# Bandwagon Effect
|
|
|
|
## Definition
|
|
A psychological phenomenon where people adopt beliefs or actions because they see others doing the same, regardless of the underlying evidence. In multi-agent systems, it causes agents to converge on popular answers rather than independently reasoning to correct conclusions.
|
|
|
|
## Risk in Multi-Agent Consensus
|
|
- Agents may be influenced by implicit ordering or presentation of options
|
|
- If one answer appears first or is more salient, later agents may favor it
|
|
- The effect can override actual reasoning
|
|
- Correlated responses reduce the benefit of voting
|
|
|
|
## Prevention
|
|
- Ensure agents are truly independent (no feedback loops)
|
|
- Present information in randomized order where applicable
|
|
- Use diverse models with different training to reduce shared biases
|
|
- Treat the consensus as a blind experiment — agents don't know they're voting
|
|
|
|
## Key Principle
|
|
- Diversity in human systems helps solve novel problems
|
|
- The same applies to LLM ensembles
|
|
- Different models, different fine-tuning, different prompts
|
|
- Maximize variance in responses for maximum cancellation of noise
