There is a misguided assumption in a lot of media reporting on research that correlation equals causation. Correlation is a statistical relationship between two variables – for example, amounts of social service funding and crime rates – that assumes that one variable has some degree of dependence on the other. In other words, if one variable changes, there should be a change in the other variable if the two are correlated.

In other words, I usually don’t spend a lot of time thinking about the implicit assumptions underlying the case.
So that’s why I was both excited and also somewhat embarrassed to see the results of a new study that (more…)
