In order for a testimony to be persuasive, it should have which of the following characteristics?

For testimony to be persuasive, it is essential that it is unbiased and current. Unbiased testimony lends credibility and objectivity, allowing the audience to trust the information being presented without questioning the motives or perspectives of the person providing the testimony. This is particularly important in public speaking, where the speaker's aim is to inform or persuade an audience effectively.

Current testimony ensures that the information is relevant and reflects the most recent developments or understanding surrounding a topic, which enhances the speaker's authority and the relevance of the argument being made. In fast-changing fields, such as technology or health, using outdated or biased information can weaken a speaker's position and fail to resonate with the audience.

While a testimony that is factual and meaningful can also be persuasive, it may not carry the same weight if the source is biased or the information is outdated. Therefore, ensuring that testimony is both unbiased and current is crucial for enhancing its persuasive power.
