While most of the findings are from online policymaking simulation surveys conducted by PPC, some are also derived from the “deliberative polls” conducted by the Center for Deliberative Democracy at Stanford University. In a deliberative poll a representative sample of Americans goes through a process in which they are first polled on key issues using standard poll questions.
They then read briefings on the key issues that have been reviewed by a bipartisan oversight committee. Next, they meet for several days in person, hear from experts on the issues, hear competing arguments and get a chance to discuss the issues. At the end, they are polled again.
CDD final poll results are included in the list of policy positions on this website, noted by (CDD).
