The question

Mapping source visibility and information diversity in AI answers

The AI Pluralism Monitor is a research project of the Media and Journalism Research Center (MJRC) that investigates how artificial intelligence systems present news, public affairs and media sources to users.

As millions of people begin to use AI assistants, answer engines and search-integrated chatbots to ask about politics, current affairs, media ownership and public institutions, AI systems are becoming new intermediaries between citizens and the news.

These systems do not browse the news like humans do. They select, summarise, rank, recommend and sometimes omit sources before users ever reach the original journalism.

When people ask AI systems about news and public affairs, which media sources become visible, trusted, cited, distorted or erased?

Visibility

AI visibility

Which media outlets appear in AI-generated answers, and how often?

Attribution

Source attribution

Do AI systems cite sources clearly, link to original journalism, or provide answers without auditable evidence?

Risk

Pluralism risk

Do AI systems over-rely on dominant, state-aligned, captured, foreign or platform-optimised sources?

Why this matters

Why this project matters

The public debate about AI and journalism has so far focused heavily on copyright, licensing, newsroom automation and the use of generative AI in content production. These issues are important. But another transformation is already taking place: AI systems are becoming intermediaries between citizens and the news.

When a user asks an AI system what is happening in a country, which outlets are reliable, who owns the main television channels, or whether public media are independent, the answer may shape how that user understands the information environment.

The system may cite a narrow group of dominant outlets, rely on international sources instead of local journalism, ignore investigative or minority-language media, amplify state-aligned sources, or provide confident answers without transparent attribution.

For media pluralism, this creates a new research challenge. It is no longer enough to ask who owns media outlets, who funds journalism, or which platforms distribute news. We also need to ask which sources AI systems make visible and which ones they leave out.

The core claim of the project is careful but important: In structured tests, AI systems make some sources highly visible and others nearly invisible. This has consequences for media pluralism, journalism sustainability and the public’s right to access diverse information.
Research dimensions

What the project studies

The AI Pluralism Monitor tests how major AI systems respond to structured questions about national news ecosystems. The project examines whether AI answers are accurate, properly sourced, pluralistic and transparent. The research focuses on several dimensions.

01

AI visibility

Which media outlets appear in AI-generated answers, and how often.

02

Source concentration

Whether answers repeatedly rely on a small number of dominant outlets.

03

Independent journalism

Whether investigative, non-profit, local and public-interest media are visible in AI responses.

04

Local and minority-language media

Whether AI systems surface local, regional, community and minority-language sources when relevant.

05

State and captured media risk

Whether state-controlled, politically influenced or captured outlets are amplified disproportionately.

06

Accuracy and distortion

Whether AI systems hallucinate, misattribute, overstate certainty or flatten contested issues.

A growing database

Countries and database expansion

The AI Pluralism Monitor is designed as a growing country database. The first phase focuses on ten countries selected to capture variation in language, media-system structure, market size, platform dependence, political environment and media-capture risk.

The database is then expanded over time to include additional countries, regions and language environments. This allows the project to track not only how AI systems treat individual national media ecosystems, but also how patterns of source visibility and information diversity compare across countries.

The first group of countries combines European and non-European cases, large and medium-sized media markets, English and non-English environments, EU and non-EU countries, and contexts with different levels of media freedom, public-service media strength and political pressure.

Systems under test

AI systems tested

The project tests a set of major AI systems, including ChatGPT, Gemini, Copilot, Perplexity, Claude, DeepSeek, Meta AI, Grok and Google AI Overviews/Search, where available.

These systems are selected because they represent different forms of AI-mediated information access: general-purpose chatbots, search-integrated assistants, AI answer engines, social-platform-integrated systems and search engine AI summaries. Additional country-relevant systems are added where they are widely used or particularly important to the local information ecosystem.

Chatbot

ChatGPT

General-purpose chatbot; search-integrated when web mode is used.

Search AI

Gemini

Search-integrated AI assistant.

Search AI

Copilot

Search-integrated AI assistant connected to the Microsoft ecosystem.

Search layer

Google AI Overviews/Search

Search engine AI summary layer, where available.

How it works

Methodology

For each country, MJRC builds a verified baseline list of relevant media sources, including national news outlets, public-service and state media, television and radio brands, digital-native outlets, local and regional media, investigative and non-profit outlets, minority-language or community sources, and politically aligned or state-influenced media where relevant.

Researchers then use a standard prompt bank to ask each AI system comparable questions in English and in the main local language. The prompts cover current news, reliable source recommendations, media ownership, public media, local and minority-language media, political influence, corruption, elections and media freedom.

Each response is archived with the full prompt, system name, date and time, language, links, citations, screenshots where needed, and information on whether browsing or search mode was active.

The project then codes every response for the sources cited, mentioned or recommended; the accuracy of the information provided; the transparency of attribution; the type of sources used; and the diversity of the media ecosystem represented.

How we work

Research principles

The project does not start from the assumption that AI systems are biased against particular outlets, countries or political positions. Instead, it uses structured testing to document patterns of visibility, omission, concentration, distortion and attribution.

The project distinguishes between sources that are not cited, sources that are misrepresented, and sources that are systematically made more visible than others.

It also separates factual accuracy from pluralism, because an AI answer can be factually correct while still relying on a narrow or unrepresentative source base.

The project publishes its methodology, prompt bank and coding framework so that its findings can be scrutinised, replicated and expanded.

About MJRC

The Media and Journalism Research Center (MJRC) is an independent research organisation that studies media ownership, funding, regulation, journalism, technology and power.

The AI Pluralism Monitor extends this work into the AI era by examining how machine-mediated information systems influence the visibility, ranking and interpretation of journalism.

Mapping the information infrastructure behind AI answers

The AI Pluralism Monitor asks not only what AI systems say about the news, but whose journalism they make visible when they say it.
