»There is another questionable use of the word “standard” that is frequently encountered in the literature. After a complicated interactive problem P has been used in a couple of papers, subsequent papers refer to it as a standard problem. The casual reader is likely to think that something that is standard has withstood the test of time and that there’s a consensus among researchers that the assumption or problem is a reasonable one to rely upon—although neither conclusion is warranted in such cases. The terminology obfuscates the fact that the new problem is highly nonstandard.«
