How to escape from jail: a tough but intelligent approach

Martha Gill's Irrational Animal's Column.

As David Cameron’s approach to crime gets “tough but intelligent” (if he says so himself), now might be the time for the rest of us to take a tough but intelligent approach to staying out of prison. For it can be done – and not just through blameless living.

One fairly sure way is to appear before a jury right after lunch. It’s an old courtroom legend – that the outcome of a trial depends on what the judge ate for breakfast – but here's some evidence to back it up. A scientist called Shai Danziger collected the results of 1,112 hearings from prisons in Israel, plotting how often judges granted parole against how long it had been since they last ate. The results were remarkable. The odds of getting out of jail free start at about 65 per cent right after everyone’s had a sandwich and then fall off to almost zero after a couple of hours. Feed the judges another sandwich and their generosity climbs right back up again.

Human willpower, you see, is a finite resource. When judges resist the hunger pangs, they are dipping in to reserves of stamina, making tempers short and sentences long.

Take a look at this experiment, conducted by Baba Shiv at Stanford. It was constructed as an exercise in resisting temptation, in the form of a slice of chocolate cake. Subjects were asked to remember strings of numbers (not long strings, just two to seven digits). Resisting the cake was easy after two digits but became almost impossible after seven. It took just a couple of extra pieces of information to wear down the subject’s willpower completely. Willpower is that weak. Life only needs to batter you slightly and you will go for the harsher jail sentence, leave the washing-up for tomorrow, have another drink, nick a watch.

And when your willpower is worn down, you are more likely to make snap judgements based on stereotypes, becoming sexist and racist. And this is a problem for judges, because evidence shows they are already vulnerable to these sorts of influences. So, if you want to stay out of prison, try being female rather than male, white rather than black, baby-faced rather than mature-looking. If you are a psychopath, make sure your defence explains the biology behind this to the jury. A study recently written up in the journal Science showed that this reduces sentencing by an average of one year.

If you want to stay out of prison, it also helps to make your statement rhyme. This loophole in judgement is known as the “Keats heuristic”, in which beauty is mistaken for truth, rhyme for reason. Johnnie Cochran used it to get an acquittal for O J Simpson, with his signature phrase: “If it doesn’t fit, you must acquit.” Sounds right, doesn't it?

Wriggling out of a jail sentence or falling into one undeservedly has never been so easy. However, if, for symmetry, we were to take a tough but intelligent approach to jury standards, there are a couple of things we could do.

According to Birte Englich from the University of Cologne, making judges play games that teach them their own biases can help. Mandatory guidelines for sentences have been introduced in America (although they are being resisted) and there have been initiatives in New South Wales to increase the size of juries. Compulsory biscuit eating before each hearing can only be the next step.

Donald Trump's inauguration signals the start of a new and more unstable era

A century in which the world's hegemonic power was a rational actor is about to give way to a more terrifying reality. 

For close to a century, the United States of America has been the world’s paramount superpower, one motivated by, for good and for bad, a rational and predictable series of motivations around its interests and a commitment to a rules-based global order, albeit one caveated by an awareness of the limits of enforcing that against other world powers.

We are now entering a period in which the world’s paramount superpower is neither led by a rational or predictable actor, has no commitment to a rules-based order, and to an extent it has any guiding principle, they are those set forward in Donald Trump’s inaugural: “we will follow two simple rules: hire American and buy American”, “from this day forth, it’s going to be America first, only America first”.

That means that the jousting between Trump and China will only intensify now that he is in office.  The possibility not only of a trade war, but of a hot war, between the two should not be ruled out.

We also have another signal – if it were needed – that he intends to turn a blind eye to the actions of autocrats around the world.

What does that mean for Brexit? It confirms that those who greeted the news that an US-UK trade deal is a “priority” for the incoming administration, including Theresa May, who described Britain as “front of the queue” for a deal with Trump’s America, should prepare themselves for disappointment.

For Europe in general, it confirms what should already been apparent: the nations of Europe are going to have be much, much more self-reliant in terms of their own security. That increases Britain’s leverage as far as the Brexit talks are concerned, in that Britain’s outsized defence spending will allow it acquire goodwill and trade favours in exchange for its role protecting the European Union’s Eastern border.

That might allow May a better deal out of Brexit than she might have got under Hillary Clinton. But there’s a reason why Trump has increased Britain’s heft as far as security and defence are concerned: it’s because his presidency ushers in an era in which we are all much, much less secure.
