Symmetry shifting for monoidal bicategories

We show that every braiding on a monoidal bicategory induces a monoidal structure on its bicategory of monoids, such that if the former is sylleptic or symmetric then the latter is braided or symmetric, respectively. This extends a classic theorem of Joyal and Street for monoidal categories. The proof presented in this paper is an application of the $\mathrm{\infty }$-operadic Additivity Theorem and thereby averts any considerable calculations.
