Why it's impossible to agree on what's allowed
Ambiguous rules like “no vehicles in the park” reveal how hard it is to get people to agree on what should be allowed, even in seemingly simple cases such as ambulances, wheelchairs, or memorial tanks. Commenters use this thought experiment to probe deeper issues in online moderation and law: letter vs spirit of the rules, how much specificity helps or hurts, the role of cultural norms and power, and whether broad majorities are “good enough” despite inevitable edge‑case conflict. Many conclude that perfect consensus is impossible at scale, so practical systems must lean on trusted human judgment, transparent processes, and acceptance that some users will always feel treated unfairly.
Ambiguity of “No Vehicles in the Park”
- Many note the game’s rule is intentionally vague; disagreement largely comes from undefined terms: “vehicle”, “in the park”, airspace limits, and edge cases (WWII tank, drones, toys, e‑bikes, wheelchairs).
- Some treat anything transport-like (including sleds, skates, strollers) as vehicles; others restrict “vehicle” to motorized, human‑carrying objects; others focus on current function (tank-as-statue ≠ vehicle).
- Several point out that real parks rarely suffer this level of confusion because social norms, enforcement discretion, and other laws fill in gaps.
Letter vs Spirit of the Rule
- Strong split between “letter of the rule” readers (ambulance clearly violates the rule, though rightly ignored) and “spirit of the rule” readers (ambulance doesn’t violate the purpose of the rule, so count it as allowed).
- Some argue instructions explicitly said to ignore overrides and judge only violation, not desirability; many admit they ignored this as unrealistic or uninteresting.
- This mirrors broader tensions between strict textualism and intent‑based interpretation in law and moderation.
What the Results Say About Agreement
- Several users got 93–100% agreement with the majority per question and see this as evidence that broad consensus is possible even with vague rules.
- Others stress that “agreeing with the majority on each item” ≠ “most people share the same full rule set”; probability of two people matching on all 26 scenarios is low.
- One commenter notes only ~9,400 distinct answer patterns emerged out of ~26M possible, suggesting substantial clustering but still high diversity.
Implications for Moderation and Law
- Many link the game to content moderation: even simple‑sounding rules (“no hate speech”, “no harassment”) have fuzzy borders; users will disagree both on definitions and on enforcement.
- Some emphasize that any large platform must accept controversy and user departures; small, values‑aligned communities with trusted moderators fare better.
- Others highlight legal parallels: “reasonable person” standards, necessity defenses, judge/jury discretion, precedent, and the impossibility of perfectly precise laws.
Critiques and Alternative Framings
- Criticism that the experiment is a “trick question”: it withholds real‑world context (aviation law, exemptions, multiple rules) that would resolve many cases.
- Suggestions that a more informative study would:
- Distinguish “is it a violation?” from “should it be enforced?” with graded consequences.
- Explicitly ask for both “letter” and “spirit” answers.
- Measure intensity of opinion, not just binary choices.
- Some argue the main takeaway should be “rules must be drafted and refined carefully”, not “agreement is impossible.”
