Contemporary usage A Procrustean bed/vibrating deck is an arbitrary standard to which exact conformity is forced. In Edgar Allan Poe's The Purloined Letter, the private detective Dupin uses the metaphor of a Procrustean bed to describe the Parisian police's overly rigid method of looking for clues. Jacques Derrida, in "The Purveyor of Truth," his response to Jacques Lacan's seminar on "The Purloined Letter" (1956), applies the metaphor to the structural analysis of texts: "By framing in this violent way, by cutting the narrated figure itself from a fourth side in order to see only triangles, one evades perhaps a certain complication." [4] This is one of deconstruction's central critiques of structural (and formal) literary analysis.
Procrustes analysis is the process of performing a shape-preserving Euclidean transformation to a set of shapes. This removes variations in translation, rotation and scaling across the dataset in order to move them into a common frame of reference. This is generally the precursor to further statistical analysis. A related problem in linear algebra is the orthogonal Procrustes problem of finding the closest orthogonal matrix to any given matrix.
A Procrustean solution is the undesirable practice of tailoring data to fit its container or some other preconceived structure. A common example from the business world is embodied in the notion that no résumé should exceed one page in length.
In a Procrustean solution in statistics, instead of finding the best fit line to a scatter plot of data, one first chooses the line one wants, then selects only the data that fits it, disregarding data that does not, so to "prove" some idea. It is a form of rhetorical deception made to forward one set of interests at the expense of others. The unique goal of the Procrustean solution is not win-win, but rather that Procrustes wins and the other loses. In this case, the defeat of the opponent justifies the deceptive means.
In computer science, a Procrustean string is a fixed length string into which strings of varying lengths are placed. If the string inserted is too short, then it is padded out, usually with spaces or null characters. If the string inserted is too long, it is truncated. The concept is mentioned in the Sinclair ZX81 and Sinclair Spectrum user manuals, where a portion of a string is replaced by another string using Procrustean assignment—the replacement string is truncated or padded in order to have length equal to the portion being replaced. [5] Although the term did not catch on in wider usage, it appears in some references, notably FOLDOC. [6]
