 One plausible story, then, is that while many of our more reflective and reasoned moral judgments involve autonomous exercises of domain-general intelligence, many other less reflective moral judgments are largely attributable to evolutionary influences—both through direct conditioning of people’s moral judgments by evolved, domain-specific psychological dispositions and through background influences on cultural factors. On this hypothesis, we cannot treat moral judgments as a homogeneous set, but must recognize that they can come about in very different ways, requiring a plurality of explanatory models. While a model of autonomous reasoning might apply to some moral beliefs and behaviors, a model appealing to evolutionary causal influences will apply to others. And often some combination of models may be necessary, as in cases where both evolutionary influences and our own independent moral reflection might lead to similar judgments, overdetermining them.
