How politicians evaluate public opinion (POLEVPOP)
In democracies, policies are expected to be
 responsive to public opinion. Extant research showed that responsiveness is
 selective. It varies across issues, time and countries. Yet, how come policies
 vary in their responsiveness has not received a satisfying answer. 
POLEVPOP
 formulates and examines a novel answer to the puzzle why policy responsiveness
 varies. Its core argument holds that politicians evaluate public opinion and
 let their actions—in line with public opinion or going against it—depend on
 their appraisal. When public opinion is evaluated negatively, it has no effect
 on what politicians do; that it is evaluated positively increases the chance
 that politicians act congruently. Politicians’ appraisal of public opinion has
 been completely overlooked as a mechanism bringing about responsive
 representation. Considering it a core factor POLEVPOP examines three matters:
 (1) which criteria politicians use to appraise public opinion; (2) how,
 depending on the opinion content of the message, the channel through which the
 opinion is conveyed and the group from which it comes, concrete public opinion
 signals are evaluated; and, (3) which effect these evaluations have on politicians’
 political action. The central expectation is that public opinion is evaluated
 by politicians based on a consistent and common scoreboard. For instance,
 opinion signals are rated based on their representativity and underlying public
 opinion is evaluated on its quality and its intensity. The project tackles
 these matters drawing on a comparative study in eight different countries
 (Australia, Belgium, Canada, Czech Republic, Israel, Portugal, Switzerland, and
 Sweden). In two consecutive rounds of data gathering, a large sample of
 politicians is surveyed and interviewed, and they are subjected to a series of
 survey-embedded experiments. To put politicians’ behavior in perspective, their
 answers are compared to parallel citizen surveys in all countries.
