Get Involved
Whether you run a city department, want to spend a year embedded in one, or have evidence to contribute — there is a path for you. The work is only useful if it compounds.
City Partnership
We work with city departments, county agencies, and public authorities to design, run, and report on low-cost randomized pilots. We handle study design, power analysis, randomization, and write-up — your team implements. Practitioner-led, fast-cycle, and designed for city timelines.
Start a conversation →Municipal Fellow
The Municipal Fellows program is designed to place early-career researchers inside city departments for 12 months. Fellows design and run at least one randomized pilot, contribute findings to the Public Registry, and leave a replication-ready protocol behind. The inaugural cohort application will open once initial funding is in place.
Apply for fellowship →Evidence Commons
Practitioners, academics, and policy analysts can submit documented experiments to the Public Registry. We verify sources, assign mechanism tags, and publish findings under a CC-BY license. You retain credit; the city that ran the experiment gets attribution. The field gets cumulative knowledge.
Submit an experiment →Technical Advisor
Statisticians, economists, machine learning researchers, and epidemiologists can join our Technical Advisory Network to help city teams design rigorous experiments, run analyses, and interpret findings. Volunteer advisors are credited on every registry record they contribute to.

We read every message. If you are a city official, researcher, or practitioner with a question that does not fit the form, email hello@experimentsociety.org directly.
Common Questions
How much does a city partnership cost?
Partnerships are structured around the city's capacity. Small pilots (under 2,000 participants) are typically free — we treat them as research investments. Larger, multi-arm trials with dedicated staff time involve a fee that covers analyst time and reporting. We'll be direct about costs in the first call.
Do you work outside the United States?
The Public Registry documents experiments from 22+ countries. The evidence base is international by design — much of the strongest research comes from lower- and middle-income countries where the marginal impact of better evidence is highest. As we build our partnership network, we are actively seeking municipal partners beyond the US.
What if we already ran an experiment but didn't pre-register it?
Submit it anyway. The registry accepts retrospective documentation. We note pre-registration status transparently so readers can weight evidence accordingly. An honest null result from an unregistered trial is still valuable — probably more valuable than it sitting in a filing cabinet.
Are Municipal Fellows paid?
The fellowship is designed to provide a competitive stipend for the 12-month placement, plus health coverage and a research budget. The exact structure will depend on funding secured for each cohort. Host cities would provide desk space and access to administrative data. Fellows would not be city employees — they report to The Experiment Society.
What is the timeline from first contact to running a pilot?
City partnerships are designed to move from first call to randomization in 8–14 weeks, depending on IRB requirements and data access. For common intervention types — benefits outreach, permit simplification, reminder messaging — the design process is straightforward and the ethical review is typically low-burden.
