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.
