- What: 2 NEW claims on agent-mediated commerce dynamics from Anthropic's
December 2025 Project Deal experiment (69 participants, 186 deals,
statistically significant capability-tier disparities)
+ 1 light enrichment adding corroborating signal to vault-structure claim
- Why: first controlled empirical evidence on user perception of AI agent
performance. Opus agents extracted $2.68 more per sale / paid $2.45 less
per purchase than Haiku agents (p<0.05), but users rated fairness
identically across tiers. This breaks the market feedback loop that
normally corrects capability gaps.
- New claims:
* users cannot detect when their AI agent is underperforming because
subjective fairness ratings decouple from measurable economic
outcomes (experimental, ai-alignment)
* agent-mediated commerce produces invisible economic stratification
because capability gaps translate to measurable market disadvantage
that users cannot detect and therefore cannot correct through
provider switching (speculative, ai-alignment)
- Enrichment: vault-structure-vs-prompt claim gets tangential empirical
signal from Project Deal finding that stylistic negotiation prompts
had minimal effect while model capability dominated
- Connections: strengthens existing Moloch claims (invisible coordination
failures), four-restraints erosion (user rationality check eliminated),
and complements the x402/Superclaw payment infrastructure claims in
internet-finance
