You agree with this column

Martha Gill's Irrational Animals column.

If you’re reading this, chances are you’ve already decided to agree with it. Here’s the curious thing about curiosity: we tend to seek out information that tells us what we already believe. If your politics veer to the left, you’ll conveniently ignore facts that back the right and avoid places that’ll tell you about them. And vice versa.

Throw a quick glance under the nearest article on the Daily Mail website. Dissenting comments nearly always get “rated down”, even if fairly innocuous, or true. Daily Mail readers, it seems, are instantly repelled by information that doesn’t chime with their beliefs. But then, as a liberal, I’m more than happy to believe this – in fact, I only look at the Mail to confirm my prejudices. Here’s why.

Our brains are programmed to construct a robust model of how the world works and then fine-tune it. As we learn, some circuits get hardened and reinforced and some wither away. The hardened circuits are our short cuts. This means that when we’re standing in Starbucks and see a cylindrical, liquid-filled shape on the counter, we don’t have to spend too long working out what it is. One of these short cuts will tell us it’s a cup of coffee.

Deconstructing this edifice too many times takes a huge amount of resources. We’re not designed for endless self-questioning – which is probably why Alain de Botton has, at the time of writing, almost no hair left. Instead, we look for information that builds on the model we have.

While our fact-filtering brains are great for working out where the nearest Americano is, they don’t make for very good political debate. Once people have aligned themselves with a particular party, there’s very little you can do to change their opinion. They’ll simply “select out” your most compelling arguments and merrily continue believing what they believe. We love putting opposing political pundits together in TV debates but when was the last time you saw them reach a consensus?

The mighty Bush

A study published in the journal Political Behaviour shows just how reluctant people are to engage with facts that don’t support their world-view. In the experiment, conducted in 2005, participants were given fake news stories. These news stories were embedded with false facts: that tax cuts under the Bush administration increased government revenues, that weapons of mass destruction had been found in Iraq and that Bush had banned stem-cell research (he only limited some government funding). After each statement, the researchers put in an unambiguous correction – and then tested the participants to see if they picked this up.

They didn’t. Participants who identified themselves as liberal ignored the correction on stem-cell regulations and continued to believe Bush had issued a total ban. Conservatives not only ignored the corrections on Iraq and the tax cuts but clung even more tenaciously to the false information.

If you’re interested in the truth, it turns out the worst thing to do is to assign yourself a “stance” on an issue. The more you care about your cause, the harder it is to properly engage with the arguments of your opponent. In fact, only one thing will improve political debate – we need to stop being passionate about politics.

I'll vote against bombing Isis - but my conscience is far from clear

Chi Onwurah lays out why she'll be voting against British airstrikes in Syria.

I have spent much of the weekend considering how I will vote on the question of whether the UK should extend airstrikes against Daesh/Isis from Iraq to Syria, seeking out and weighing the evidence and the risks.

My constituents have written, emailed, tweeted, facebooked or stopped me in the street to share their thoughts. Most recognised what a difficult and complex decision it is. When I was selected to be the Labour candidate for Newcastle Central I was asked what I thought would be the hardest part of being an MP.

I said it would be this.

I am not a pacifist, I believe our country is worth defending and our values worth fighting for. But the decision to send British Armed Forces into action is, rightly, a heavy responsibility.

For me it comes down to two key questions. The security of British citizens, and the avoidance of civilian casualties. These are separate operational and moral questions but they are linked in that it is civilian casualties which help fuel the Daesh ideology that we cannot respect and value the lives of those who do not believe as we do. There is also the important question of solidarity with the French in the wake of their grievous and devastating loss; I shall come to that later.

I listened very carefully to the Prime Minister as he set out the case for airstrikes on Thursday and I share his view that Daesh represents a real threat to UK citizens. However he did not convince me that UK airstrikes at this time would materially reduce that threat. The Prime Minister was clear that Daesh cannot be defeated from the air. The situation in Syria is complex and factionalised, with many state and non-state actors who may be enemies of our enemy and yet not our friend. The Prime Minister claimed there were 70,000 ground troops in the moderate Free Syrian Army but many experts dispute that number and the evidence does not convince me that they are in a position to lead an effective ground campaign. Bombs alone will not prevent Daesh obtaining money, arms and more recruits or launching attacks on the UK. The Prime Minister did not set out how we would do that, his was not a plan for security and peace in Syria with airstrikes a necessary support to it, but a plan to bomb Syria, with peace and security cited in support of it. That is not good enough for me.

Daesh are using civilian population as human shields. Syrians in exile speak of the impossibility of targeting the terrorists without hitting innocent bystanders. I fear that bombing Raqqa to eliminate Daesh may be like bombing Gaza to eliminate Hamas – hugely costly in terms of the civilian population and ultimately ineffectual.

Yet the evil that Daesh perpetrate demands a response. President Hollande has called on us to join with French forces. I lived in Paris for three years, I spent time in just about every location that was attacked two weeks ago, I have many friends living in Paris now, I believe the French are our friends and allies and we should stand and act in solidarity with them, and all those who have suffered in Mali, Kenya, Nigeria, Lebanon, Tunisia and around the world.

But there are other ways to act as well as airstrikes. Britain is the only G7 country to meet its international development commitments, we are already one of the biggest humanitarian contributors to stemming the Syrian crisis, we can do more not only in terms of supporting refugees but helping those still in Syria, whether living in fear of Daesh or Assad. We can show the world that our response is to build rather than bomb. The Prime Minister argues that without taking part in the bombing we will not have a place at the table for the reconstruction. I would think our allies would be reluctant to overlook our financial commitment.

We can also do more to cut off Daesh funding, targeting their oil wells, their revenues, their customers and their suppliers. This may not be as immediately satisfying as bombing the terrorists but it is a more effective means of strangling them.

The vast majority of the constituents who contacted me were against airstrikes. I agree with them for the reasons I set out above. I should say that I have had no experience of bullying or attempts at intimidation in reaching this decision, Newcastle Central is too friendly, frank, comradely and Geordie a constituency for that. But some have suggested that I should vote against airstrikes to ensure a “clear conscience” ’. This is not the case. There will be more killings and innocent deaths whether there are UK airstrikes or not, and we will all bear a portion of responsibility for them.
