The Shape of Code

The Nostradamus argument in software engineering research goes something like: This idea was proposed in a paper by XX, some years ago.

I regularly encounter the Nostradamus argument when discussing what people in industry are doing, with one or more academics. The same argument is probably made in other fields.

The rules of academic research pretty much guarantee that somebody, at sometime, has published a paper containing an idea related to something being discussed today.

The first researcher(s) to publish an idea gets the credit for the idea, and ‘uses it up’ the idea, that is somebody else cannot subsequently publish a paper claiming that idea (it does happen, either through plagiarism or slip-ups during review).

The job of researchers is to find new ideas (well, actually these days it is to quickly find an idea that will get published; researchers are on a publication treadmill). Sometimes a paper will explicitly point out the novel idea they are claiming (usually a sign of a very poor paper; the author(s) obviously don’t feel confident that the reader will see anything of merit). Researchers also talk of gaps in the literature, i.e., some topic where little, if anything, has been published.

Before starting work in an area, researchers are supposed to read all relevant prior publications; this can be an awful lot of work and take a lot of time. In practice people tend to read the papers in the top 10, or so, journals published in the last few years; maybe looking at more journals and going further back in time if the initial search fails to return many results. I have had many conversations with researchers about a paper, or thesis, they are just completing and been told “I’m just finishing off the literature search”, i.e., they are doing the background checks after completing their research, not before (yes, sometimes rather similar work has already been published and some quick footwork is needed).

So the work of prior researchers is venerated in theory, but rarely in practice.
