It has been shown that anisotropy of homogeneous spacetime described by the
general Kasner metric can be damped by quantum fluctuations coming from
perturbative quantum gravity in one-loop approximation. Also, a formal
argument, not limited to one-loop approximation, is put forward in favor of
stability of isotropy in the exactly isotropic case.
