS ONE  BEFORE

Italy’s oldest bank, Monte Paschi, may need a state bailout after its recapitalisation plan was thrown into doubt following Matteo Renzi’s resignation. Italy’s nervous bankers will wait to see if  €1bn of funds from a Qatari investment grouping will be forthcoming now that Renzi has left the scene.

BOOM BOOM

Strong growth in the services sector puts Britain on course to be the highest growing economy in the G7. But Mark Carney has warned that the “lost decade” of wage growth and the unease from the losers from globalisation must be tackled to head off the growing tide of “isolation and detachment”.

THE REPLACEMENTS

David Lidington will stand in for Theresa May, who is abroad, this week at Prime Ministers’ Questions. Emily Thornberry will stand in for Jeremy Corbyn.

QUIT PICKING ON ME!

Boris Johnson has asked Theresa May to get her speechwriters and other ministers to stop making jokes at his expense, Sam Coates reports in the Times. The gags are hurting Britain’s diplomatic standing, the Foreign Secretary argues.
