Beware groupthink

The perils of “following the crowd” in this unpredictable election.

Yesterday, I flagged up Alex Barker's "unpacking" of the consensus view among Britain's top pollsters that the Tories will indeed secure a Commons majority on 6 May -- despite a narrowing in the polls.

Writing on the FT blog, Alex pointed out that "a unanimous consensus is always something to be wary of, particularly when it doesn't quite reflect the evidence available".

Today, the excellent Aditya Chakrabortty has a piece in the Guardian dissecting the cult of the "expert commentator" and dismissing the "high-intensity forecasting" of the nation's political pundits as "largely worthless".

Aditya writes:

Cast your mind back to June last year, when yet another Labour putsch was being launched against the Prime Minister. Trawling through the comment pages published in the week when the coup was at its height -- with ministers resigning, and local and European elections looming -- I found 20 columns and leading articles in the Times, Telegraph, Independent and Guardian discussing whether Brown would survive. Of those, half predicted he would go, while only a quarter thought he might stay (the rest, perhaps wisely, didn't chance their arm). If the broadsheet fortune-tellers could not assess the outcome of a backroom plot featuring a few ministers and MPs, how far should we trust their judgement on what tens of millions of voters will do?

This is probably unfair, and certainly unscientific. Brown did come close to being toppled last summer, and cabinet conspirators tend to duck out of ICM-style opinion polls. But, on the broad question of whether we should set much store by political predictions, the answer is a flat no.

Aditya also flags up a fascinating book by the University of California, Berkeley psychiatrist Phil Tetlock, based on his 20-year study of predictions by political, media and economic experts, which found that they are no better than the rest of us at prognostication.

As a Conservative MP, I want Parliament to get a proper debate on Brexit

The government should consider a Green Paper before Article 50. 

I am very pleased that the government has listened to the weight of opinion across the House of Commons – and the country – by agreeing to put its plan for Brexit before Parliament and the country for scrutiny before Article 50 is triggered. Such responsiveness will stand the government in good stead. A confrontation with Parliament, especially given the paeans to parliamentary sovereignty we heard from Leave campaigners during the referendum, would have done neither the Brexit process nor British democracy any good.

I support the government’s amendment to Labour’s motion, which commits the House to respecting the will of the British people expressed in the referendum campaign. I accept that result, and now I and other Conservatives who campaigned to Remain are focused on getting the best deal for Britain; a deal which respects the result of the referendum, while keeping Britain close to Europe and within the single market.

The government needs to bring a substantive plan before Parliament, which allows for a proper public and parliamentary debate. For this to happen, the plan provided must be detailed enough for MPs to have a view on its contents, and it must arrive in the House far enough in advance of Article 50 for us to have a proper debate. As five pro-European groups said yesterday, a Green Paper two months before Article 50 is invoked would be a sensible way of doing it. Or, in the words of David Davis just a few days before he was appointed to the Cabinet, a “pre-negotiation white paper” could be used to similar effect.

Clearly there are divisions, both between parties and between Leavers and Remainers, on what the Brexit deal should look like. But I, like other members of the Open Britain campaign and other pro-European Conservatives, have a number of priorities which I believe the government must prioritise in its negotiations.

On the economy, it is vital that the government strives to keep our country fully participating in the single market. Millions of jobs depend on the unfettered trade, free of both tariff and non-tariff barriers, we enjoy with the world’s biggest market. This is absolutely compatible with the result, as senior Leave campaigners such as Daniel Hannan assured voters before the referendum that Brexit would not threaten Britain’s place in the single market. The government must also undertake serious analysis on the consequences of leaving the customs union, and the worrying possibility that the UK could fall out of our participation in the EU’s Free Trade Agreements (FTAs) with non-EU countries like South Korea.

If agreeing a new trading relationship with Europe in just two years appears unachievable, the government must look closely into the possibility of agreeing a transitional arrangement first. Michel Barnier, the European Commission’s chief negotiator, has said this would be possible and the Prime Minister was positive about this idea at the recent CBI Conference. A suitable transitional arrangement would prevent the biggest threat to British business – that of a "cliff edge" that would slap costly tariffs and customs checks on British exports the day after we leave.

Our future close relationship with the EU of course goes beyond economics. We need unprecedentedly close co-operation between the UK and the EU on security and intelligence sharing; openness to talented people from Europe and the world; and continued cooperation on issues like the environment. This must all go hand-in-hand with delivering reforms to immigration that will make the system fairer, many of which can be seen in European countries as diverse as the Netherlands and Switzerland.

This is what I and others will be arguing for in the House of Commons, from now until the day Britain leaves the European Union. A Brexit deal that delivers the result of the referendum while keeping our country prosperous, secure, open and tolerant. I congratulate the government on their decision to involve the House in their plan for Brexit - and look forward to seeing the details.
