Examples of Joint Fact-Finding in Practice - Compiled by Claude (AI)

Claude Query:

April 14, 2026 —To include in an article that I am writing about your answer to our common ground query on immigration, I would like to include (for people unfamiliar with the term joint fact-finding) quick summaries of past joint fact-finding efforts that illustrate the kind of things that could be done. While it would be nice to have examples directly focused on immigration, I recognize that these may not exist and that we may need to rely on examples from other joint fact-finding efforts -- efforts which may date back to the 1980s  and 1990s when the use of this technique is more widespread (and before US society became so hyperpolarized and distrustful). Can you find me 3 to 5 examples with links the people to follow for more information?

Claude Response: Examples of Joint Fact-Finding in Practice

The following five examples illustrate what joint fact-finding looks like in practice. None deal directly with immigration, but they span the 1980s through early 2000s — when the technique was most widely used — and the general principles transfer well across issue areas.

1. The New York Bight Initiative (1987–1996)

The problem: Severe pollution of the waters off New York and New Jersey — including PCB contamination, medical waste washing up on beaches, and collapsing fisheries — had produced a standoff between chemical manufacturers, environmental groups, government agencies, and public health advocates who could not agree on the basic facts, let alone solutions.

What they did: The New York Academy of Sciences convened 22 stakeholder groups — ranging from Clean Ocean Action to the Chemical Manufacturers Association — for a series of ten mediated sessions facilitated by a neutral professional. Scientists from Woods Hole, Texas A&M, and local universities were brought in not to advocate, but to share expertise. One of the key early breakthroughs was developing agreed-upon definitions of technical terms, which allowed non-scientists to participate as equals. The process ultimately produced consensus on 26 management recommendations and a signed agreement among 18 participating organizations. This is perhaps the most-cited case study in the academic literature on joint fact-finding, and it became a template for subsequent efforts.

2. The National Acid Precipitation Assessment Program — NAPAP (1980–1990)

The problem: In the early 1980s, acid rain was one of the most bitterly contested environmental issues in America. Some scientists and advocates called it a rapidly intensifying ecological disaster; industry-aligned voices dismissed it as a speculative hypothesis. Congress and the Reagan administration were at an impasse, with no shared factual foundation for policy.

What they did: Congress authorized a massive, decade-long, multiagency joint fact-finding program coordinated by an Interagency Task Force representing 12 federal agencies (EPA, NOAA, the Department of Energy, Agriculture, Interior, NASA, and others). When NAPAP was initiated in 1981, scientific opinion on acid rain was sharply divided between those who saw it as an imminent catastrophe and those who dismissed it as speculation. By the time the assessment concluded in 1990, most scientific opinion had moved well inside both of those extreme positions. That shared factual foundation made possible the landmark acid rain provisions of the 1990 Clean Air Act Amendments.

3. The CALFED Bay-Delta Program (1994–2009)

The problem: California’s water wars — pitting farmers, urban water authorities, environmentalists, and the federal government against each other in endless litigation over the Sacramento-San Joaquin Delta — had become ungovernable. After a six-year drought made the crisis acute, all parties recognized that the courtroom battles were producing no solutions.

What they did: In 1994, CALFED brought together federal and state agencies, environmentalists, agricultural interests, and urban water users around a shared commitment to evidence-based problem-solving rather than litigation. The resulting Bay-Delta Accord created a joint federal-state program with shared scientific panels, independent review processes, and a structure for bringing contending parties around a common body of evidence on water quality, ecosystem health, and supply reliability. CALFED is also a useful cautionary tale: the program ultimately faltered when political will waned and funding dried up — a reminder that joint fact-finding must be sustained over time to be effective.

4. EPA Negotiated Rulemaking — “Reg-Neg” (1980s–1990s)

The problem: Federal rulemaking had become so adversarial that regulations often took years to finalize and were routinely challenged in court the moment they were issued, even when the underlying facts were not seriously in dispute. Parties withheld information strategically and took extreme positions rather than engaging constructively with evidence.

What they did: In 1982, administrative law expert Philip Harter proposed face-to-face negotiation among affected parties as a remedy for the dysfunction that had come to characterize federal rulemaking. The EPA and the Department of Transportation were the first agencies to experiment with the approach. In one early and well-documented success, EPA’s wood-stove emission standards went into effect roughly two years earlier than expected, benefiting both environmentalists (who gained faster coverage of over 1.5 million stoves) and manufacturers (who gained regulatory certainty sooner). Congress formally endorsed the approach in the Negotiated Rulemaking Act of 1990. While the method’s track record is mixed, its best successes came when factual disputes were disentangled from value disputes early in the process.

5. The Altamont Pass Wind Energy Joint Fact-Finding (California, early 2000s)

The problem: One of the nation’s first and largest wind farms, in California’s Altamont Pass, was killing large numbers of raptors and other birds — but the science was deeply contested. Wind energy companies, environmental groups, wildlife agencies, and bird conservation organizations each had different data, different interpretations, and strong incentives to dispute each other’s findings.

What they did: A structured joint fact-finding process brought all the contending parties together around a Scientific Review Committee, charged specifically with building shared understanding of the facts before any policy decisions were made. The committee successfully fulfilled its scientific charge, reaching genuine consensus among parties that had previously been unable to agree on even basic empirical questions. The Altamont case is also a valuable illustration of the limits of joint fact-finding: consensus on facts does not automatically produce consensus on policy when underlying value differences remain unresolved.
