BuzzFeed News consulted with four leading social scientists about the analysis methodology. Three of the experts — Alison Morantz (Stanford University), George Garcia (Stanford University), and Charlene Harrington (University of California, San Francisco) — have experience analyzing ICFs specifically. A fourth, David Stevenson (Vanderbilt University), has done similar analyses for nursing homes. All of them said the federal data was a valid source to use for our analysis, that its limitations do not bias the results, and that our methodology was sound.
