We investigate whether people attach intrinsic value to freedom and which theoretical rules they implicitly employ to evaluate opportunity sets. To do this, we run a new survey-based study with 4,902 participants across 10 different countries. Our main result is that an overwhelming majority of subjects \textit{reveal} attaching intrinsic value to freedom. We also find that a large majority of subjects use size-based rules to rank sets in terms of freedom, while there is considerable heterogeneity in the theoretical rules they employ to rank sets in terms of welfare. These results are strikingly robust across countries.
