Going by LSAT scores, which provide a measure of critical reading skills, I don't see a strong trend by major. Math majors score highest [0]. Of course, this is a self selected sample.

I'd be curious to see evidence that STEM majors actually have worse critical reading skills. Or is it a subjective ranking you've derived?
