have preferences induced by general norms. We uncover the deep connections between dominant strategy incentive compatibility (DIC) on the one hand,

and several geometric/functional analytic concepts on the other. Our main results are:

1) Marginal medians are DIC if and only if they are calculated

with respect to coordinates defined by a basis such that the norm is orthant-monotonic in the associated coordinate system.
