What is the purpose of maintaining a neutral facial expression while listening?

Maintaining a neutral facial expression while listening serves the purpose of ensuring understanding. A neutral expression allows the listener to focus on the content of the message without conveying prejudice or emotional bias, which can otherwise distort the reception of information. By not reacting overtly with frustration, excitement, or surprise, the listener can absorb what is being communicated more effectively. This approach fosters a more objective engagement with the speaker's words and helps in accurately processing and interpreting the information shared.

In contrast, appearing disinterested can hinder communication and may discourage the speaker. Mirroring the speaker with facial expressions could help convey empathy or understanding but may not directly contribute to digestion of the message itself. Distracting the speaker is counterproductive and would only create barriers to effective communication.
