Sturgeon's law
adage cited as "ninety percent of everything is crap"
Sturgeon’s law is a saying that 90 % of anything is really bad. It was created by Theodore Sturgeon to defend science fiction from people who didn’t like it. It is often quoted as “No doubt 90 % of science fiction is crap then again 90 % of anything is crap”. Since then the saying was used about other things.
