There’s a story told by a writer, trying working from home, who was so distracted by the noise from kids playing joyfully in the park by his house that he couldn’t concentrate. As a keen student of human nature, he decided to tell them that he loved their noise, and he would pay them each a dollar a day to keep it up. After a week, he told them he was reducing it to 50c; and shortly afterwards, he said he could no longer afford it, and they were free to keep going if they wished, but it would be for free. The kids drifted away, and the writer wrote in peace.
So what’s the best way of stopping children having fun? Pay them to do it, and then stop paying them. Make it a task to be completed to earn a reward; take away the joy.
There are lessons here for schools, which run on a similar combination of social psychology and economic theory. The equivalent question is What’s the best way to stop students learning? The answer is not so different.
But even leaving the moral argument aside, the evidence is that the carrots-and-sticks approach simply does not work to generate the behaviours we seek. As far as the stick part goes, the evidence in favour of non-punitive restorative justice over traditional punitive approaches is increasingly robust (see here and here for example) – but it’s on the carrots that I want to focus here.
Carrots – or rewards, incentives, call them what you will – are incredibly seductive. How could rewarding people for doing the right things be wrong? It seems so natural – indeed almost axiomatic to many. It even seems to be enshrined in the most fundamental economic ‘law’ – that raising (monetary incentives) increases supply and production. But the ‘laws’ of economics are far more complex than the ‘laws’ of physics, and far less universal. As a result, the narrow economic approach simply misses the point. In particular, it simply misses the subtlety of how choice works.
We want students and teachers to choose certain actions, and in doing so, choose to develop certain habits. And we want them to choose these actions even when no-one is looking; that is, we want the choices to be genuine ones. It turns out that the very act of reward can prevent this longer-term behaviour. The classic example comes from Titmuss (2000) who describes how many blood donors stop giving blood after the introduction of rewards for donations. It’s worth stopping and thinking here – because it says something fundamental. If you wanted to give blood for free, wouldn’t a bit of cash make it even more attractive?
It turns out not. It turns out that when otherwise wholly volitional behaviours come to be seen as something done for external reward, the original reason for doing them (in this case the intrinsic satisfaction of helping others) can be ‘crowded out’. Frey (2001) describes this same phenomenon in many disparate areas where carrots are used to incentivise behaviour, but have the perverse effect of decreasing it. From patients’ readiness to take prescribed medication to the reaction of managers to various forms of supervision by their superiors; to the readiness to offer voluntary work; even the readiness to accept nuclear waste repositories, the evidence is consistent. Most importantly for us in schools, Frey marshals empirical evidence that backs up what others (eg Kohn1993) have long said; that childrens’ learning behaviour is hindered, not supported by rewards.
The wrong tools are likely to damage the things we apply them to. |
I am referring to schools here, and I am convinced that neither carrots nor sticks do what we want them to do. Now, perhaps there are places where carrots-and-sticks may work. I am thinking of my time as a teenager stacking shelves in supermarkets. I was not motivated by anything other than the money; the work had no intrinsic motivation for me. I turned up, did the hours, took no real pride in the work and while I did it honestly, I did it to the absolute minimum requirements. Perhaps it would have made sense to pay me by the number of shelves I could get done, rather than by the hour (even there I have doubts; I suspect that offering me choice and the chance to work in a team would have been more motivating for me). So when the work is intrinsically unattractive and dull, and if we cannot find ways to make it interesting, perhaps we need carrots; and perhaps that’s the right model for motivation. Perhaps.
But this model for motivation gets carried far beyond it’s proper domain, to places where it really should not belong, because the work is not simple, and not short-term. Many conversations in schools – about ‘behaviours’, ‘assessment’, ‘discipline’, ‘awards’ and ‘performance-related-pay’, for example – are about this issue, sometimes buried deep in layers of assumptions. Perhaps the best single-line summary comes from Ryan and Deci’s authoritative overview: rewards may lead to improved performance on simple tasks but impair performance on more complex tasks.
It’s dangerous to extend a model of thinking beyond its useful domain. This is one of those times, and I am reminded of Maslow’s Law of the Instrument: When all you have is hammer, everything looks like a nail. It may sound harmless if we disguise our hammer as carrots and sticks – but it’s still a hammer, and people are not nails.
