媒体与信息系统
In a crisis, what people know depends on news media, social platforms, messaging apps, authority channels and word of mouth. These 系统 can save lives by spreading accurate warnings and guidance, or spread rumours and false information that cost them. This page sets out how information systems work in crises and over time, how information quality and access are measured, and what evidence serves the authorities, media and civil society involved.
Media and information systems in seven parts.
Media and information systems: how the risk develops.
Media and public information as social 系统. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Local news is shrinking
Loss of local journalism leaves communities with fewer trusted sources and less scrutiny of local institutions.
Messaging apps carry crisis information
Private messaging groups spread information quickly, including rumours, and are hard for authorities to monitor or correct.
Platforms amplify what engages
Recommendation systems favour content that draws attention, which can amplify fear, outrage and false claims in a crisis.
Trusted messengers matter
People act on information from sources they trust, such as community leaders, health workers and local media, more than on distant authorities.

专家提出的问题。
- How is the information ecosystem structured, and who controls its key channels?
- What happens to public knowledge when local news declines?
- How do information flows behave during crises, and where do they break?
- Which communities are poorly served by mainstream channels?
- How do economic models of media affect the quality of risk information?
The ecosystem and its fragilities.
Information ecosystems combine professional media, platforms, messaging apps, community channels and authority sources. The decline of local journalism in many places has reduced coverage of local government, hazards and public health. Platforms have become major gatekeepers, and their ranking and moderation choices shape exposure to information. Encrypted messaging networks carry both community support and rumour, and are hard to observe.
During crises, demand for information surges while normal channels may fail through power and network outages. Rumours fill gaps when authority information is slow or distrusted. Language, literacy, disability and connectivity determine who receives timely information. Concentration of ownership and dependence on advertising revenue influence what is covered and how.
Resilient information 系统 share some features: diverse sources, trusted local intermediaries, channels that work without the internet such as radio, information in the languages people speak, and authority communicators who are open about uncertainty and correct themselves quickly. These features can be studied, compared and strengthened.
Public service and community media often play an outsized role in crises because they reach people without internet access and are locally trusted. Their funding and independence are therefore part of a society’s risk infrastructure, a point the field documents with comparative evidence across countries.
Methods and limits.
Ecosystem mapping
Mapping outlets, audiences and flows of information in a place.
Content analysis
Systematic analysis of coverage and narratives; large-scale methods need careful validation.
Audience research
Surveys and qualitative work on how people find and judge information.
Limits: platform data access is restricted, private messaging is largely unobservable, and rapidly changing technology dates findings quickly.
