Belief
We should tax property by the value of the land itself, independent of what is or is not built on it. 0.50 Agree Disagree
If you disagree, this page has a column for you. A reason to agree that answers: “Accurately assessing unimproved land value separately from buildings is contentious and technically difficult, which makes a land value tax hard to administer”.

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 →
Not shown: 53 further inputs, each moving it less than any row shown
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.

Evidence Verification Score 0.00 · supporting 0.00 · weakening 0.00. 15 of 15 findings have no source type named yet; 15 have no replication count recorded, so each counts as one study.
Findings that can fail empirically. Each has its own page where its accuracy is argued; the source is shown under it. Bears on says which claim the finding is filed under: this belief, or one of its reasons, in which case it reaches this page through that reason's truth score and is counted there. “Starts at” is where a finding's page begins before anyone argues with it, set by what kind of source it is, how many independent replications exist and how many of them agreed. A finding nobody has classified starts at 0.50, and at 0.50 it contributes nothing however often it is listed.
Interests, Not PositionsConflict resolution framework →
Interests of each side
Interests of supporters
Interests of opponents
Primary conflict pair (computed: the interest with the highest Validity x Drives on each side) Residents of fast-growing cities need sustainable urban development. (0.50 x 0.50) against Longtime homeowners and multigenerational family landholders need traditional ownership models protected. (0.50 x 0.50). 50% of the paired weight sits on the supporting side. This is the one disagreement actually driving the debate: the product uses validity on purpose, so a cover story cannot lead a side and neither can a worthy need nobody is moved by. Validity is whether the need should be honored, argued on its own page and never by the power of who holds it; Drives is whether the need is really why this side holds its position, settled by what the side does. They are different numbers.
Shared interests
| Both sides need functional, livable communities. | 0.50 | |
| Both sides need fair and transparent taxation principles. | 0.50 | |
| Both sides need vulnerable populations protected from undue burdens. | 0.50 | |
| Both sides need economic growth and development. | 0.50 | |
| Both sides need land put to productive use rather than left unused and wasted. | 0.50 |
Best compromise
| Phase the tax in gradually, raising the rate on land and lowering the rate on buildings a little each year. | Rests on Why difficult | 0.50 |
| Let elderly or low-income homeowners defer the land tax increase until they sell the property or die, and exempt active farms and conservation land or tax them at a very low rate so farmers are not forced off their land by neighboring speculative values. | Rests on Why difficult | 0.50 |
| Implement the land value tax in a revenue-neutral way, cutting another tax by a dollar for every dollar the land tax raises. | Rests on Why difficult | 0.50 |
| Cap how much any landowner's tax can increase in a single year during the transition. | Rests on Why difficult | 0.50 |
| Use a split-rate property tax that taxes land at a higher rate than buildings while still taxing buildings somewhat. | Rests on Why difficult | 0.50 |
| Capture land value for the public through a community land trust, or adopt only a small land value tax and use its proceeds for community dividends or visible local improvements so taxpayers see direct returns. | Rests on Why difficult | 0.50 |
| Try the land value tax as a pilot in a limited zone or for a trial period with a built-in review, or adopt it with a sunset clause that requires reauthorization after about ten years. | Rests on Why difficult | 0.50 |
| Combine land value and conventional property taxes in a hybrid model. | Rests on Why difficult | 0.50 |
| Offer tax relief programs for landowners on fixed incomes. | Rests on Why difficult | 0.50 |
| Adjust how agricultural land is valued for the tax. | Rests on Why difficult | 0.50 |
Positions are what people say they want; interests are why. Each interest is a need with a subject (who needs what), and that one sentence is argued two ways that never borrow from each other. Validity asks whether the need should be honored, and is settled on the interest's own page by the mirror test: would the side accept the same need honored for its opponents, and what happens if everyone pursues it? Who holds the need, how many of them there are and how much power they have never count. Drives asks whether this need is really why the side holds its position, and is settled by the side's record, not its rhetoric (the scoring methodology calls it Linkage Accuracy). Score = Validity x Drives. A motive that is real and illegitimate stays in the table with its low validity: it is scored, not deleted, and the same suspicion applies to both sides.

After Allentown, Pennsylvania shifted to a land-heavy tax, 70% of homeowners got a tax cut and building permits in previously stagnant neighborhoods increased by 32%.; After Allentown voters approved taxing land at five times the rate on buildings in the mid-1990s, the city did not need to raise taxes for several years.;

Retirees on fixed incomes who own their homes outright need asset-rich, cash-poor owners protected from financial hardship.; Farmers and ranchers who own the land they work need agricultural and rural land to stay viable.; Longtime residents of neighborhoods where land values are rising need community stability preserved and displacement prevented..
- Bottom line
- The evidence indicates significant promise if a land value tax is done right, and significant pitfalls if it is done poorly.
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.
