In ethical speaking, presenting only what you believe is true is paramount because it establishes credibility and fosters trust between the speaker and the audience. When a speaker conveys information they genuinely believe to be accurate, they are more likely to uphold the integrity of their message. This approach ensures that the information shared is not misleading, thus respecting the audience's right to receive honest and factual content. Ethical speaking encourages the dissemination of knowledge based on truth rather than manipulation or emotional exploitation.

The other options highlight practices that compromise ethical standards. Appealing to people's fears can lead to panic or misinformation, while overlooking facts for the sake of a compelling narrative risks propagating falsehoods. Additionally, presenting beliefs without regard for factual evidence undermines the foundation of logical discourse, potentially leading to disinformation. Thus, adhering to the principle of presenting what is truly believed to be accurate is fundamental to ethical communication.
