The Big Picture
You can predict whether a social mechanism (like gossip or reputation) will survive as an agent population grows by splitting its effect into how often information reaches decisions and how agents respond to that information—both parts can be measured before running a costly large simulation.

The Evidence
A single structural quantity (how widely and how long a message is visible) often sets the failure point for gossip: when coverage falls, the mechanism breaks. How social information is presented matters—explicit counts and explicit percentages that encode the same ratio produced different scaling behavior. Directional changes (whether a mechanism grows or shrinks with population) are more reproducible across model versions than exact effect sizes, and the audit flags cases where aggregate predictions are impossible because pathways or gains are unknown.

Data Highlights
1Predicted crossover points in bounded-memory tests were coarse: forecasts were about 2× to 2.5× lower than the observed failure point.
2Experimental probes used n = 24 decisions per cell; count-format presentations showed no stated-size dependence (confidence intervals contained zero) while percentage-format presentations produced significant negative interactions excluding zero.
3Real-world illustration: ICLR submissions grew roughly 40× over ten years, showing how public records and deadline concentration change structural coverage and collective behavior.
What This Means
Engineers building multi-agent systems and evaluation platforms can use the audit to decide before a big run whether a mechanism (gossip, reputation, or public records) will scale or fail, saving compute and design time. Technical leaders and researchers can use the checklist to design information channels or institutions that preserve coordination as populations grow and to diagnose whether an observed change is structural, cognitive, or an observation artifact.

Key Figures
Fig 5: Figure 5: Count and percentage formats lead to different stated-size dependence. (A) Dose lattice in the count format on the primary engine, give rates with n = 24 n=24 decisions per cell. Response tracks the number of reports, while no stated-size dependence was detected in this count-format lattice. Anti-diagonal cells state identical proportions. (B, C) The same lattice with explicit percentages on two model families. The stated size now acts, through a sharp threshold on one engine and a graded curve on the other. (D) Baseline-adjusted report × log N \times\log N interactions with 95% confidence intervals across all six lattices, a post hoc analysis specified after the registered per-lattice fits (Methods). Count-format intervals contain zero on every engine, while both percentage-format interactions are negative and exclude zero. F marks Firth fits under separation.

Absolute threshold predictions are coarse and can be off by a factor of around two, so use the audit to guide which population sizes to test rather than to get a precise cutoff. Results come from one donation-game family, a set of tested wordings, and specific model snapshots—different tasks, prompts, or models may change outcomes. Strong interactions between information pathways can prevent an aggregate prediction; in such cases the audit returns path-level statements or an 'unidentified' verdict rather than a guessed aggregate.

Methodology & More
The paper introduces a practical audit that breaks a social mechanism's aggregate effect into pathway exposures (how often a piece of information is visible at a decision) and per-exposure agent responses (how behavior changes when the information is seen). Structural terms like re-encounter rates and message coverage can often be computed from code before running a full simulation; agent responses must be measured with controlled probes. An aggregate prediction is produced only when the active pathways, their gains, and important interactions are identified; otherwise the audit reports path-level forecasts or marks the aggregate as unidentified. Blackboard Pattern Applied to gossip and a donation game, the audit shows that failure at scale often follows a simple law set by message reach and lifetime: private transmissions lose coverage as population grows, while public records preserve it. The way information is encoded matters—counts versus percentages led to different population-size responses—so prompt and interface design change system-level outcomes. The authors validated pre-run predictions across external code and model families, demonstrated a real-world parallel in conference reviewing where deadline concentration and public records altered behavior, and documented limits: coarse crossover estimates, dependence on tested prompts and models, and inability to make aggregate forecasts when pathway gains are unknown. The framework helps teams predict, design for, and debug scale effects before costly simulations. Tree of Thoughts Pattern
