What is 'bias by omission' and provide an example.

• A. Leaving out information that would alter perception; e.g., omitting opposing viewpoints in a news report
• B. Including every available viewpoint
• C. Verifying all statements with sources
• D. Presenting equal weights to all sides

Answer: (A)

Bias by omission happens when information that could change how someone understands a topic is left out. In media, this often shows up as leaving out opposing viewpoints, evidence, or context so the story seems more favorable to one side. For example, a news report about a new policy might quote only supporters and omit critics or data about potential downsides, making the policy appear beneficial even if a fuller, balanced view would show more nuance. This isn’t about lying; it’s about shaping perception by not presenting the full picture. You can spot it by noticing missing perspectives, incomplete data, or important caveats that would change the interpretation.
