Why no mirror

The propositions establish implementation conditions and exhibit mechanisms for fixed finite games; none asserts an algorithm, complexity bound, hardness result, or computational construction over encoded instances. The proposed continuum extensions replace individual sequential turns with aggregate reports or representatives, changing the strategic question, and cannot supply the missing computational anchor.

fails bit a — no named computational result to mirror

What the mirror covers

No named result is covered; the propositions concern implementation conditions and fixed mechanism constructions.

The case FOR (proponent)

A plausible high multiplicity setting would be a large review panel choosing among three finalists, with many evaluators sharing the same complete preference function and the same planner-known impartiality and friend/enemy information. A type would be that full description, and \(\mu_t\) the fraction of evaluators of type \(t\). But the paper’s natural mechanisms require jurors to take individual turns. In a nonatomic jury, one evaluator has no effect on the aggregate outcome; replacing each type by a strategic bloc or replacing turns with aggregate reports changes the game the paper studies. So this story does not yet give a continuous problem the authors would clearly recognize as their own.

The paper has no named result about computational complexity or algorithms in the programme’s sense. Its closest results are strategic implementation results:

These propositions characterize when mechanisms exist and exhibit mechanisms for fixed, small games. They do not give a running-time result for a problem on encoded instances. I therefore cannot honestly use any of them as the required computational anchor, or state a continuous problem per anchor. The strongest positive case is only that a large evaluator pool with repeated preference-and-bias types is a conceivable extension of the paper’s setting. Its weakest point is decisive here: the results that might anchor that extension rely on a small sequential jury, and the paper does not establish that their questions or conclusions survive a population continuum.

The case AGAINST (opponent, writing after the proponent)

The paper has no named computational result to mirror. Propositions 1–5 concern whether a rule is implementable for a given finite jury configuration, or exhibit a mechanism for one. Propositions 1 and 2 are presented as corollaries of earlier implementation results; Propositions 3–5 establish limits or constructions within a small strategic game. None states a complexity bound or gives an algorithm over encoded instances. Turning “does a mechanism exist for this jury?” into a decision problem could create a computational project, but it would be a new problem rather than a continuous version of a computational result in this paper.

The strongest upgrade is to ask whether the socially optimal choice rule is implementable for a distribution of juror types, or to synthesize a natural mechanism from that distribution. Repeating complete juror types in a large panel is a plausible high-multiplicity scenario. The obstacle is the paper’s central mechanism: each juror takes an individual turn, and natural implementation requires an equilibrium path on which those individual jurors announce the deserving winner. With a continuum of nonatomic jurors, there is no finite sequential game in which everyone takes one turn. Replacing the turns with an aggregate report rule changes the mechanism being studied.

That replacement also creates a strategic degeneracy. If the outcome depends on the distribution of reports, one juror’s report has measure zero and cannot change the outcome. Under individual Nash behavior, every report is then a best response; in a sequential version, the same problem arises in each continuation. Profiles with different aggregate reports can all be equilibria. A rule that makes the outcome independent of reports cannot select an unknown deserving winner across states. Positive-mass coalition deviations or a strategic player for each type could avoid this, but then blocs or representatives—not the jurors in the paper—are choosing. That adds a new institution and equilibrium concept.

This blocks the proposed extensions of every result the proponent listed. Proposition 3’s failure of natural implementation is about the incentives generated by three individual turns; copying those jurors into a continuum does not preserve that game. Propositions 4 and 5 rely on a particular juror moving first because of a known friend or enemy; a positive mass of jurors with that information does not supply a pivotal first mover. Propositions 1 and 2 likewise rely on individual impartial jurors. Replacing “at least one” with “positive mass” may be a sensible continuum condition, but positive mass still consists of nonatomic individuals, none of whom can affect an aggregate outcome alone.

The review-panel story is credible, and repeated preference-and-bias types make sense. The negative case is weaker against a deliberately redesigned model with type-level representatives or coalition deviations; that could be worth studying in its own right. But it would change the paper’s sequential implementation question, and the paper offers no computational result for it to mirror.

The adversarial triple: the proponent anchors on up to three named results; the opponent sees that case and must defeat every anchor; the judge decides which case convinced it. These are the pipeline’s own outputs, generated by tools/triple_run.py — no human edited them. The paper’s own text is not reproduced here beyond the quoted statement above.
