Here monotonicity means that if preferences update in such a way that they get closerto an outcome then at the new situation this outcome remains chosen. Strong monotonicity requiresfurther that in those cases the outcome at the new profile is a subset of the outcome at the oldprofile. It is shown that only dictatorial preference correspondences are unanimous and stronglymonotone.
