Low panel cumulative response risk

Large public‑opinion panels increasingly report very low cumulative recruitment/response rates; a 3% cumulative response rate (as Pew does here) raises the risk that headline margins of error understate nonresponse bias and that weighting cannot fully recover representativeness. Policymakers and reporters should treat panel estimates as conditional on recruitment and attrition patterns, not as simple random‑sample analogues. — This matters because many policy debates and media stories rely on single survey waves; low cumulative response rates change how much weight those results should carry in public discussion and decision‑making.
