The social scientist faces the problem of the appreciation of the distance between his cultural background and the agent's cultural background. We can call this problem the intersubjective difference measurement problem or intersubjective metrology problem. A solution to this is suggested by the recent development of hapiness economics (Frey & Stutzer, 2016). Rejecting the traditional view that the measurement of utility can only be grounded on observable behavior (Robbins, 1932), happiness economics aims at providing an scale of subjective appreciation of happiness (Alexandrovna, 2016). It is reasonable to believe that, if it is possible to measure the distance between subjective degree of happiness, it provides a model for a more general endeavor: to measure the distance between subjective worldviews. The goal of my paper is to discuss the viability of this option.
