Though the cartoon is primarily gentle ridicule of the natural sciences, some of the topics are applicable to the social sciences as well: My colleague is wrong and I can finally prove it; Some thoughts on how everyone else is bad at research.

The xkcd cartoon immediately set off an avalanche of variants in various specific fields, including at least two in areas of linguistics: Indo-European studies and syntax.
