Wonga are blinding critics with science

The payday loan company shows off about its algorithm, but lends to the same vulnerable people.

I read Michael Brooks' article, Doing Science the Wonga Way, with great interest.

I have had the algorithm Wonga uses to distinguish between applicants explained to me, and it is fascinating. It makes the most of the fact that the internet is replete with thousands of pieces of information about us that, in aggregate, paint a reasonable picture of who we are. More importantly for Wonga, they also paint a picture of how creditworthy we might be. It doesn't take this lightly: I've been told it uses 6-8000 data points about the each of the people it checks.

The problem was that I only had the algorithm explained to me after its accuracy was seriously put in to question.

Wonga has a weekly survey of people who they consider to be good customers, and they brag about them to journalists. When the Guardian's Amelia Gentleman interviewed Errol Damelin, the chief executive of Wonga, he and his team had a chance to show that their model worked. When they put names of potential customers through their high-tech filters, the system ought to tell them whether they would be good customers. They would then only lend if it would be responsible to. After all, Wonga says that it turns away two-thirds of applicants.

Rather than the "web-savvy young professionals" that the company says that it lends to, one of the "good customers" on their weekly survey was Susan, an unemployed former nurse dependent on disability benefits. She uses the loans she receives from Wonga to buy food when she is short of cash. In fact, at the time of the Guardian interview, she had taken out 6 loans with Wonga, nearly double the amount of payday loans the average customer takes out (3.5).

We have two options here. Either we can assume Wonga purposefully targets people who are not median income, employed and web-savvy, unlike what they say, or their algorithm doesn't work as well as they say.

In the same interview with the Guardian, John Morwood, Wonga's communications director, said:

Sometimes we will make loans to people on significant benefits, but it is not something we do very frequently. It is very infrequent. I’m not going to say it doesn’t happen.

Dr Brooks is correct to say that the company has enjoyed some fantastic and enviable funding from several organisations. Last time I looked, Wonga were the beneficiaries of £3.7m from Balderton Capital in 2007, £14m from Accel Partners (also investors in Facebook) in 2009, then £73m from Oak Investment Partners, Meritech Partners and the Wellcome Trust.

I can't be certain, but my assumption is that at least some of these backers are interested in Wonga as an example of good science put into action by business, and aren't particularly interested in funding legal loansharking.

But Wonga's algorithm clearly doesn't alter the fundamentals of their business as much as they claim. Even with their flashy, investor-attracting scientific background, they still lend to people whose custom they admit they ought not to take.

Wonga itself is either misusing its own system to justify lending to people who should be served by less expensive lenders such as credit unions (which I think payday lenders should be obliged to advertise to low-income customers), or its algorithm needs a lot more work than it says.

As it stands, if the system confuses repeat borrowers who are unemployed and on benefits to buy food for people who are middle class, have bank accounts, are in full time employment and need the cash for minor financial shocks here and there, then there is a major issue.

It's easy to see where Berlin is being rebuilt – just hit the streets

My week, from walking the streets of Berlin to class snobbery and the right kind of gentrification.

Brick by brick, block by block, the people are rebuilding the city once called Faust’s Metropolis. To see it clearly, put your boots on. One of the most bracing walks starts by the Gethsemane Church, which served as a haven for dissenters in the last days of the GDR and takes you down ­towards the Hackescher Markt.

Here, in what is still the eastern half of a divided city that wears its division more lightly, is a Berlin experience both old and new. In three decades of frequent visits, it has been fascinating to note how much this part of town has changed. Even a decade ago these streets were rundown. With crumbling buildings showing bulletholes, it wasn’t hard to imagine what the place looked like in 1945. Now there are lilacs, blues, and yellows. Cafés, bars and restaurants abound, serving the young professionals attracted to the city by cheap rents and a renewed sense of community.

 

Breaking the fourth wall

Looking north along Schliemannstraße, you’ll find a delightful vista of well-tended balconies. It’s a pleasant place to live, notwithstanding the gaggle of grotesques who gather round the corner in the square. On Kastanienallee, which forms the second leg of the walk, an old city feels young. It’s a kind of gentrification but the right kind. There’s more to eat, to drink, to buy, for all.

Berlin, where Bertolt Brecht staged his unwatchable plays, was supposed to have been transformed by a proletarian revolution. Instead, it has been restored to health by a very middle-class one. Germany has always had a well-educated middle class, and the nation’s restoration would have impossible without such people. The irony is delicious – not that irony buttered many parsnips for “dirty Bertie”.

 

The new snobbery

The British Museum’s survey of German history “Memories of a Nation” is being presented at the Martin-Gropius-Bau as “The British View”. Germans, natürlich, are curious to see how we observe them. But how do they see us?

A German friend recently in England  said that the images that struck him most forcibly were the tins of food and cheap booze people piled up in supermarkets, and the number of teenage girls pushing prams. Perhaps Neil MacGregor, the former director of the British Museum who will shortly take up a similar role here at the new Humboldt Forum, may turn his attention to a “German View” of the United Kingdom.

There’s no shortage of material. In Schlawinchen, a bar that typifies Kreuzberg’s hobohemia, a college-educated English girl was trying to explain northern England to an American she had just met. Speaking in an ugly modern Mancunian voice that can only be acquired through years of practice (sugar pronounced as “sug-oar”), she refer­red to Durham and York as “middle class, you know, posh”, because those cities had magnificent cathedrals.

When it comes to inverted snobbery, no nation can match us. To be middle class in Germany is an indication of civic value. In modern England, it can mark you as a leper.

 

Culture vultures

The Humboldt Forum, taking shape by the banks of the Spree, reconsecrates the former site of the GDR’s Palace of the Republic. When it opens in 2018 it will be a “living exhibition”, dedicated to all the cultures of the world. Alexander von Humboldt, the naturalist and explorer, was the brother of Wilhelm, the diplomat and philosopher, whose name lives on in the nearby university.

In Potsdamerplatz there are plans to build a modern art museum, crammed in between the Neue Nationalgalerie and the Philharmonie, home to the Berlin Philharmonic. Meanwhile, the overhaul of the Deutsche Staatsoper, where Daniel Barenboim is music director for life, is likely to be completed, fingers crossed, next autumn.

Culture everywhere! Or perhaps that should be Kultur, which has a slightly different meaning in Germany. They take these things more seriously, and there is no hint of bogus populism. In London, plans for a new concert hall have been shelved. Sir Peter Hall’s words remain true: “England is a philistine country that loves the arts.”

 

European neighbours

When Germans speak of freedom, wrote A J P Taylor, a historian who seems to have fallen from favour, they mean the freedom to be German. No longer. When modern Germans speak of freedom, they observe it through the filter of the European Union.

But nation states are shaped by different forces. “We are educated to be obedient,” a Berlin friend who spent a year at an English school once told me. “You are educated to be independent.” To turn around Taylor’s dictum: when the English speak of freedom,
they mean the freedom to be English.

No matter what you may have heard, the Germans have always admired our independence of spirit. We shall, however, always see “Europe” in different ways. Europe, good: we can all agree on that. The European Union, not so good. It doesn’t mean we have to fall out, and the Germans are good friends to have.

 

Hook, line and sinker

There are fine walks to be had in the west, too. In Charlottenburg, the Kensington of Berlin, the mood is gentler, yet you can still feel the city humming. Here, there are some classic places to eat and drink – the Literaturhauscafé for breakfast and, for dinner, Marjellchen, a treasure trove of east Prussian forest delights. Anything that can be shot and put in a pot!

For a real Berlin experience, though, head at nightfall for Zwiebelfisch, the great tavern on Savignyplatz, and watch the trains glide by on the other side of Kantstraße. Hartmut Volmerhaus, a most amusing host, has been the guvnor here for more than 30 years and there are no signs that his race is run. The “Fisch” at twilight: there’s nowhere better to feel the pulse of this remarkable city.
