Exposure Taxonomy: Observed, Theoretical, Reported, Anticipated

Four distinct ways to measure AI's reach into an occupation — observed exposure (tasks seen done with Claude), theoretical exposure (tasks an LLM could do), reported exposure (what workers say AI can do today), and anticipated exposure (what they expect in 12 months) — plus their orderings (theoretical > reported > observed), the GDP/experience/automation gradients the AEI survey reveals, and Steele & Cruz's seven-instrument head-to-head showing the instruments cluster by data source rather than by construct, nominate eleven distinct occupations across twelve most-exposed slots, and flip even the *sign* of the exposure-salary relationship by vintage
