"Alternative facts" refer to statements that are presented as true but are not supported by objective evidence. This term gained popularity in 2017 when a spokesperson for Donald Trump used it to describe misleading information about the size of the crowd at his inauguration. The phrase highlights the difference between verifiable facts and subjective interpretations. The concept raises concerns about the nature of truth in public discourse. When people accept "alternative facts," it can lead to confusion and misinformation, making it difficult to reach a common understanding on important issues. This phenomenon is often discussed in the context of media, politics, and public opinion.
