  1. NSF SES 0938099 Early Warnings for Nanotechnology Risk Communication: Benefit Tenacity or Risk Betrayal? • Acceptability ratings shift as information changes • Change is greater when benefit or safety info is given 1st & risk info 2nd (p=.03) • Differences are explained by two reactions: stronger 2-step movement from benefit to risk info; and lesser (1-step) movement from risk to benefit. • Findings imply risk & benefit judgments are malleable so far but risk only information will likely backfire given stronger response to R-B order. findings Data from 2008 US national survey (n=1100). Satterfield, Theresa, Joseph Conti, Barbara Herr Harthorn, & MilindKandlikar. Dec 2010. “Early Warnings for Nanotechnology Risk Communication: Benefit Tenacity or Risk Betrayal?” under review, Environmental Science and Technology.
