Selecting good sources of information is a critical skill to navigate our highly social world. To evaluate the epistemic reputation of potential sources, the main criterion should be the relevance of the information they provide us. In two online experiments (N = 801), we found that receivers are more thankful toward, deem more competent, and are more likely to request information in the future from sources of more relevant messages-if they know the message to be accurate or deem it plausible. To prevent sources from presenting information as more relevant than it is in order to improve their reputation, receivers lower the reputation of sources sending messages that are more relevant-if-true, if they know the message to be inaccurate. Our research sheds light on the reputational trade-offs involved in choosing what information to communicate and helps explain transmission patterns such as rumors diffusion.
