# Groupthink ## Definition A psychological phenomenon in which a group of individuals prioritizes consensus and harmony over critical evaluation of alternatives, leading to poor decision-making. In multi-agent systems, it occurs when agents influence each other rather than making independent judgments. ## Risk in Multi-Agent Consensus - If agents have feedback loops between them - Earlier agents' conclusions influence later agents - The group converges on the first plausible answer rather than truth - Results become correlated, defeating the purpose of voting ## Prevention - Agents must run like a **blind experiment** — no communication between them - Same input provided independently to each agent - No knowledge of what other agents concluded - Results aggregated only after all agents have responded ## The "Blind Experiment" Principle - Agents should not know they're part of a consensus - Each agent should independently evaluate the same input - Only the aggregator knows the full set of responses - This maximizes diversity and minimizes correlation ## Related Concepts - [[Bandwagon Effect]] - [[Multi-Agent Consensus]] - [[Sycophancy]]
