 Like Adam Smith’s view of the invisible hand regarding altruism and the public good, rationalists can interpret Hull’s account as broadly Hegelian in the sense that the rationality of science emerges (insofar as it does) from the complex social interactions of scientists and groups of scientists going about their normal business in ordinary ways that satisfy community norms and incentive structures, not from their explicit intentions to make rational decisions. While Hull gave close attention to these social interactions and to the institutions that enable them, he claimed that his appeal to social factors was internal to science rather than external.
