The surveys were conducted by Princeton Survey Research Associates International (PSRAI). We owe special thanks to Evans Witt and Jennifer Su, who conducted much of preliminary data analysis and contributed their analytical skills throughout.
We owe an enormous debt of gratitude to Volker Grassmuck (University of Leuphana), whose expertise and rigor informs much of study and the German analysis especially.
The final version was much improved by the comments and generous attention of other readers, including Pamela Samuelson, Martin Krestchmer, Sherwin Siy, Mary Madden, Kristoff Grospe, Kristen Thomson, Marcin de Kaminski, Mike Masnick and Leigh Beadon. All remaining flaws are our own.
