Why good forecasters become better people

Tim Harford in The FT

So, what’s going to happen next, eh? Hard to say: the future has a lotta ins, a lotta outs, a lotta what-have-yous. 

Perhaps I should be more willing to make bold forecasts. I see my peers forecasting all kinds of things with a confidence that only seems to add to their credibility. Bad forecasts are usually forgotten and you can milk a spectacular success for years. 

Yet forecasts are the junk food of political and economic analysis: tasty to consume but neither satisfying nor healthy in the long run. So why should they be any more wholesome to produce? The answer, it seems, is that those who habitually make forecasts may turn into better people. That is the conclusion suggested by a research paper from three psychologists, Barbara Mellers, Philip Tetlock and Hal Arkes. 

Prof Tetlock won attention for his 2005 book Expert Political Judgment, which used the simple method of asking a few hundred experts to make specific, time-limited forecasts such as “Will Italy’s government debt/GDP ratio be between 70 and 90 per cent in December 1998?” or “Will Saddam Hussein be the president of Iraq on Dec 31 2002?” 

It is only a modest oversimplification to summarise Prof Tetlock’s results using the late William Goldman’s aphorism: nobody knows anything

Yet Profs Mellers, Tetlock and Don Moore then ran a larger forecasting tournament and discovered that a small number of people seem to be able to forecast better than the rest of us. These so-called superforecasters are not necessarily subject-matter experts, but they tend to be proactively open-minded, always looking for contrary evidence or opinions. 

There are certain mental virtues, then, that make people better forecasters. The new research turns the question around: might trying to become a better forecaster strengthen such mental virtues? In particular, might it make us less polarised in our political views? 

Of course there is nothing particularly virtuous about many of the forecasts we make, which are often pure bluff, attention-seeking or cheerleading. “We are going to make America so great again” (Donald Trump, February 2016); “There will be no downside to Brexit, only a considerable upside” ( David Davis, October 2016); “If this exit poll is right . . . I will publicly eat my hat” (Paddy Ashdown, May 2015). These may all be statements about the future, but it seems reasonable to say that they were never really intended as forecasts. 

A forecasting tournament, on the other hand, rewards a good-faith effort at getting the answer right. A serious forecaster will soon be confronted by the gaps in his or her knowledge. In 2002, psychologists Leonid Rozenblit and Frank Keil coined the phrase “the illusion of explanatory depth”. If you ask people to explain how a flush lavatory actually works (or a helicopter, or a sewing machine) they will quickly find it is hard to explain beyond hand-waving. Most parents discover this when faced by questions from curious children. 

Yet subsequent work has shown that asking people to explain how the US Affordable Care Act or the European Single Market work prompts some humility and, with it, political moderation. It seems plausible that thoughtful forecasting has a similar effect. 

Good forecasters are obliged to consider different scenarios. Few prospects in a forecasting tournament are certainties. A forecaster may believe that parliament is likely to reject the deal the UK has negotiated with the EU, but he or she must seriously evaluate the alternative. Under which circumstances might parliament accept the deal instead? Again, pondering alternative scenarios and viewpoints has been shown to reduce our natural overconfidence. 

My own experience with scenario planning — a very different type of futurology than a forecasting tournament — suggests another benefit of exploring the future. If the issue at hand is contentious, it can feel safer and less confrontational to talk about future possibilities than to argue about the present. 

It may not be so surprising, then, that Profs Mellers, Tetlock and Arkes found that forecasting reduces political polarisation. They recruited people to participate in a multi-month forecasting tournament, then randomly assigned some to the tournament and some to a non-forecasting control group. (A sample question: “Will President Trump announce that the US will pull out of the Trans-Pacific Partnership during the first 100 days of his administration?”) 

At the end of the experiment, the forecasters had moderated their views on a variety of policy domains. They also tempered their inclination to presume the opposite side was packed with extremists. Forecasting, it seems, is an antidote to political tribalism. 

Of course, centrism is not always a virtue and, if forecasting tournaments are a cure for tribalism, then they are a course of treatment that lasts months. Yet the research is a reminder that not all forecasters are blowhards and bluffers. Thinking seriously about the future requires keeping an open mind, understanding what you don’t know, and seeing things as others see them. If the end result is a good forecast, perhaps we should see that as the icing on the cake.

Business schools help create a culture where the profit justifies the means

Business students learn accounting techniques, but not ethical decision-making. This is why corporate scandals persist writes Berend van der Kolk in The Guardian

As a university teacher of accounting, I see the world through a particular lens. When I read about the sales scandal at Wells Fargo, I can’t help but think about the people who naively designed the incentive schemes that triggered this type of unethical behaviour. When I hear about the complex transfer pricing schemes at companies such as Amazon and Starbucks that enable them to avoid tax, I start wondering which accounting techniques they used. In short, I see the strong connection between unethical business practices and accounting techniques.

One reason why these problems persist is that the textbooks used in most elementary management accounting courses ignore this connection. They tend to focus on the technical aspects of accounting – understanding the formulas, definitions, mechanics and calculations – while ignoring its ethical aspects. The ethical dimension is usually nothing more than an add-on in an isolated chapter, introduction paragraph, or in a separate course on business ethics. This makes ethics an afterthought detached from the topics it is intended to reflect on.

Take the example of transfer pricing – the practice of setting a price for a good or service delivered by one part of an organisation to another. When these units are located in different tax regions, the chosen transfer price affects the amount of tax that has to be paid. Various accounting textbooks discuss the technical aspects of transfer pricing, framed with questions such as “how can multinationals minimise their taxes payable?”. The ethics of whether it’s fair to avoid paying taxes – like how many developing companies are harmed by tax-avoiding multinationals - are rarely discussed.

This may lead students to believe that business decisions are only technical, and bear no ethical implications. In fact, business decisions almost always bear ethical implications: they may deteriorate work conditions elsewhere in the supply chain, create a profit-justifies-the-means culture or increase inequality on a global level.

We need to see a much stronger integration of ethical considerations into business education. This is how managers make real-life business decisions. This could be achieved through a discussion on the techniques and ethics of transfer pricing in one and the same accounting class, using a case that highlights both aspects. Business education should also challenge its own underlying assumptions about human behaviour, and bring in other disciplines such as the humanities to help students think critically about business practices that are taken for granted.

Of course it’s important that business students acquire technical skills, and universities shouldn’t be paternalising students by dictating what is and isn’t ethical. Instead, a more critical and integrated debate about the moral implications of financial instruments, accounting techniques and new technologies should play a central role in business education.

In the film Jurassic Park, Dr Ian Malcolm says: “Scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.” I would like us – business educators, but also students, managers and accountants – to not make that same mistake. Let’s take that step back every once in a while to reflect on the ethics of the technics.

The Craft of Writing Effectively

In Britain’s boardrooms, Brexit is already here. And the warning is stark

For Westminster, leaving Europe is months away: for business, it’s the present. And our prospects are already dwindling writes Aditya Chakrabortty in The Guardian

On the one hand, you have the self-inflating chaos at Westminster, the fever dreams of Jacob Rees-Mogg’s gang and the rehearsed rage of the Democratic Unionists. And on the other, you have the truth nailed by Philip K Dick. “Reality,” he wrote, “is that which, when you stop believing it, doesn’t go away.” So let’s remind ourselves of some reality.

While Tory MPs jostled over a replacement for Theresa May the head of the Confederation of British Industry, Carolyn Fairbairn, warned that millions of pounds were “flooding out” of business investment and into preparing for Britain crashing out of Europe with no deal. Food warehouses said they were running out of space. And auto-parts manufacturer Schaeffler announced that it would shut factories in Plymouth and Llanelli, leaving more than 600 workers facing the dole.


An entire rotten political-corporate regime is crumbling away – and its replacement threatens to be even worse

Even as politicians and the press fantasise about how Britain will leave Europe, big business is already at the departure gate. For Westminster, Brexit is months in the future; for boardrooms making plans, it is the present. Big carmakers have this year halved their investment in new models and factory machinery. The consultancy EY records a 31% slump in the number of foreign businesses setting up headquarters in Britain. Boris Johnson certainly makes good copy – but money talks much louder.

“The banks and insurers are moving, the big pharmaceutical firms are investing abroad,” says Paul Drechsler, who was CBI president until June and now chairs London First. “These trains are leaving the station, and when they leave, they won’t come back.” The country he describes is already shrinking, its job opportunities dwindling, its reputation abroad in eclipse.

This is the real national emergency. An entire rotten political-corporate regime is crumbling away – and its replacement threatens to be even worse. It will be worse, specifically, for those parts of the country, like Llanelli and Plymouth, that voted leave as the ultimate kick against the pricks of a hollow economy and a deaf government.

The succinct definition of our current model comes from the head of the Bank of England. The UK relies, said Mark Carney in 2016, on the “kindness of strangers”. The willingness of overseas investors to keep ploughing in their cash keeps us in the style to which we’ve grown accustomed. Out of all the 28 members of the European Union, the UK is second only to Ireland in its dependence on investment from abroad. Margaret Thatcher’s eagerness to sell off whatever she could get her hands on and her mandarins’ carelessness over ownership has turned us into one of the biggest foreign-capital junkies in the developed world. 

Those investors don’t come here out of charity. Our government competes with others around the world to lure in cash from overseas. But look what inducements we offer. Just weeks before the Brexit referendum, David Cameron’s government published its Invest in the UK brochure, promising “the most competitive” labour costs in western Europe, and “the least strict regulation in the EU.”. Why buy euros when you can have Poundland?

No other country does this. Analysis by Kevin Farnsworth at York University shows that, while all states assure investors they’re competitive locations, Sweden boasts of its “anti-corruption” and “good industrial relations”, while Germany highlights its “efficiency” and “training”. The UK, he writes, “uniquely competes for international capital by offering a package of a low-tax, low-cost, low regulatory business environment”.

Here, whether Conservative or Labour, successive governments have marketed us as the open-all-hours, bargain-basement landing strip off mainland Europe. Until, that is, Britons vote in a referendum to kick away two of the three legs of the post-Thatcherite economic model, namely openness and closeness to the continent. What’s left then is our cheapness – in taxes, in wages and in regulation.

This is Britain in 2018, paying the price for decades of underinvestment and cutprice competition. We have a highly skilled workforce, with almost half of Britain’s young people holding a university degree. And yet in 2014, Charlie Mayfield, former boss of John Lewis and then head of the UK Commission on Employment and Skills, pointed out that over one in five British jobs required only primary-school education. We have a world-class car-manufacturing industry, yet over half of the components in the cars that roll off the lines in Sunderland or Ellesmere Port come from abroad.

This is the point at which the kindness of strangers starts to get rather strained. In a survey this spring, well before the chaos of the past few weeks, EY found that 30% of foreign investors now expect to move money out of the UK after Brexit. The current value of foreign direct investment in the UK is estimated by the government to be over £1 trillion. If even a quarter of that were to move abroad, then £75 billion of assets are already at risk. No wonder the Welsh government is offering sweeteners to Ford to stay at Bridgend. No wonder when Nissan made noises about scaling back at Sunderland, May immediately opened the door of No 10 and offered some kind of deal – although precisely what, the voting public was never told.

You can expect a lot more of this over coming months and years: panicky politicians paying your tax money to grumpy-looking corporate executives. You can expect other countries to try to poach our businesses, just as after the 2016 vote Paris began advertising itself as the ideal post-Brexit corporate headquarters. Their posters read: “Tired of fog? Try the frogs”

You can also expect this government to press even harder the case that Britain is the low-tax, low-wage capital of the rich world. But ministers will get a disappointing response from businesses, believes EY’s chief economist in the UK, Mark Gregory. He thinks multinationals will shift away from using Britain as a stepping stone into Europe and the rest of the world – which is logical, given that any new trading arrangements will take years to settle and will almost certainly not be as smooth as the regime Britain currently has. Instead of building factories to make things to sell to the world, big businesses will instead put their money into storage and showrooms to sell things to Britons. The UK will become, Gregory says, “a warehouse economy: low skills, low productivity and low growth”.

That projection was already a reality for lots of people I met who plumped for Brexit in 2016. They were on minimum wage and had minimum rights and minimum prospects. If Brexit is to be radically changed now, it is those voters – the disenfranchised Labourites, the sod-them-all brigade – whose support is needed. A second referendum, in which well-meaning metropolitans offer those in the Rhondda the status quo, probably deserves to fail. Instead, any remain option will have to come with a worked-out argument about rebalancing power in this country. And that means reshaping the relationship between capital and the rest of us.

Why did Andrew Marr lose it with Shami Chakrabarti?

The establishment is throwing its toys out of the pram, with old-guard political broadcasters struggling to cope with change writes Faiza Shaheen in The Guardian 


BBC viewers used to the genteel, unflappable Andrew Marr might have had a shock on Sunday morning when the veteran broadcaster suddenly snapped. His guest, Shami Chakrabarti, explaining how Labour would follow through the Brexit referendum result, said: “I don’t know about you, Andrew, but I’m a democrat.” To which he barked, jabbing his crib notes in her face: “Don’t try and patronise me – I’m as much a democrat as you are!”

Change is hard to deal with – especially, it seems, for old-guard political broadcasters. Right now the number of women and people of colour coming forward and challenging the establishment is growing and the establishment is not taking it at all well. Yes, we can read their behaviour as bullying and obviously unacceptable, but Marr’s retort to Chakrabarti is just another sign that they have their knickers in a twist.

As well as Marr’s aggression, in recent weeks we’ve had Andrew Neil tweeting an outrageous insult about the award-winning journalist Carole Cadwalladr, Adam Boulton retweeting people who chastise me for sounding like I’m from east London, and Piers Morgan telling people of colour they should leave the country if they don’t take more pride in Britain.

The more I find myself in prestigious TV green rooms, traditionally not the spaces for women of colour from a working-class background, the more I see how establishment biases play out both on and off screen.

The first time I went on the Andrew Marr Show I was struck by the “in-crowd” cosiness of it all. In the green room the guests’ conversation consisted of showing off about who’d most recently had dinner with David Davis. On another occasion a Tory grandee completely ignored me. He said hello and goodbye to everyone else (all older, middle-class and white) on the panel and just looked straight past me as if I were invisible. This was particularly weird given that I directly addressed him while we were on air.


It’s no coincidence that before before last year’s election Diane Abbott, a black woman, received more online hate than any other politician

Sometimes the bias is more subtle. The organisation I run, Class, is often introduced on air as a leftwing or trade-union-supported thinktank. This doesn’t bother me – we’re transparent about where we get our money from and our political stance. However, it does irk me that my counterparts on the right are almost never introduced with their political bias upfront – and they are rarely transparent about where their funding comes from, which means that their vested interests are never called out.

And let’s consider why Marr might have had so much latent anger towards Chakrabarti: could it be that he no longer understands the world around him? He probably never imagined the rise of Jeremy Corbyn, whose shadow cabinet includes more working-class people, women and ethnic minorities than any before.

We cannot let the media dinosaurs – people who should be taking a long hard look at their prejudices – make us feel we’re the ones in the wrong. And this has real-world consequences: it’s no coincidence that before last year’s election Diane Abbott, a black woman, received more online hate than any other politician.

Nowadays I’ve taken to drawing satisfaction when seeing outbursts such as Marr’s: it’s the privileged white-male equivalent of throwing toys out of the pram, and shouting: “It isn’t fair!” We need to fight their attitudes and demand fairer representation, but we should also take pride in the fact that they’re finally being forced to acknowledge us.

When a woman sought justice on harassment, the Lords closed ranks

Jasvinder Sanghera has spent her life fighting sexual abuse. But the upper house has shielded Lord Lester from punishment writes Kate Maltby in The Guardian

 
Jasvinder Sanghera: “How can I suggest that victims of sexual harassment and bullying should complain to the Lords? I don’t want them to go through what I’ve been through.”


When the #MeToo movement hit Westminster last year, some didn’t see what all the fuss was about. Those of us who had put our names to complaints of sexual harassment were presented as over-privileged women operating in elite institutions: if we were miffed by the odd indecent proposal, or the occasional lunge from a politician, perhaps we needed an education in real suffering. 

No one can similarly accuse Jasvinder Sanghera of being sheltered when it comes to sexual violence. At 14 she ran away from home to escape a forced marriage, sleeping rough at first. Her sister Robina was less lucky. At the age of 24, Robina fatally set herself on fire after being told the family would disown her if she walked out on her husband’s physical violence. Since her sister’s death, Sanghera has spent 25 years campaigning against sexual abuse in traditional communities. Her charity, Karma Nirvana, helped make forced marriage overseas a criminal offence.

Last week, Sanghera outed herself as the woman who had made a complaint of sexual harassment against the Lib Dem peer Lord Lester. She would have felt like a “phoney”, she says, if she had continued campaigning against sexual violence in the family while allegedly tolerating harassment in the workplace.

Sanghera claimed that, while lending his support to her work, Lester had groped and harassed her and eventually promised: “If you sleep with me I will make you a baroness within a year”. He allegedly threatened to retaliate when she refused. Lester strongly denies all the allegations, though an investigation by the Lords’ commissioner for standards found against him. That investigation has since been scrutinised by two committee reviews, both of which again found against Lester. Overall, two law lords, two former lord chancellors, the former chair of the Equality and Human Rights Commission and 15 other peers have examined the case and ruled in Sanghera’s favour. But according to Lester’s friends in the House of Lords, this isn’t good enough.

As soon as the last appeal failed, Lord Pannick, a respected QC who is a close friend and supporter of Lester’s, launched a media campaign to discredit the investigation process in which he had just participated – including making the astonishing claim that Lester should have been allowed personally to cross-examine a woman who had accused him of sexual assault. Pannick’s campaign against Sanghera’s credibility read like a textbook case of establishment mobilisation: a column in the Times, where he is a regular columnist, and an appearance on the Today programme, where he called Sanghera “vague and contradictory”. There are, he alleges, errors or discrepancies in her memory. No doubt there are, at a distance of 12 years. But crucially, six witnesses gave evidence that Sanghera had confided in them about the alleged harassment at the time.

In his newspaper column and on the radio, Pannick drew our attention to a friendly note that Sanghera had inscribed to Lester in a copy of her book, after the key incident. Yet on neither occasion did Pannick acknowledge that Sanghera had been heavily questioned by the commissioner on this point, as she had been on every “challenge” made by Lester’s team. Sanghera’s side of the story is that Lester had requested the inscription at a large public setting “at the front of the queue of around 100 people”. She was still reliant on Lester’s help for her policy campaigns. She repeatedly told friends at the time that she still felt uncomfortable. But from Pannick’s media interventions, you’d be forgiven for thinking this was a smoking gun that had never been put to Sanghera in the investigation.

It is profoundly depressing that after a year of public discussion about sexual harassment, educated men still claim not to understand the pressure women feel to show harassers that there are no “hard feelings” . A female barrister at Pannick’s own chambers had the guts to point this out on Twitter, writing last week that: “I was sexually harassed by a Crown Court judge whom I spent a week work shadowing. At the end of the week I not only thanked him profusely for the opportunity, I actually sent him a Fortnums hamper to show my appreciation. Such is female socialisation in the 21st Century.” Harvey Weinstein’s victims were famously photographed grinning with him at parties.

The #MeToo movement has often been accused of disrespecting due process. Yet last week we saw a woman vindicated by an established process, and still denied justice when the Lords refused to pass a sanction against Lester on the grounds that it doubted the results of its own process.
Peer after peer turned up in the Lords on Thursday to swear that they had known Lester for donkey’s years and that he wouldn’t harm a fly. In court, an admission of lifelong friendship with the accused would immediately lead a juror or adjudicator to be recused from the case. Only in the House of Lords, it seems, does being a mate of the man in the dock particularly qualify a chap to try his case.

Many in the Lords were concerned that this case had been tried “on the balance of probabilities”, instead of “beyond reasonable doubt”. But the former is the civil law standard used in any employment tribunal: Lester was facing suspension from a job, not a jail sentence. In rejecting that standard of proof, the Lords has shown that it expects to be held to lower professional standards than any other place of employment. This cannot be right. If the Lords feels its own procedures are not fit for purpose, it must accept that modernisation is likely to be tougher, not easier on it. The Lords should be careful what it wishes for.
