6.12.7 Identifying real correlations you don’t care about

In many cases, it is possible to identify two variables that are really correlated due to a confounder or some spurious relationship. A common example is the relationship between ice cream sales and murder in large cities. This correlation is real and reproducible across cities, but is due to the fact that high temperatures lead to both more murders and more ice cream sales. While this correlation is real, it isn’t one you care about. This is related to the problem of not reporting confounders.
