Final answer:
Self-criticism is a manifestation of the intelligence of an effective public speaker, allowing for critical self-evaluation and refinement of speaking abilities. It contributes to reflexive communication and ensures the speaker's message is well-received by the audience.
Step-by-step explanation:
An effective public speaker exhibits several manifestations of intelligence, and among them is self-criticism. This trait is essential for a speaker's development because it involves meaningful analysis, examples, explanations, observations, speculation, and honest criticism that lead to purposeful and thoughtful self-evaluation. Self-criticism enables speakers to assess their performance objectively, recognize areas for improvement, and refine their speaking abilities.
Furthermore, an understanding of reflexive communication can enhance the speaker's connection with their audience. Reflexive communication involves not only delivering a message but also being attentive to the audience's responses, both verbal and nonverbal, adjusting the message accordingly.
By being self-critical, speakers can maintain a tone and language choices well-suited to their audience and exhibit an awareness of the rhetorical situation, ensuring that their message is conveyed effectively.
