Title text: If you think this is too hard on literary criticism, read the Wikipedia article on deconstruction.
While the comic is ostensibly about grad students, it is really Randall's way of poking fun at different fields. Given that engineers can detect his BS quickly suggests he regards engineering with some respect. In other words, he thinks engineering has a low BS quotient. Similarly with linguists. He clearly thinks less of sociology, since his BS can go undetected for considerably longer. And the field of "Literary Criticism" is something he considers mostly, or entirely, BS, since he claims his BS has repeatedly been published.
The first panel shows Cueball discussing an engineering problem with Ponytail. Logarithms are a mathematical tool used for expressing an exponential relationship as a linear one. While this has many uses in a variety of fields, it is not a suitable tool for dissipating excess heat. (It might have value in plotting temperature change over time, or temperature over distance, however.)
Since Klingon is a constructed language designed to sound "alien" and which explicitly avoids sounding like any human language, it cannot be part of any real-world linguistic family. Any linguist who knows what a Klingon is would instantly recognize his statement as a joke, so the detection time should be only a few seconds. His assertion that his BS went undetected for over a minute suggests he does not expect linguists to be familiar with Star Trek.
The third panel is a bit more subtle. While sociology can certainly use ranking as an analytical tool, the trouble lies in the complete lack of meaning in the tags "best" and "worst". Detecting this as BS requires a bit more effort on the part of the sociology grad students.
Literary criticism, on the other hand, is almost completely written in buzz words and jargon, and is thus difficult for anyone, including those versed in the field, to understand. His assertion that he published 8 papers and 2 books could also be his way of saying that he doesn't believe anyone actually reads any of the stuff published in the field.
- My Hobby: Sitting down with grad students and timing how long it takes them to figure out that I'm not actually an expert in their field.
- Student: Our big problem is heat dissipation
- Cueball: Have you tried logarithms?
- 48 seconds
- Cueball: Ah, so does this Finno-ugric family include, say, Klingon?
- 63 Seconds
- Cueball: Yeah, my latest work is on ranking people from best to worst.
- 4 Minutes
- Literary Criticism:
- Cueball: You see, the deconstruction is inextricable from not only the text, but also the self.
- Eight papers and two books and they haven't caught on.
