Our Purpose

The Citizens and Technology (CAT) Lab at Cornell University is a public-interest research group led by Dr. J. Nathan Matias, an assistant professor in the Department of Communication.

Our Mission: Work with communities to study the effects of technology on society and test ideas for changing digital spaces to better serve the public interest.

Our Vision: A world where digital power is guided by evidence and accountable to the public.

How We Work

We do citizen science for the internet. We seek to enable anyone to engage critically with the tech tools and platforms they use, ask questions, and get answers. Working hand-in-hand with diverse communities and organizations around the world, we identify issues of shared concern (“effects”) related to digital discourse, digital rights and consumer protection.

Our research methods can discover if a proposed effect is really happening, uncover the causes behind a systemic issue, and test ideas for creating change.

How do we do this?

Test: Produce scientific evidence on causes and effects, informing how people relate to each other and the digital products that shape our lives.

Discover: Develop research goals with and for the public, growing scientific knowledge by respecting the unique cultures, needs, risks, and potential in every situation.

Empower: Support people worldwide to make discoveries by growing widespread capacity to conduct, interpret, and collaborate on behavioral science at scale.

Innovate: In our quest for citizen behavioral science that is democratic and accountable to the public, we develop open technical, statistical, ethical, and legal systems that anyone can use.

We publish summaries and results of all CAT Lab experiments here on our website. We invite you to explore our research, read our latest news & posts, and sign up for email updates to learn more about what we do and how we do it.

Our Path

The Citizens and Technology Lab (formerly known as CivilServant) began as the MIT PhD project of founder J. Nathan Matias, who was studying the role that anyone can play in understanding digital power and creating change independently from tech firms.

Originally incubated by Global Voices, we have transitioned into Cornell University’s Department of Communication. We are grateful for the support we’ve received from a range of entities, past and present. You can find a complete list of our funders here.
