The phrase "more telling" suggests that something is revealing or significant. However, its antonym, "less telling", implies the opposite. It implies that something is vague, indirect, or insignificant. "Less telling" could be used to describe a vague statement that doesn't reveal much information or a subtle gesture that doesn't convey a strong meaning. It's important to pay attention to both "more telling" and "less telling" moments in communication to fully understand the message being conveyed. By recognizing both the revealing and the insignificant, we can better understand the underlying meaning in any situation.
