What does the "halo effect" imply in public speaking?

The concept of the "halo effect" in public speaking refers to the phenomenon where a speaker's overall positive impression influences the audience's perception of their message. When a speaker presents themselves confidently, appears knowledgeable, and engages the audience effectively, these positive characteristics can create a favorable bias toward the speaker's content. This means that the audience is more likely to view the information being presented as credible and agreeable, even if the content itself may not be as strong. The halo effect highlights the importance of good presentation skills, not only in terms of the material delivered but also in how it is delivered, as positive speaker traits can elevate the audience's reception of the message.
