Online-participation heuristic
Cunningham's Law
Posting a wrong answer can attract corrections faster than asking an open question because error gives knowledgeable readers a specific target.
specific contestable claim -> lower correction cost + stronger response motive
The saying is attributed to Ward Cunningham by Steven McGeady. It is not a validated universal law and does not justify deceptive or harmful posting.
An empty question and a concrete wrong claim enter the same community; corrections accumulate, but so do repetition and anchoring risks.

- An empty question and a concrete wrong claim enter the same community; corrections accumulate, but so do repetition and anchoring risks.
A concrete error creates handles for people who know exactly what is wrong.
Correction cards attach to clauses in a flawed post while a parallel open question waits for someone to frame the problem.
What it actually says
The heuristic combines cognitive and social mechanisms: detecting an error can be easier than generating an explanation from scratch, and correction offers status, clarity, or a direct action.
Responsible use is to make a genuine attempt, expose assumptions, and invite correction--not to seed falsehoods. Communities also need citations and revision trails so corrections outrank the original error.
"A useful law compresses a pattern. It does not erase the conditions that make the pattern true."
How the idea developed
The modern form emerged through observation, argument, and later refinement. The timeline separates the first insight from the version now used in textbooks and practice.[1]
Ward Cunningham develops collaborative software and the first wiki.
Steven McGeady publicly attributes the maxim to Cunningham.
Q&A and community systems study answerability, correction, and misinformation.
How the pattern works
The relation becomes useful only when its mechanism, measurement process, and operating range are visible.
Spotting a local error can be easier than producing a full answer.
A claim tells responders where to engage.
Correction can signal expertise or protect group accuracy.
The saying is attributed to Ward Cunningham by Steven McGeady. It is not a validated universal law and does not justify deceptive or harmful posting.
Where it earns its keep
Applications are strongest when the law changes a decision, measurement, model, or experiment rather than merely providing an analogy.
Show your current model
ApplicationProvide a minimal reproducible attempt and uncertainty.
Invite evidence-based correction.
Make revision visible
ApplicationLink corrections to the claim and elevate sourced answers.
Avoid engagement rewards for falsehood.
Where it stops working
Topics with low expertise, high polarization, or weak moderation may produce confident counter-errors rather than reliable correction.
"Lie to get engagement"
Better: False claims can persist, harm, and pollute search."The most corrected answer is true"
Better: Correction volume is not evidence quality.Sources and further reading
