AI agents exhibit herd behavior, leading to inefficient resource allocation

A new study published on arXiv explores how AI agents, when built on shared models, exhibit herd behavior, leading to inefficient resource allocation. In a congestion game simulation, AI agents warned about potential crowding on one road overwhelmingly chose that path, increasing average travel time. This pattern persisted even when agents could individually save time by switching to a less-crowded alternative. While human groups showed more balanced choices, mixed groups with a higher proportion of AI agents also displayed imbalance, with humans increasingly opting for the road agents avoided. AI

IMPACT Shared AI models can lead to collective inefficiency and unequal burden distribution, highlighting the need for careful evaluation of AI agent populations.

    Warned alike, AI agents avoid the less-crowded road while people take it

    arXiv:2609.30883v1 Announce Type: cross Abstract: AI agents built on a few shared models increasingly act for many people. A shared forecast about others can align their choices and change how scarce capacity is allocated. We tested this feedback in a two-road congestion game. Ad…
