DESCRIPTION:We propose and study the notion of survey rationalizability. In
  the simplest case of dichotomous attitudinal surveys\, survey rationalizab
 ility means that both questions and ideal views of individuals can be locat
 ed in the real line in a way that individuals endorse questions correspondi
 ng to the upper contour set of their strictly quasi-concave utility. We sho
 w how the relative location of questions can be learnt using a revelation m
 echanism that involves pairs of individuals and triplets of questions\, and
  that the acyclicity of these revelations suffices for rationalizability. W
 e then show that our analysis readily extends to the cases of polytomous su
 rveys and of probabilistic data. We further study the identification of the
  main parameters of these models and show that\, in an exponential version 
 of the probabilistic model\, even the cardinal locations can be fully deter
 mined. We conclude by studying an alternative model of survey responses for
  aptitudes.\\n\\nContact: Nicolas Clootens: nicolas.clootens[at]univ-amu.fr
