Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. And ultimately predictive models should be used to the extent that they can assist our ultimate scientific goal of explaining mind and behavior. For example, study subjects might act differently if they know that they are being watched. Yet, while we are deep believers in the causal inference toolkit, weve also seen the reverse problem leaders who overlook useful patterns because they are not causal. Or, more specifically, the distinction between predicting an outcome and predicting how a decision will affect an outcome. Concurrent validity (correlation between a new measure and an established measure). A typical report of a correlation is based on one group of people, at one time, in one place.
