What correlation was found in the research reviewed in this article?
The author cautions that we should be careful not to jump to causal conclusions regarding this behavior because of possible third variables. Name one of the third variables the author identifies, and explain how it makes it difficult to draw a causal conclusion regarding drinking and sexual behavior.
The author also suggests that there might be a directionality problem in trying to draw a causal conclusion regarding drinking and risky sexual behavior. Use an example provided by the author to explain how concluding that the one variable causes the second variable to change may ignore the possibility that the second variable is actually influencing the first variable.
