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!

Inside a shaken city: "I just want to be anywhere that’s not Manchester”

The morning after the bombing of the Manchester Arena has left the city's residents jumpy.

On Tuesday morning, the streets in Manchester city centre were eerily silent.

The commuter hub of Victoria Station - which backs onto the arena - was closed as police combed the area for clues, and despite Mayor Andy Burnham’s line of "business as usual", it looked like people were staying away.

Manchester Arena is the second largest indoor concert venue in Europe. With a capacity crowd of 18,000, on Monday night the venue was packed with young people from around the country - at least 22 of whom will never come home. At around 10.33pm, a suicide bomber detonated his device near the exit. Among the dead was an eight-year-old girl. Many more victims remain in hospital. 

Those Mancunians who were not alerted by the sirens woke to the news of their city's worst terrorist attack. Still, as the day went on, the city’s hubbub soon returned and, by lunchtime, there were shoppers and workers milling around Exchange Square and the town hall.

Tourists snapped images of the Albert Square building in the sunshine, and some even asked police for photographs like any other day.

But throughout the morning there were rumours and speculation about further incidents - the Arndale Centre was closed for a period after 11.40am while swathes of police descended, shutting off the main city centre thoroughfare of Market Street.

Corporation Street - closed off at Exchange Square - was at the centre of the city’s IRA blast. A postbox which survived the 1996 bombing stood in the foreground while officers stood guard, police tape fluttering around cordoned-off spaces.

It’s true that the streets of Manchester have known horror before, but not like this.

I spoke to students Beth and Melissa who were in the bustling centre when they saw people running from two different directions.

They vanished and ducked into River Island, when an alert came over the tannoy, and a staff member herded them through the back door onto the street.

“There were so many police stood outside the Arndale, it was so frightening,” Melissa told me.

“We thought it will be fine, it’ll be safe after last night. There were police everywhere walking in, and we felt like it would be fine.”

Beth said that they had planned a day of shopping, and weren’t put off by the attack.

“We heard about the arena this morning but we decided to come into the city, we were watching it all these morning, but you can’t let this stop you.”

They remembered the 1996 Arndale bombing, but added: “we were too young to really understand”.

And even now they’re older, they still did not really understand what had happened to the city.

“Theres nowhere to go, where’s safe? I just want to go home,” Melissa said. “I just want to be anywhere that’s not Manchester.”

Manchester has seen this sort of thing before - but so long ago that the stunned city dwellers are at a loss. In a city which feels under siege, no one is quite sure how anyone can keep us safe from an unknown threat

“We saw armed police on the streets - there were loads just then," Melissa said. "I trust them to keep us safe.”

But other observers were less comforted by the sign of firearms.

Ben, who I encountered standing outside an office block on Corporation Street watching the police, was not too forthcoming, except to say “They don’t know what they’re looking for, do they?” as I passed.

The spirit of the city is often invoked, and ahead of a vigil tonight in Albert Square, there will be solidarity and strength from the capital of the North.

But the community values which Mancunians hold dear are shaken to the core by what has happened here.
