Cunningham’s law
Cunningham’s law holds that the best way to get the right answer on the internet is not to ask a question, it’s to post the wrong answer. It is attributed to Ward Cunningham, inventor of the wiki, though he has said he never actually made the claim in those words; the phrasing was coined by Steven McGeady, who attributed it to Cunningham in a 2010 discussion.
The observation captures a real asymmetry in how people respond online. Asking an open question often draws silence, because answering well takes effort and no one feels a particular obligation to supply it. Posting a confident but wrong statement draws a much faster, more energetic response, because correcting someone is a smaller effort than composing an answer from scratch, and the sense of catching an error is its own motivation.
The law is invoked well beyond its origin on wikis and forums. Deliberately stating a plausible wrong answer, or a strawman position, is a recognized tactic for drawing out an expert who would not otherwise have bothered to respond to an open question. It also serves as a caution: confidently wrong content spreads and gets corrected less reliably than the law’s own catchiness suggests.
