Yea, “should be”, but as said, if it’s not literally directly relevant even while being in the paper, it might get skipped. Lazy? Sure. Still understandable.
A more apt coding analogy might be code reviewing unit tests. Why dig in to the unit tests if they’re passing and it seems to work already? Lazy? Yes. Though it happens far more than most non-anonymous devs would care to admit!
Some of the reviewers have explained it as the software they use doesn’t even load up the images. So unless the picture is a cited figure, it might not get reviewed directly.
I can kindof understand how something like this could happen. It’s like doing code reviews at work. Even if the logical bug is obvious once the code is running, it might still be very difficult to spot when simply reviewing the changed code.
We have definitely found some funny business that made it past two reviewers and the original worker, and nobody’s even using machine models to shortcut it! (even things far more visible than logical bugs)
Still, that only offers an explanation. It’s still an unacceptable thing.
