What term describes the phenomenon where people hear mostly echoes of themselves and are rarely exposed to opposing views?

• A. Globalization.
• B. Digital literacy.
• C. Open data.
• D. Echo chamber.

Answer: (D)

An echo chamber describes a situation where the information someone encounters mostly reflects their own beliefs, with opposing views scarce. This happens when algorithms promote similar content, people follow like-minded sources and friends, and individuals tend to seek information that confirms what they already think. Because feeds continually reinforce familiar ideas, people hear mostly echoes of themselves and rarely encounter challenging or different viewpoints. This can lead to stronger biases, less willingness to engage with dissent, and greater polarization. Related ideas include confirmation bias and filter bubbles, which help explain why exposure to diverse perspectives often diminishes. Globalization, digital literacy, and open data describe broader phenomena or skills, not the pattern of a closed information loop that amplifies one viewpoint.
