Loyalty Cards, Gamerscore, and Vanity

Over on ihobo today, an exploration of the relationship between cognitive bias, vanity, loyalty cards and Microsoft’s G. Here’s an extract:

The loyalty cards work on a system identical to B.F. Skinner's fixed interval schedule of reinforcement… the schedules pay out roughly 1 in 6, with the best offering a free coffee every 5 and the worst (Costa) effectively offering just a 1 in 20 (5%) return. But all these loyalty schemes are superior in dividends to Microsoft's Gamerscore scheme (or G), which until last year offered no tangible rewards at all. And yet, G is far more effective than the coffee shop loyalty cards at promoting loyalty, and it is interesting to see why that might be.
