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!

Donald Trump wants to terminate the Environmental Protection Agency - can he?

"Epa, Epa, Eeeepaaaaa" – Grampa Simpson.

 

There have been countless jokes about US President Donald Trump’s aversion to academic work, with many comparing him to an infant. The Daily Show created a browser extension aptly named “Make Trump Tweets Eight Again” that converts the font of Potus’ tweets to crayon scrawlings. Indeed, it is absurd that – even without the childish font – one particular bill that was introduced within the first month of Trump taking office looked just as puerile. Proposed by Matt Gaetz, a Republican who had been in Congress for barely a month, “H.R. 861” was only one sentence long:

“The Environmental Protection Agency shall terminate on December 31, 2018”.

If this seems like a stunt, that is because Gaetz is unlikely to actually achieve his stated aim. Drafting such a short bill without any co-sponsors – and leaving it to a novice Congressman to present – is hardly the best strategy to ensure a bill will pass. 

Still, Republicans' distrust for environmental protections is well-known - long-running cartoon show The Simpsons even did a send up of the Epa where the agency had its own private army. So what else makes H.R. 861 implausible?

Well, the 10-word-long statement neglects to address the fact that many federal environmental laws assume the existence of or defer to the Epa. In the event that the Epa was abolished, all of these laws – from the 1946 Atomic Energy Act to the 2016 Frank R. Lautenberg Chemical Safety for the 21st Century Act – would need to be amended. Preferably, a way of doing this would be included in the bill itself.

Additionally, for the bill to be accepted in the Senate there would have to be eight Democratic senators who agreed with its premise. This is an awkward demand when not even all Republicans back Trump. The man Trum appointed to the helm of the Epa, Scott Pruitt, is particularly divisive because of his long opposition to the agency. Republican Senator Susan Collins of Maine said that she was hostile to the appointment of a man who was “so manifestly opposed to the mission of the agency” that he had sued the Epa 14 times. Polls from 2016 and 2017 suggests that most Americans would be also be opposed to the agency’s termination.

But if Trump is incapable of entirely eliminating the Epa, he has other ways of rendering it futile. In January, Potus banned the Epa and National Park Services from “providing updates on social media or to reporters”, and this Friday, Trump plans to “switch off” the government’s largest citizen-linked data site – the Epa’s Open Data Web Service. This is vital not just for storing and displaying information on climate change, but also as an accessible way of civilians viewing details of local environmental changes – such as chemical spills. Given the administration’s recent announcement of his intention to repeal existing safeguards, such as those to stabilise the climate and protect the environment, defunding this public data tool is possibly an attempt to decrease awareness of Trump’s forthcoming actions.

There was also a recent update to the webpage of the Epa's Office of Science and Technology, which saw all references to “science-based” work removed, in favour of an emphasis on “national economically and technologically achievable standards”. 

Trump’s reshuffle of the Epa's priorities puts the onus on economic activity at the expense of public health and environmental safety. Pruitt, who is also eager to #MakeAmericaGreatAgain, spoke in an interview of his desire to “exit” the 2015 Paris Climate Agreement. He was led to this conclusion because of his belief that the agreement means “contracting our economy to serve and really satisfy Europe, and China, and India”.

 

Rather than outright closure of the Epa, its influence and funding are being leached away. H.R. 861 might be a subtle version of one of Potus’ Twitter taunts – empty and outrageous – but it is by no means the only way to drastically alter the Epa’s landscape. With Pruitt as Epa Administrator, the organisation may become a caricature of itself – as in The Simpsons Movie. Let us hope that the #resistance movements started by “Rogue” Epa and National Parks social media accounts are able to stave off the vultures until there is “Hope” once more.
