“…One of Eleanor Singer’s key contributions to the survey methodological literature—and, indeed, social science literature more broadly—relates to the issue of informed consent. Her contributions in this area covered a wide range of topics, including the effect of the consent request on survey participation (e.g., Singer 1978, 2003; Singer, von Thurn, and Miller 1995; Sakshaug et al 2016), consent to paradata capture (Singer and Couper 2010; Couper and Singer 2013), and attitudes toward administrative data linkages (e.g., Singer, Bates, and van Hoewyk 2011). A core element underlying her work was that the issue of consent in whatever form is not only an ethical one but is also subject to empirical investigation.…”
