Low-Cost Words: Why Do We Use Them? -- The Practical Value of Short Responses in Everyday Conversation --

This paper examines “Low-Cost Words,” short conversational expressions that allow people to respond without spending much effort on explanation or deliberation. Examples include “Fine.”, “Sure.”, “Whatever.”, and “Maybe.” The paper argues that such expressions are not necessarily careless or poor communication. They may be practical tools for keeping everyday conversation simple and moving forward. It also considers the risk of overinterpreting these short responses. If a speaker uses a low-cost expression, perhaps the listener can also choose a low-cost interpretation rather than searching for hidden meanings. The paper suggests that good communication does not always require maximum clarity or explanation. Sometimes, not explaining everything—and not overinterpreting everything—may itself be useful.
