I'm not sure what to make of this. I think Hank is taking the idea that correlation is good enough too seriously. Since I've been playing with correlations at home and learning how people find correlations in huge data sets, I've found that a correlation actually is good enough for most purposes. Think about what the correlation is used for. It makes suggestions on things to buy or things you should explore. It's making suggestions. A movie suggestion is exactly that, a suggestion. It's not an exact science and you can't have a 100% guarantee that a consumer will be into something enough to buy it. It's the same thing as trying to predict the market. The correlations can provide a useful service for getting information to people about things they might like. Hopefully the service makes it easy to buy the product and then the picture seems complete.
