I enjoy this in the sense with which it's published, but I feel like the authors overlooked one key meaning of the phrases "It's not rocket science" and "It's not brain surgery." They interpret both to mean, essentially, "It doesn't take a genius". That is a valid interpretation, but there is an additional meaning that they gloss over entirely.

Both fields require extensive specialized education, training, and experience. They study only looks at whether the people in these fields are more intelligent than the average population (and one another). In that sense, whether people in those professions score higher on a cognitive test is irrelevant.

Which is all to say, much like the authors of this paper, I am taking a trivial matter far too seriously and being nitpicky to no one's benefit.
