Belief
We should keep men out of women's sports. 0.50 Agree Disagree
If you disagree, this page has a column for you. A reason to disagree that answers: “Male puberty gives advantages in bone density, lung capacity, and muscle mass that often last even after hormone therapy, which makes competition against women unfair”.

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.

Evidence Verification Score 0.00 · supporting 0.00 · weakening 0.00. 3 of 3 findings have no source type named yet; 3 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

|---|---|---|---|---|
| Female athletes need a level playing field. | 0.50 | 0.50 | 0.25 | |
| Parents need scholarship opportunities for their daughters to be protected. | 0.50 | 0.50 | 0.25 | |

Interests of opponents
| Interest (a need; its page argues validity) | Validity | Drives | Score | Value |
|---|---|---|---|---|
| Transgender athletes need social integration and affirmation. | 0.50 | 0.50 | 0.25 | |
| Activists need discrimination to be prevented in all public spheres. | 0.50 | 0.50 | 0.25 | |
| Sports organizations need to expand participation and stay relevant. | 0.50 | 0.50 | 0.25 |
Primary conflict pair (computed: the interest with the highest Validity x Drives on each side) Female athletes need a level playing field. (0.50 x 0.50) against Transgender athletes need social integration and affirmation. (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 people to be able to participate in sports. | 0.50 | |
| Both sides need as many people as possible to be able to compete. | 0.50 | |
| Both sides need athletes to be safe. | 0.50 |
Best compromise
| Keep a female category for biological females and convert the male category into an open category for all athletes regardless of sex or identity. | Rests on Why difficult | 0.50 |
| Create competition classes based on testosterone levels or other body measurements, similar to weight classes in wrestling. | Rests on Why difficult | 0.50 |
| Allow full inclusion in youth and recreational sports, where the social value is high, but apply stricter biological requirements at elite and Olympic levels. | 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.

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.
