Why Downing Street psychologists lied to jobseekers

Nudge Unit may have been trying to use the power of stereotypes and framing to help people get jobs - but that doesn’t mean it was a good idea.

Jobcentres have been foisting a bogus 'personality test' on the unemployed at the behest of Downing Street, bloggers uncovered earlier this week. The tests spat out random 'personal strength'’ to jobseekers who were forced to take part; traits like 'originality' and 'love of learning' – with the feedback apparently having no bearing on the responses people gave.

The ‘My Strengths’ test came from the much-hyped No.10 'Nudge Unit' (officially the Downing Street Behavioural Insight Team), which tries to use discoveries from the behavioural sciences to improve various parts of government. Why would they give the unemployed fake personality test?

One possibility that’s been floated is that they’re pseudoscientific snake oil salesmen with no idea what they’re doing. This is entirely possible. Equally likely, the problems with the seemingly pointless test could also be down to an IT screw-up – it wouldn’t be the first time.

But there is one explanation that I can think of that does make some sense. It’s possible Nudge Unit was trying to use the power of stereotypes and framing to help people get jobs.

There’s quite a lot of evidence to suggest that people 'play up' to stereotypes they have imposed on them. The most famous related experiment is the Stanford Prison Experiment: a random group of subjects are taken and divided into guards and prisoners, then made to staff a pretend prison. After a few days, both groups, picked at random, internalise their roles and the guards are lording it over the prisoners – people play up to the roles you give them.

One piece of research from the University of Canterbury on gender stereotypes illustrates what Nudge Unit's thinking might have been. A group of participants were asked by the Canterbury researchers to do mental arithmetic, and were paid according to the number of questions they got right. They could choose to be paid in one of two ways: either proportionally, according to the number of questions they got right, or in competition with others. The second option would lead to higher pay offs for those successful but with more risk of being left with nothing.

The twist is that before choosing between the two pay approaches, the subjects were given one of two questionnaires. Half were given a questionnaire about their career, the other half one about gender and family issues.

The results are interesting: In the group given the career questionnaire, men and women were equally likely to choose the competitive approach – 25 per cent of each. But given the questionnaire which highlighted gender issues, there was a big gender gap: 37 per cent of men went for the high-risk approach, and only 7 per cent of women.

One plausible conclusion from these results is that even something like a questionnaire is enough to ‘prime’ people’s decision-making and get them to play up to a stereotype. So it’s not inconceivable that Nudge Unit thought that a ‘personality test’ exercise that emphasised personal strengths could have a positive effect on an unemployed person who believed themselves to be unemployable. Their plan was probably to get people to internalise the strengths given to them in the questionnaire and to play that role as someone with a ‘love of learning’ or ‘perseverance’, or whatever made-up strength they decided they want jobseekers to think they have.

So there’s a bit of evidence behind this, and the fake tests might not be entirely cranky – but that doesn’t mean it was a good idea. It still involved the government wilfully lying to people, which most people would probably think was pretty unethical. Less 'nudging' than 'making things up'. And giving people an inaccurate picture of their strengths probably isn’t very healthy anyway – overconfidence is just as much of a problem as under-confidence; both are people not understanding their capabilities and lead to bad choices. One doesn’t necessarily compensate for the other.

Then there’s the fact that Nudge Unit seem to have quite ham-fistedly tried to take a laboratory finding and apply it to the real world without much skill. The questionnaire in the gender experiment 'primed' women to act less or more like their gender stereotype in the actions they were about to take, by changing the framing and context in which imminent decisions were made. But there’s no evidence it somehow permanently stripped them of their gender identity or made them think in more gender neutral terms for anything except the thing they were about to do. Unless the Jobcentre test was given to unemployed people directly before a job interview (it wasn’t) it’s difficult to see what the point would be, as it would be unlikely to have any long-term effect.

The transition from the laboratory to the field also failed in that by choosing to use fake tests, the initiative was set up to implode. It was only a matter of time before people figured out the tests were crap, and once it was common knowledge that they weren’t credible they’d look very silly and any benefits would disappear. This might not have been a factor in a controlled environment, but it is when you go out in the real world.

But worst of all, the whole approach of going to work on jobseekers’ egos is very arguably complete rubbish. It treats unemployment like an individual failing to be fixed at a personal level, rather than a problem of arithmetic where there are fewer jobs than the number of people who want them. This approach cannot work as a strategy to bring down unemployment: if this survey ever did somehow boost someone’s self-image and land them work, someone else who would have otherwise got the job would just lose out instead. The idea that we could fix unemployment if only we would just believe in ourselves is a dangerous fantasy, and to be fair to Nudge Unit, it’s not one exclusive to them.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
