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: Keeping immigration low helps Japan protect the high level of trust between neighbors and strangers that its widely shared customs and language make possible.; Keeping immigration low keeps Japan's labor market tight, which pushes employers to raise wages, invest in automation, and bring more women and older people into work instead of hiring workers from abroad.; Even a large rise in immigration would only slow Japan's population decline and aging rather than stop them, so it would bring the strain of integrating many newcomers without solving the problem it is meant to solve.; Japan needs more immigrant workers because its care homes, construction sites, and farms already cannot find enough staff, and machines cannot yet bathe a patient or pick fruit well enough to close the gap.; More young immigrant workers paying taxes in Japan would help cover the cost of pensions and health care for its growing number of retirees, easing the pressure to raise taxes or cut benefits.; Rural towns across Japan are emptying out and closing schools and clinics, and immigrants willing to settle in them are the only realistic way to keep those towns alive..
- Bottom line
- The disagreement turns on whether a shrinking, aging country can hold onto its social fabric and still keep its economy and public services running.
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 japan-keep-immigration-low, 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: japan-keep-immigration-low.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.
