We solve the effective Dirac equation for massless fermions during inflation in the simplest gauge, including all one loop corrections from quantum gravity. At late times the result for a spatial plane wave behaves as if the classical solution were subjected to a time-dependent field strength renormalization of Z2(t)=1-174πGH2ln(a)+O(G2). We show that this also follows from making the Hartree approximation, although the numerical coefficients differ.
