Fabricating a false story about a celebrity may have a significant impact on public opinion in the following environments: 1. **A network environment where social media is highly developed and information spreads rapidly**: Information on social media can spread widely and instantly, and false stories can easily spread to a large number of users with the help of hot topics and traffic algorithms, triggering a lot of attention, discussion and secondary dissemination, and quickly forming a storm of public opinion. 2. **A period when the public pays great attention to the celebrity**: For example, when the celebrity has a major event, a new work is released, and other highly anticipated moments, any information related to it will be highly focused, and false stories are more likely to take advantage of the situation and cause a strong response. 3. **An environment where there is a lack of timely clarification of authoritative information and an effective rumor-refuting mechanism**: If there is no reliable channel to refute rumors or correct wrong information in a timely manner, false stories will continue to ferment in an information vacuum or chaos, misleading public opinion. 4. **A public opinion field with group polarization and emotional atmosphere**: When the public is already in an emotional state and easily incited, or when there are fierce confrontations and polarizations between different opinions, false stories are more likely to be used to intensify conflicts, guide public opinion, and amplify their influence.
