Although big data analysis technology can provide some valuable information and insights, speculating on the inside story of government decision-making is a complex and multifaceted behavior, and there are many problems with this approach.： On the one hand, government decision-making is based on extensive information collection, comprehensive consideration, multi-departmental collaboration, compliance with laws and regulations, policy orientation, public interest and other multiple elements, the process is usually open and transparent or guaranteed by corresponding mechanisms. On the other hand, it is inappropriate and potentially illegal to try to use big data to speculate on the inside story of decision-making in an improper way.： 1. **Invasion of privacy and security**: It may involve illegal acquisition and use of citizens' personal information, etc., infringing on personal privacy and information security. 2. **Violation of laws and regulations**: Interfere with the normal government decision-making process and the order of information management, and violate relevant laws and regulations such as confidentiality and data management. 3. **Undermine credibility**: Undermine public trust in government decision-making mechanisms and information disclosure, and affect social stability and governance order. Government decision-making usually gradually discloses relevant information through formal channels. The public should participate in policy discussions and supervision through legal and orderly channels, rather than trying to dig up so-called “inside information” through illegal means. It is more appropriate to respect the government's decision-making process and information management norms, and jointly maintain a good social governance environment.
