Signaling And Selection
As I have discussed before there seems a lot to learn about social interactions, and that includes markets, from biology. Scientists in that area have long thought about problems that concern markets. For example, how can selection work to change a population?

The Danger of Data Mining
Is data analysis leading to bigotry? It is a sensitive subject. Data enthusiasts (and I’d probably be in this camp) hope analysis can get rid of silly ideas. After all when we get better information we will be able to combat old prejudices. I am genuinely optimistic. Still there is a major problem where your…
