Understanding "Why:" How Implicit Questions Shape Explanation Preferences

Adults and children 'promiscuously' endorse teleological answers to 'why' questions-a tendency linked to arguments that humans are intuitively theistic and naturally unscientific. But how do people arrive at an endorsement of a teleological answer? Here, we show that the endorsement of teleological answers need not imply unscientific reasoning (n = 880). A series of experiments show that (a) 'why' questions can be understood as a query for one of two distinct kinds of information and (b) these "implicit questions" can explain adults' answer preferences without appeal to unscientific worldviews. As a strong test of this view, we show that people endorse teleological answers that can answer relevant (implicit) questions about something's purpose, even when those answers are explicitly non-causal. Thus, we argue that endorsement of teleological answers does not necessarily equate to the endorsement of teleological 'explanations': Instead, explanation preferences may simply be an indication of people's pragmatic expectations about the questions that others ask. This view reframes how we should think about explanation preferences in general, while also offering practical insight into the pragmatics of question asking.
