Is it proper to use the phrase "failed experiment" at all? And if so, should it refer exclusively to experiments that had some ineluctable flaw in the process of their implementation or can it also refer to experiments that achieved the undesired result?
This could have some bearing on the formality with which we interpret "experiment" as "scientific experiment", touched upon here, but my more basic question is the validity of calling something a "failed experiment": Does that imply that the act of experimenting was itself a failure or that it resulted in a failure. It would sound like the former, but I think the interpretation is often the latter.
