Lessons from Wikipedia: Keeping information reliable in the digital age

Read a new series to explore how Wikipedia can inspire new standards of knowledge integrity for our times.

On Wikipedia, disagreement is never a sign of failure. It’s evidence that people care deeply about getting the facts right.

Volunteers have debated topics from the seemingly light and mundane—whether there should be a Wikipedia article about Kate Middleton’s wedding dress or if the Bee Gees are a British or Australian group—to more heavy and serious topics like documenting COVID-19. They decide what content to include on Wikipedia based on notability criteria and by following Wikipedia policies. These practices ensure editor independence, invites diverse views, and prevents undue influence from any one person or organization. Even the Wikimedia Foundation, the nonprofit that hosts Wikipedia, has no say in content disputes on Wikipedia.

Instead, editors from around the world debate in the open how an article should describe a contentious topic, which sources best represent the evidence available at the time, or whether a claim meets Wikipedia’s high standard of neutrality. Because of how editors carefully consider these questions, Wikipedia continues to evolve as one of the most reliable sources of information in the world.

So how does that actually happen?

No one decides alone

A** **single editor on Wikipedia cannot unilaterally settle a content dispute, particularly on a contentious topic. Every contribution is transparent to the public and available to review, and every edit is open for more comment and input. Authority on Wikipedia comes from reliable sources and open dialogue—in this way, everyone contributes equally.

When Wikipedia contributors disagree, they explain their arguments on article “talk” pages, where anyone can see and join the discussion. These talk pages are the heart of dispute resolution on Wikipedia; they are public spaces where arguments are examined, evidence is weighed, prior discussions can be reviewed, and consensus can gradually emerge.

This approach prioritizes debate, disagreement, and collaboration. Disputes don’t end when someone “wins”, rather many volunteer editors reach a shared understanding of what the best available sources offer on a specific article or topic at the time.

Relying on reliable sources

Wikipedia’s guidelines encourage editors to focus on verifiability, neutrality, and sourcing—never on personal opinion. Instead of asking “who’s right?”, editors ask “what do the reliable sources say?” Over time, this collective referencing process shapes what reflects the current state of available information.

When a debate on Wikipedia stalls or needs more input beyond talk page discussions—like when consensus could not be reached on if the “Monty Hall problem” is a puzzle of probability or game theory—editors can use a structured process called a “Request for Comment (RfC)”. This helps flag the debate for more members of the Wikipedia community to weigh in on the outcome. RfCs are intended to gather diverse viewpoints, helping to break deadlocks by ensuring more input. RfCs also provide a record for past decisions, so that future decisions can build on the discussions and evaluation that came before it. Most RfCs are structured around a specific question, such as whether a detail belongs in an article or how to interpret a policy, and they are resolved when a clear consensus emerges.​

Radically transparent decision-making

In a time when digital spaces often amplify polarization, Wikipedia shows that transparency and structure can turn disagreement into progress by collecting diverse feedback from many different voices. Research has shown that the more people who take part in building a Wikipedia article, the higher-quality the knowledge becomes and those who participate leave the process less extreme in their views and more open-minded.

Trust in the information ecosystem is built on the willingness of people to carefully debate how to weigh different sources, admit mistakes, and pursue a shared objective of getting to accuracy together. The Wikipedia model works not by avoiding conflict, but by ensuring every conflict is handled openly, civilly, and based on reliable sources.
