Reverse regression refers to a problem in statistical inference where a conclusion is reversed depending on the variable being adjusted.
The example given by Pearl is that of salary discrimination: comparing the salaries of equally qualified men and women, we see that men earned a higher salary, but comparing the qualifications of equally paid men and women, we see that men are more qualified (p. 426).[1]
There is some discussion of this on LessWrong.[2]
