In this paper, we argue that, in two dimensions, the weak localization of bosons, which occurs on the insulating side of the superconductor-insulator transition, is characterized by \ensuremathρ\ensuremath∼ln(1/T), as compared to \ensuremathσ\ensuremath∼lnT for fermions. This unconventional behavior is tied to the diffusion pole of the delocalized (uncondensed) vortices.
