Why does "jargon overload" cause financial communication to fail?

Why: Unexplained technical terms create a comprehension barrier for a lay audience, undermining the goal of clear financial communication. Why the Other Options Are Excluded: •  There is no blanket legal requirement to use jargon in financial communication. •  Jargon does not inherently improve clarity, and can lengthen effective communication by requiring the audience to seek clarification. •  Lay audiences generally respond better to plain language, not technical vocabulary, per the topic's own examples. •  Simple sentences are the opposite of the problem; jargon overload is caused by unexplained technical terms, not by plain, accessible phrasing. Industry Example: Explaining a scheme using "annuitisation" without further explanation, rather than "the part of your savings that becomes your monthly pension," illustrates jargon overload.
