Laboratório do futuro dos media

Information ecosystems decide what people know about risk: which warnings reach them, which claims they believe and which institutions they trust. This lab studies news, platforms, recommender sistemas, synthetic media and verification practice, and tests media innovations before they scale. This page sets out how misinformation and information gaps develop and spread, how interventions are evaluated, and who decides on the evidence.

02A pergunta

Future of media lab: how the risk develops.

Information ecosystems and responsible media innovation. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mecanismo

Amplification by design

Ranking sistemas optimise for engagement, and content that provokes strong reactions can travel further. Small changes in ranking rules alter what large audiences see, which makes platform design a research object in its own right.

Mecanismo

Synthetic media lowers the cost of deception

Generated images, audio and video can impersonate people and events cheaply. Provenance standards and detection help, but neither is complete, and the existence of fakes also lets genuine evidence be dismissed.

Mecanismo

News deserts and trust gaps

Where local journalism closes, fewer sources report on councils, courts and hazards. Gaps are filled by rumour or partisan content, and trust in institutions shapes how warnings are received when they arrive.

Mecanismo

Interventions can backfire

Labels, corrections, prebunking and friction aim to reduce false beliefs. Effects measured in surveys may fade, may not change behaviour, or may raise scepticism of accurate content too, which is why field evaluation matters.

03Simulador

Stocks, fluxos, atrasos e um limiar de rutura.

Dois stocks, a pressão e a capacidade de adaptação, ligados por um ciclo de crescimento que se reforça, uma resposta de equilíbrio com atraso e danos quando a pressão ultrapassa a capacidade; para lá do limiar, o sistema pode bascular. Modelo didático com valores ilustrativos declarados, não uma previsão.

09Questões centrais

What experts ask about information ecosystems.

  • How do accurate and inaccurate claims spread, and what slows each?
  • Which sources do different communities trust during an emergency, and why?
  • How do recommendation sistemas and platform design shape what people see?
  • Which corrections, labels or warnings change belief or behaviour, and for how long?
  • How can synthetic media be detected, and what are the limits of detection?
10Mecanismos e fatores

How information systems behave and fail.

Information spreads through networks of people and platforms. Network science shows that a few highly connected nodes can make diffusion fast and that clustering can create communities where some claims circulate and others do not. Platform design adds feedback: content that draws engagement is shown more, and engagement does not track accuracy.

Trust is a central variable. During disasters and health emergencies, people combine authority warnings with what they hear from family, local leaders and online sources. Where trust in institutions is low, accurate warnings may be ignored and rumours fill the gap. Misinformation, shared in error, and disinformation, shared deliberately, have different drivers and call for different responses.

Generative AI lowers the cost of producing convincing text, images, audio and video. This affects both the volume of misleading content and the credibility of genuine evidence, which can be dismissed as fabricated.

11Métodos e dados

Research methods and their limits.

  1. 01

    Content and network analysis

    Mapping how material moves across accounts and platforms. Platform data access is restricted and changes, which limits replication.

  2. 02

    Survey and panel research

    Measuring trust, exposure and belief over time. Self-reports are imperfect and samples may miss key groups.

  3. 03

    Randomised experiments

    Testing labels, corrections and warning formats under ethics review. Laboratory effects may differ from real-world use.

  4. 04

    Detection evaluation

    Testing tools that identify synthetic media, using machine learning methods. Detection is an arms race and accuracy declines as generators improve.

Research on information is itself sensitive. The lab is designed to protect participant privacy, avoid amplifying harmful content and respect freedom of expression.

14Perguntas

Perguntas e respostas.

Why not simply measure how much misinformation exists?
Because prevalence depends on definitions and sampling. Exposure, belief and behaviour are separate questions, and the evidence for each comes from different designs.
Do corrections work?
In experiments, corrections tend to reduce false beliefs, but effects vary, fade and do not always change behaviour. Field evidence with behavioural outcomes remains limited.
How do researchers get platform data?
Through platform programmes, legal routes such as the vetted researcher provisions of the EU Digital Services Act, and data donation by consenting users, each with its own conditions.
Does the lab rate news sources or decide what is true?
No. It studies how information systems work and tests interventions. It does not rate outlets or adjudicate content.
How does the lab handle harmful content in research?
Protocols are designed to minimise exposure, avoid redistributing harmful material and protect the people who study it.
Can a media organisation propose a study?
Yes, by enquiry. Any study proceeds under a published protocol with independent review.
