The PPP process can deliver three possible outcomes to policy makers:
The University of Michigan, Genetics Public Policy Center, Genetic Alliance for example—in the mode of advocacy groups mobilized around a cause—use a (top-down) "Recitation Model" with an emphasis on public engagement mobilized to bring a group of (demographically non-representative) individuals (lay, experts, policy makers, etc.) together into a guided-focus group discussion designed to deliver some important ideas to policy makers. This process captures what people bring into the room with them (interest, knowledge, etc.). A small amount of directed education also takes place.
The PPP process leads to a more educated policy maker about technical issues and public values. The PPP process also leads to ongoing public education (improved science literacy), and ultimately to a more efficient science and technology policymaking process.
Is the world mired in what might be called a "democratic recession?" US policy makers should view democracy not just as a "right," but also as a "choice." A functioning democracy requires a society-wide agreement on issues of national importance (e.g., genetic discrimination, human biobanks and genetic research databases, genetic enhancement, genetic testing, genome-wide screening) designed to provide checks and balances that disperse political power and protect the rights of minorities.
Scientists tend to treat communication as an after-thought. They’re often not working with social scientists, industry, or organized civic groups to build a channel to the public.
