How Novices Interpret Generalizations and How Experts Use Them

Generalizations, such as "ducks are birds" and "ducks carry avian flu," are a common way of conveying information about the world, yet their implied prevalence-how broadly they should be applied-can vary widely. To interpret how broadly a generalization should be applied, listeners rely on prior knowledge. Listeners who have considerable experience ("experts") with the subject being discussed may thus interpret a generalization differently than those without such experience ("novices"). In the present study, we investigated the ways in which experts and novices differ in how they interpret generalizations, using the esport League of Legends as a cultural microcosm. In the process, we investigated the extent to which expert listeners discount generalizations with which they disagree. We found that novices tended to interpret generalizations more broadly than experts, with only experts adjusting their interpretations based on the context. We also investigated whether expert speakers, when addressing novices, avoid generalizations that novices are likely to interpret differently. In line with research investigating the curse of knowledge and the challenge of designing utterances for specific audiences, we found that speakers did not adjust their use of generalizations when explicitly told that their audience was inexperienced. Taken together, these results point to novice listeners interpreting generalizations as applying more broadly than expert speakers intend. Future research can help clarify the practical impact of such a mismatch by examining how generalizations are used in relation to speakers' and listeners' goals.
