Many readers are surprised to hear Atwood's novel labeled science fiction, but it belongs squarely in the long tradition of near-future dystopias which has made up a large part of SF since the early50s. SF need not involve technological innovation: it has been a long-standing principle that social change can provide the basis for SF just as well as technical change. The Handmaid's Tale is partly an extrapolation of Rachel Carson's Silent Spring, attempting to imagine what kind of values might evolve if environmental pollution rendered most of the human race sterile. It is also the product of debates within the feminist movement in the 70s and early 80s
