The Electoral Business Cycle of Wikipedia: What Elections Reveal About Partisanship, the Public's Attention, and the Production of Political Knowledge
By analyzing 1.8 million edits to U.S. Congress members' Wikipedia pages, this study reveals that while reader interest remains steady for both sitting and retired politicians, editor activity disproportionately favors current officeholders, creating a structural bias in decentralized knowledge systems where information production lags behind public attention once institutional power is lost.

The Big Idea: The "News" vs. The "Notebook"
Imagine Wikipedia as a giant, shared notebook where volunteers (editors) write down facts about politicians, and the general public (readers) comes to read them.
Usually, we think that if people are curious about a politician, volunteers will rush to write more about them. It's a simple loop: Curiosity drives Writing.
This paper argues that the loop is actually broken. It shows that Curiosity does not always drive Writing. Sometimes, people keep reading about a politician long after the volunteers have stopped writing, simply because there is nothing new to write about.
The Main Discovery: The "Off-Ramp" Effect
The researchers looked at what happens when a U.S. Member of Congress (MC) leaves office (either by losing an election or retiring). They compared two groups:
- Sitting Members: Politicians currently in office.
- Former Members: Politicians who just left office.
The Finding:
- The Readers: The public visits the Wikipedia pages of both groups at almost the exact same rate right after an election. People are equally curious about the winners and the losers.
- The Writers: The volunteers update the pages of the winners much faster. But for the losers/former members, the writing slows down dramatically (about 39% slower).
The Analogy:
Think of a politician's Wikipedia page like a live sports broadcast.
- Sitting Members are the players currently on the field. Every time they score a point, make a play, or get a penalty, the commentators (editors) rush to update the scorecard. The game is happening, so the updates are constant.
- Former Members are the players who just left the field. The fans (readers) are still watching the replay and talking about the game. But the commentators stop updating the scorecard because no new plays are happening. The players aren't scoring anymore, so there is nothing new to report, even though the fans are still watching.
Why Does This Happen? (The "Supply" Problem)
The paper calls this the "Supply-Side Asymmetry."
- Demand (Readers): People want to know about politicians regardless of whether they are currently in charge.
- Supply (Writers): Volunteers can only write about things that actually happen.
- Winners get new jobs, join new committees, vote on new laws, and hire new staff. These are "documentable events." They are the raw material for Wikipedia.
- Losers/Retirees stop doing these things. They don't vote, they don't get committee assignments, and they don't hold press conferences. The "raw material" dries up.
The Metaphor:
Imagine a bakery (Wikipedia).
- The Customers (Readers) are hungry for bread (information) about a specific baker (politician).
- The Bakers (Editors) are willing to bake, but they need flour (new facts) to do it.
- When a baker wins an election, the flour truck arrives every day with fresh ingredients (new votes, new speeches). The bakers bake constantly.
- When a baker loses, the flour truck stops coming. The customers are still standing in line waiting for bread, but the bakers can't bake anything because the supply of flour has run out.
Other Interesting Findings
1. Elections are a "Recruitment Drive"
Just like a big concert attracts new fans, elections attract new Wikipedia editors. The paper found that right after an election, the people editing these pages are less experienced and more politically passionate. They are drawn in by the excitement of the event, not by a long-term love of history.
2. The "Moderate" Effect
Surprisingly, the biggest surge in writing happens for moderate politicians, not the extreme ones.
- Why? Extreme politicians might get more news coverage, but moderate politicians are the ones getting the steady, boring, "bureaucratic" updates (like committee assignments and routine votes) that volunteers love to document. The "boring" institutional work creates the most new facts.
3. Quality Doesn't Drop
Even though many new, inexperienced editors show up after an election, the quality of the writing doesn't get worse. The paper suggests that experienced "gatekeeper" editors quickly fix any mistakes, acting like a quality control team that cleans up the mess the new recruits make.
The Bottom Line
The paper concludes that online knowledge isn't just about what people want to know. It is also about what exists to be written.
If a politician leaves office, the "information pipeline" shuts off. The volunteers stop writing because the politician stops making news, even though the public keeps reading. This creates a structural bias: We have the most up-to-date, detailed information about people who currently hold power, and less information about those who used to hold it, simply because the "facts" stop flowing.
