ddstretch: It is worth making the point that correlation does not imply causality, and people who might be tempted should not see anything other than a joke in the main comment or summary attached to this graph. (about 1 year ago)
: Older people drink more wine. Younger people commit more crime. The population is aging. (about 1 year ago)
: Moe's right. More disposable income leads to less crime and more buying spree's.. (about 1 year ago)
ddstretch: All the explanations have one thing in common: they say that the two dependent variables (wine drinking and violent crime) do not have a direct causal link with each other. Instead, they share a common cause, though the common cause is not the same across all explanations. If two variables have a common cause, then one does not cause the other. Most statistical textbooks dealing with these kinds of modeling issues will state this as an elementary claim. (about 1 year ago)
: I wonder if the "wine" in the study includes Maddog 20/20. Corked wine vs. Screw-top? Having said that, I have to agree with Matt. I have never heard of a gangster with a taste for the full bodied, robust, yet slightly tannic Burgundy wines. (about 1 year ago)
