Human to Logic Ratio
Arco's primary market selection metric — the proportion of a business's gross margin consumed by human labour costs, used to identify industries where the Operational Arbitrage available to an autonomous competitor is structurally large.
Extended Definition
The Human-to-Logic Ratio measures how much of a market's value creation depends on human coordination rather than deterministic logic. In a high Human-to-Logic market, the incumbent's cost structure is dominated by wages, management overhead, and the coordination infrastructure required to keep human workers aligned. In a low Human-to-Logic market, technology or capital is already the primary cost driver, which means the arbitrage available to an autonomous competitor is smaller and the structural advantage harder to sustain.
Related Terms
- Operational Arbitrage — The Human-to-Logic Ratio is the primary input to Operational Arbitrage: a ratio above 60% of gross margin in human labour costs confirms the arbitrage is structurally large enough to justify an autonomous build.
- Operational Drag — Operational Drag is the internal expression of a high Human-to-Logic Ratio: the non-revenue-generating work that consumes capacity because the business's logic is implemented in people rather than systems.
- Coordination Tax — The Coordination Tax is the overhead component of the Human-to-Logic Ratio: the alignment cost that accumulates when human labour is the primary operational unit.
- Proven Market — A Proven Market with a structurally high Human-to-Logic Ratio is Arco's target: stable demand and significant coordination overhead confirm that the arbitrage is both available and durable.
