 The adept use of quantitative methods may ameliorate these worries to some extent. If populations are recognized as heterogeneous then researchers might engage in further research on subpopulations. Some aspects of the problem of erasure of difference could be addressed, but which characteristics indicate relevant subpopulations will require attention to the lived experience of those who are studied. The need to identify relevant subpopulations reinforces a need for pluralism regarding methods, since recognition of relevant difference depends on the sort of scrutiny most frequently provided through qualitative methods. Recent feminist attention to intersectionality and the ways power differentially structures society through gender, race, ability, sexuality, socioeconomic class, ethnicity, and other salient features of individuals raises a further worry. It is not entirely clear how a subpopulation strategy can address social justice issues intertwined in this way. There is some recent research that attempts to address intersectionality. Bright, Malinsky, and Thompson (2016) offer one approach to examining intersectional causality, for example. But intersectional effects cannot be understood as additive—once again counting against reliance on exclusively quantitative approaches. Finally, there is the problem that further partitioning of the reference class may also decrease the sample size and thus undermine the power of the method. In any case, these worries further support the feminist intuition that methods must be chosen consciously and with attention to the aims of research.
