  Feminist and non-feminist philosophers of biology have identified a range of problems common among much research in sociobiology and evolutionary psychology. (The list below is primarily drawn from Bleier 1984; see also Anne Fausto-Sterling 1997a, b, 2000; Kitcher 1985 and Sterelny and Griffiths 1999 offer a good overview and introduction to the non-feminist literature.) These problems include kinds of bias as well as methodological challenges.
