  rationale: The definition is highly precise and non-circular, clearly explaining
    the specific mechanism of tontines where survivors inherit deceased participants'

    instrument rather than a vague concept.

    method and explains the psychological factors that make them profitable for governments.
    The definition accurately reflects Smith's treatment of the topic.

  rationale: '"Regulation" is appropriate since tontines are a government policy tool

    precise domains. The placement is reasonable given the regulatory framework required
    for such schemes.'

  value: 3.0
  max_value: 5.0
  rationale: Tontines map moderately well to S3 (internal regulation) as a government
    revenue collection mechanism, and potentially to S4 (intelligence) regarding how
    governments adapt their financing methods. However, the mapping is not as natural
    as for core operational or regulatory concepts.

  value: 4.0
  max_value: 5.0
  rationale: This entity provides good explanatory value by illuminating a specific
    mechanism of government finance and revealing Smith's insights about how psychological
    biases (overestimating longevity) can be leveraged for public revenue. It demonstrates
    concrete policy implementation rather than just naming a surface phenomenon.

# Evaluation: Tontines

## definition_precision — 5.0 / 5.0

The definition is highly precise and non-circular, clearly explaining the specific mechanism of tontines where survivors inherit deceased participants' annuities until one person receives all payments. It captures a distinct financial instrument rather than a vague concept.

## source_grounding — 5.0 / 5.0

This entity is well-grounded in Smith's actual discussion of tontines in Book V, Chapter 3, where he explicitly analyzes them as a government revenue method and explains the psychological factors that make them profitable for governments. The definition accurately reflects Smith's treatment of the topic.

## domain_placement — 4.0 / 5.0

"Regulation" is appropriate since tontines are a government policy tool for raising revenue, but "Public Finance" or "Government Revenue" might be more precise domains. The placement is reasonable given the regulatory framework required for such schemes.

## vsm_relevance — 3.0 / 5.0

Tontines map moderately well to S3 (internal regulation) as a government revenue collection mechanism, and potentially to S4 (intelligence) regarding how governments adapt their financing methods. However, the mapping is not as natural as for core operational or regulatory concepts.

## explanatory_value — 4.0 / 5.0

This entity provides good explanatory value by illuminating a specific mechanism of government finance and revealing Smith's insights about how psychological biases (overestimating longevity) can be leveraged for public revenue.
