scores:
- name: definition_precision
  value: 5.0
  max_value: 5.0
  rationale: The definition is highly precise and non-circular, clearly articulating
    the specific requirement that both parties in a barter exchange must simultaneously
    want what the other offers. It captures a distinct economic concept with clear
    boundaries rather than being a vague umbrella term.
- name: source_grounding
  value: 5.0
  max_value: 5.0
  rationale: This concept is directly grounded in Smith's actual text from Book I,
    Chapter 4, where he explicitly discusses the limitations of barter systems and
    the need for coinciding wants. The butcher-brewer example provided aligns with
    Smith's own illustrative approach to explaining this barrier to trade.
- name: domain_placement
  value: 5.0
  max_value: 5.0
  rationale: The placement in the "Exchange" domain is precisely correct, as this
    concept fundamentally concerns the mechanics and limitations of trading relationships.
    It represents a core constraint within exchange systems rather than belonging
    to production, distribution, or other economic categories.
- name: vsm_relevance
  value: 2.0
  max_value: 5.0
  rationale: This entity is largely VSM-neutral as it describes a structural limitation
    of barter systems rather than mapping to specific VSM functions. While it might
    tangentially relate to S1 (operational constraints) or S2 (coordination problems),
    it doesn't naturally align with the VSM's organizational cybernetics framework.
- name: explanatory_value
  value: 5.0
  max_value: 5.0
  rationale: This entity provides exceptional explanatory power by illuminating the
    fundamental mechanism that necessitates the development of money and more sophisticated
    exchange systems. It explains a crucial structural relation that drives economic
    evolution rather than merely naming a surface phenomenon.

# Evaluation: Double Coincidence Of Wants

## definition_precision — 5.0 / 5.0

The definition is highly precise and non-circular, clearly articulating the specific requirement that both parties in a barter exchange must simultaneously want what the other offers. It captures a distinct economic concept with clear boundaries rather than being a vague umbrella term.

## source_grounding — 5.0 / 5.0
