If you click through to the study they are focused on a specific linguistic concept called dialog acts. Things that aren't part of dialog acts are not addressed in the study. You could take issue with that but it seems like a fairly rigorous approach that doesn't inherently dismiss other factors as being relevant. > If a cop walks up to a car with the engines still running, they're right to be wary. Are they? Do they handle this situation identically regardless of race? A thing you would need a study almost exactly like this one to find out.
