Economic complexity inferred from patterns of productive activities is a proxy for underlying capabilities rather than a direct inventory of those capabilities.

  Yet the ubiquity of an industry is hardly a clean measure of the knowledge and knowhow it requires.

  This is not because the activities are themselves the factors but because if activities require many factors their geographic distribution will act as a barcode or fingerprint telling us about their factors.

  TITLE: Complexity measures are maps, not capability inventories. BODY: Observing which places produce which products can reveal patterns consistent with underlying complementary capabilities. Hidalgo combines product ubiquity and producer diversity to avoid equating simple rarity, such as a scarce ore deposit, with technical sophistication. The resulting indicators compress indirect evidence; they do not enumerate skills, institutions, tooling, or causal bottlenecks. SCOPE: Measurement logic, not a finding about returns or human welfare. IMPLICATION: Use the map to select diligence questions, then investigate actual teams, suppliers, processes, and markets. A complexity ranking cannot price a company, prove a colony self-sufficient, or establish equitable distribution. PRIMARY-RESEARCH GAP: Validate predictive performance and confounds before quantitative use.
