Wikipedia:Articles for deletion/Blinovitch Limitation Effect
The subject is discussed, with significant coverage, in reliable secondary sources (the cited books by Parkin, Letts and Miles).  The fact that the secondary sources are all related to ''Doctor Who'' is irrelevant; discussion of any fictional subject is most likely to be found in material focused on that subject.  The key is that these sources — all non-fiction, or at least containing significant non-fiction elements — discuss the idea in a real-world context beyond its role in the plots of specific ''Doctor Who'' stories.   lists three criteria for keeping articles with fictional subjects: real-world coverage, importance of the fictional work, and role within the fictional work.  I think this meets all these criteria
