Cities that spend public money on stadiums for professional teams generally get back less than they put in. 0.50 Agree Disagree
If you disagree, this page has a column for you. A study, record or dataset for “Most of the money fans spend at a stadium is money they would otherwise have spent at local restaurants, theaters and shops, so the city gains little that is new”, which rests on argument alone.

Weight for 0.00 · weight against 0.00 · net +0.00
Each reason is a claim with its own page. Score = sign x (2 x Truth - 1) x Conf x Link x Imp x Uniq, and every column is here so the row can be multiplied out and checked. A reason argued false scores negative and counts against the side it is filed on; a reason nobody has argued yet scores exactly 0, and so does one whose own page has no work behind it.
What Would Change the AnswerTruth scores →
Every claim beneath this page held at false and then at true, one at a time, with the whole graph recomputed each time. "If false" and "if true" are where this page’s truth score lands; "Move" is how far apart they are. "If settled" is that same distance with the input’s confidence held at 1, which is what it would be worth once the work behind it is finished, so the gap between Move and If settled is the value of doing that work. This is one input at a time and finds single points of failure; it does not test several inputs moving together, which is how correlated assumptions actually fail.

- Coverage
- Of 6 scored rows, 6 have no linkage page, 6 have no importance page, 6 have no uniqueness page. This page reads 6 other pages. 6 of them are one-sided or empty: Most of the money fans spend at a stadium is money they would otherwise have spent at local restaurants, theaters and shops, so the city gains little that is new.; Team owners keep most of the ticket, parking and concession income through favorable leases, while the public carries the construction debt for decades.; Owners of professional teams can threaten to move the team to another city, which forces cities to bid against each other and hand over far more than the team is worth to them.; A stadium can anchor development in a neglected district, drawing hotels, housing and restaurants that would not have come on their own.; The civic pride and shared identity a home team gives a city are a real return on public stadium spending, and comparisons that count only dollars leave that return out.; The construction jobs, game-day jobs and out-of-town visitor spending a new stadium brings can return as much to a city as the public money it put into the stadium..
- Bottom line
- It turns on whether money spent at a stadium is new money for the city or money residents would have spent somewhere else in town anyway.
Structural Checks
| Finding | How serious | What it means |
|---|---|---|
| Nothing stated would show it false | a note | No testable prediction is listed, so as written there is no observation that would count against this belief. |
Faults the shape of the argument can show without reading a word of it: a claim used to support itself, a conclusion listed among its own premises, the same page counted twice. None of these changes a score. The wiki also specifies pattern-matching the prose for ten named fallacies; that is deliberately not done here, because a matcher looking for “attacking the person rather than the argument” would fire on the central legitimate argument on this whole site, and a score moved by a regular expression has no page to appeal to.

Idea Stock Exchange, belief page cities-spend-public-money, truth 0.50, confidence 32%, revision 42c8344 of 2026-10-04. The revision is what makes this quotable: these numbers move as the argument is worked on, and rebuilding that revision reproduces them exactly.
Every number on this page as data: cities-spend-public-money.json. Constants: K = 1 · UNARG = 0.5 · DEFLINK = 1 · DEFIMP = 0.5 · DEFUNIQ = 1. A reason placed under a conclusion is presumed relevant until a linkage page says otherwise; the burden is on the challenger. The neutral start for importance, the wiki's own rule.
Every value here is computed from the tables above at build time. Nothing is typed.
