“Ninety percent of everything is crud”. Derived from a quote by science fiction author Theodore Sturgeon, who once said, “Sure, 90% of science fiction is crud. That's because 90% of everything is crud.” Sturgeon himself called this “Sturgeon's Revelation”, and it first appeared in the March 1958 issue of Venture Science Fiction; he gave Sturgeon's Law as “Nothing is always absolutely so.” Oddly, when Sturgeon's Revelation is cited, the final word is almost invariably changed to ‘crap’. Compare Hanlon's Razor, Ninety-Ninety Rule. Though this maxim originated in SF fandom, most hackers recognize it and are all too aware of its truth.
