There has been much recent interest in questions about epistemic norms of assertion. Is there a norm specific to assertion? Is it constitutive of the speech act? Is there a unique norm of this sort? What is its content? These are important questions, so it's understandable that they have received the attention which they have. By contrast, little attention—little separate attention, at least—has been given to parallel questions about telling: Which norm or norms govern telling, etc.? A natural explanation for this disparity in interest is that it's felt generally to be obvious that there can be no significant distinction between the two types of norms, and hence no need to consider them separately. This paper challenges that general feeling. The first part argues that it's not obvious that the same norms govern assertion and telling. The second part argues that far from being obvious, this idea is mistaken: there are significant differences between the two types of norms.
