Fourth Dimensional Critical Fanac

Satirical term coined by Terry Carr to describe how hyperfannish Trufans, by virtue of their fine, slannish high-type minds and their vast knowledge of all things fannish, past and present, can chart the course of fandom's future. Of course, thinking about publishing a fanzine or going to a club or convention or indeed anything about fandom at all would fall under the broad umbrella of Fourth Dimensional Mental Crifanac as well. Later, certain fans also spoke about Fourth Dimensional Verbal Crifanac –- which takes place any time two or more Trufen get together and give each other the benefit of their insight into the course of fandom's future.
