Which of the following is a common barrier to effective communication?

Technical jargon is indeed a common barrier to effective communication because it refers to specialized language or terminology that is often difficult for people outside a particular field or expertise to understand. When individuals use technical jargon without considering the audience's background or familiarity with the terms, it can create confusion and misinterpretation of the message. This is particularly problematic in diverse groups or when transmitting important information where clarity is critical.

In contrast, active listening, clarifying questions, and consistent messaging are all practices that facilitate and enhance communication. Active listening involves fully engaging with the speaker, ensuring that their message is understood. Clarifying questions help to confirm understanding and eliminate ambiguity. Consistent messaging ensures that information is conveyed in a uniform manner across different contexts, reducing the potential for misunderstandings. All of these elements work towards improving communication, while technical jargon tends to obstruct it.
