One loop electroweak radiative corrections to left-right parity-violating Mo/ller scattering ({ital e}{sup {minus}}{ital e}{sup {minus}}{r_arrow}{ital e}{sup {minus}}{ital e}{sup {minus}}) asymmetries are presented. They reduce the standard model (tree level) prediction by 40{plus_minus}3{percent} where the main shift and uncertainty stem from hadronic vacuum polarization loops. A similar reduction also occurs for the electron-electron atomic parity-violating interaction. That effect can be attributed to an increase of sin{sup 2}{theta}{sub {ital W}}({ital q}{sup 2}) by 3{percent} in running from {ital q}{sup 2}={ital m}{sub {ital Z}}{sup 2} to 0. The sensitivity of the asymmetry to {open_quote}{open_quote}new physics{close_quote}{close_quote} is also discussed. {copyright} {ital 1996 The American Physical Society.}
