Youth leagues should not offer tackle football to children below high school age. 0.50 Agree Disagree

Topic: Sports · draft Still needs: evidence, objective criteria, testable predictions or a falsifiability test, costs and benefits, interests on either side (listed at the end of the page) · Votes are shown as what people think, next to what the analysis says, and never move a score. · Position on the topic axis (typed, not scored): +55

If you disagree, this page has a column for you. A study, record or dataset for “A child's brain is still developing, and the damage from repeated head hits in tackle football builds up over years, so the earliest hits are the costliest ones”, 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.

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: A child's brain is still developing, and the damage from repeated head hits in tackle football builds up over years, so the earliest hits are the costliest ones.; A young child cannot weigh the risk of brain damage from tackle football, because that harm will not show up until middle age, so adults who will never bear it are making the choice for the child.; Flag football teaches the same footwork, routes and teamwork as tackle football without the collisions, so a child who waits until high school to start tackling misses nothing essential about the sport.; Parents already weigh serious injury risks when they let children ride bikes, ski or play soccer, and tackle football belongs in that same set of family decisions rather than under a league-wide rule.; Learning to tackle while bodies are small and slow teaches safe technique before players grow big enough to do real damage to each other.; Many children who want to play tackle football drop out of the sport when youth leagues offer only flag football, and the fitness and discipline they lose while waiting for high school are real costs..
Bottom line: It turns on whether the long-term harm from repeated head hits in childhood is large enough to override a family's right to choose.

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.

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.
