A lighthearted article in the New England Journal of Medicine noted that there is a strong relationship between the per capita consumption of chocolate in a given nation and the number of Nobel Prize winners produced by that nation. One conclusion readily presents itself: People who consume more chocolate are smarter, and therefore national populations that consume more chocolate produce more Nobel winners. But how else could this relationship be interpreted? Be precise, be skeptical, look at the evidence, and offer some alternative interpretations.
