Longer prison sentences generally make communities safer. 0.50 Agree Disagree
If you disagree, this page has a column for you. A study, record or dataset for “A person who is in prison cannot commit crimes on the street, and every year added is a year the community is protected from that person”, which rests on argument alone.

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.

What this page needs right now

|---|---|---|---|
| 1 | A study, record or dataset for “A person who is in prison cannot commit crimes on the street, and every year added is a year the community is protected from that person”, which rests on argument alone | Evidence Ledger | anyone with the source |
| 2 | A measurement both sides would accept in advance, with the reading each side predicts | Objective Criteria | anyone who can name a yardstick the other side would sign |

- 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: A person who is in prison cannot commit crimes on the street, and every year added is a year the community is protected from that person.; Adding years to a sentence raises the price of getting caught, and a higher price makes some people decide the crime is not worth it.; A few repeat offenders account for a large share of crime, so holding those people longer removes a large share of harm.; Most people age out of crime on their own, so extra years are mostly served by people who would have stopped anyway, at great cost and for no safety gain.; Prison teaches criminal skills and cuts jobs and family ties, so people released after long terms often come out more dangerous than they went in.; The money spent on extra years of prison could pay for more officers on the street, and being likely to get caught deters more than the length of the sentence..
- Bottom line
- The disagreement turns on whether the extra years are served by people who would have kept offending or by people who would have stopped 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 longer-prison-sentences-generally, 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: longer-prison-sentences-generally.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.
