Sure, in the case of a very small and new field with promise of intellectually stimulating work and structural advantages for eliminating bullshit, adding more people and papers is likely going to be a net benefit. But realistically many established disciplines can only add people by lowering standards.
What I understand as the central point of your original comment was that we cannot condemn all of the social sciences (or 90% of the work in them) on the basis of the Claudine Gay story. I refute that with this sentence:
>The longer such fraud goes uncorrected, the more rewarded a person is for their fraud, and indeed the more lengths other people go to cover up such fraud (as was argued by the OP) the more likely such fraud is normalized in a particular field. The Claudine Gay story suggests that, if anything, XKCD was wildly optimistic about the social sciences.
Put another way, in the spirit of Scott Alexander's recent essay "Against Learning From Dramatic Events", the Claudine Gay story represents a significant deviation from what would be predicted by a model that assumed the social sciences had a more robust level of intellectual integrity.
