Interpretation pitfall II: An empirical relationship does not imply causation

Interpretation pitfall II: An empirical relationship does not imply causation

(Health status report, 1994, Hungarian Central Statistical Office):

„smokers see their GP less frequently than non-smokers”

... and the explanation:

„for a smoker, who knows that smoking is unhealthy, seeing the GP may be an unpleasant situation.”

What do you think?

Use the background information below.

From the survey data:

Gender

Average annual frequency of seeing the GP

Frequency of smokers

Male

4.34

44%

Female

6.38

27%

Relationship between smoking and seeing the GP may be spurious. Gender itself may explain this relationship. How?
