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.

By refusing to stand down, Jeremy Corbyn has betrayed the British working classes

The most successful Labour politicians of the last decades brought to politics not only a burning desire to improve the lot of the working classes but also an understanding of how free market economies work.

Jeremy Corbyn has defended his refusal to resign the leadership of the Labour Party on the grounds that to do so would be betraying all his supporters in the country at large. But by staying on as leader of the party and hence dooming it to heavy defeat in the next general election he would be betraying the interests of the working classes this country. More years of Tory rule means more years of austerity, further cuts in public services, and perpetuation of the gross inequality of incomes. The former Chief Secretary to the Treasury, Seema Malhotra, made the same point when she told Newsnight that “We have an unelectable leader, and if we lose elections then the price of our failure is paid by the working people of this country and their families who do not have a government to stand up for them.”

Of course, in different ways, many leading figures in the Labour movement, particularly in the trade unions, have betrayed the interests of the working classes for several decades. For example, in contrast with their union counterparts in the Scandinavian countries who pressurised governments to help move workers out of declining industries into expanding sectors of the economy, many British trade union leaders adopted the opposite policy. More generally, the trade unions have played a big part in the election of Labour party leaders, like Corbyn, who were unlikely to win a parliamentary election, thereby perpetuating the rule of Tory governments dedicated to promoting the interests of the richer sections of society.

And worse still, even in opposition Corbyn failed to protect the interests of the working classes. He did this by his abysmal failure to understand the significance of Tory economic policies. For example, when the Chancellor of the Exchequer had finished presenting the last budget, in which taxes were reduced for the rich at the expense of public services that benefit everybody, especially the poor, the best John McConnell could do – presumably in agreement with Corbyn – was to stand up and mock the Chancellor for having failed to fulfill his party’s old promise to balance the budget by this year! Obviously neither he nor Corbyn understood that had the government done so the effects on working class standards of living would have been even worse. Neither of them seems to have learnt that the object of fiscal policy is to balance the economy, not the budget.

Instead, they have gone along with Tory myth about the importance of not leaving future generations with the burden of debt. They have never asked “To whom would future generations owe this debt?” To their dead ancestors? To Martians? When Cameron and his accomplices banged on about how important it was to cut public expenditures because the average household in Britain owed about £3,000, they never pointed out that this meant that the average household in Britain was a creditor to the tune of about the same amount (after allowing for net overseas lending). Instead they went along with all this balanced budget nonsense. They did not understand that balancing the budget was just the excuse needed to justify the prime objective of the Tory Party, namely to reduce public expenditures in order to be able to reduce taxes on the rich. For Corbyn and his allies to go along with an overriding objective of balancing the budget is breathtaking economic illiteracy. And the working classes have paid the price.

One left-wing member of the panel on Question Time last week complained that the interests of the working classes were ignored by “the elite”. But it is members of the elite who have been most successful in promoting the interests of the working classes. The most successful pro-working class governments since the war have all been led mainly by politicians who would be castigated for being part of the elite, such as Clement Atlee, Harold Wilson, Tony Crosland, Barbara Castle, Richard Crossman, Roy Jenkins, Denis Healey, Tony Blair, and many others too numerous to list. They brought to politics not only a burning desire to improve the lot of the working classes (from which some of them, like me, had emerged) and reduce inequality in society but also an understanding of how free market economies work and how to deal with its deficiencies. This happens to be more effective than ignorant rhetoric that can only stroke the egos and satisfy the vanity of demagogues

People of stature like those I have singled out above seem to be much more rare in politics these days. But there is surely no need to go to other extreme and persist with leaders like Jeremy Corbyn, a certain election loser, however pure his motives and principled his ambitions.
