  The "Habitual domain" (HD) approach and the "Variational rationality" (VR)
approach belong to the same strongly interdisciplinary and very dispersed area
of research: human stability and change dynamics (see Soubeyran, 2009, 2010,
for an extended survey), including physiological, physical, psychological and
strategic aspects, in Psychology, Economics, Management Sciences, Decision
theory, Game theory, Sociology, Philosophy, Artificial Intelligence,.... These
two approaches are complementary. They have strong similarities and strong
differences. They focus attention on both similar and different stay and change
problems, using different concepts and different mathematical tools. When they
use similar concepts (a lot), they often have different meaning. We can compare
them with respect to the problems and topics they consider, the behavioral
principles they use, the concepts they modelize, the mathematical tools they
use, and their results.
