+# 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
