About Prova · Our purpose

A future worth working toward

A society that can learn how to improve people’s lives.

We want serious inquiry to become an ordinary, accessible part of working for the public good, so more promising ideas can be tried, improved, and built upon.

What could become ordinary

A promising idea gets a fair test.

Competent help is within reach of the people trying to make it work.

What is learned stays useful.

Others can examine the finding, understand its limits, and try it in their own circumstances.

People can build something better.

Knowledge supports new undertakings, cooperation, and the renewal of public institutions.

The purpose, in brief

How today’s work could contribute to a lasting public capability.

People working to improve lives should be able to find out whether their ideas help, how to make them better, and what others have already learned.

That ability changes what is practical to attempt. A small organization can investigate a promising approach. A public agency can adapt a service with a clearer understanding of whom it reaches. A community can question an account of progress that overlooks its experience. Each undertaking can leave the next one better informed.

Building this capacity takes sustained work. Knowledge sits across research, institutional records, and people’s experience. Bringing it together requires expertise, time, and arrangements that let difficult questions be asked. Even an excellent study can arrive too late, remain inaccessible, or lose its meaning as its conclusions travel.

AI opens a significant new possibility. Machines can assist with reading, comparison, reasoning, and the maintenance of knowledge across a scale of material that would otherwise require enormous human attention. Used within carefully designed systems, those capabilities can expand the questions people can afford to investigate and the help experts can provide.

Prova exists to develop that possibility through practical work. Our proprietary evidence systems bring AI into organized, reviewable inquiry, with consequential judgments held by accountable people. Nonprofits and foundations provide a concrete starting point for work whose larger purpose includes government, public agencies, aid, and the institutions through which societies pursue a better life.

The ambition carries responsibilities from the outset. People affected by decisions need a voice in the inquiry. Inconvenient findings need protection. Dignity, rights, and public purposes need standing wherever measurement falls short. Those commitments shape what a useful public capability would have to be.

Over time, serious inquiry could become something people can obtain as a normal part of public work. Prova is a proving ground for that future. Its eventual institutions, ownership, and forms of cooperation are open for others to help shape.

The argument in eight chapters

01 · The possibility

The future we want to help make possible

More people able to try a good idea, learn from it, and leave something others can use.

Consider a neighborhood organization with an idea for helping older residents remain connected to the people around them. Its staff know the local circumstances. Residents have views about what would be useful. There is enough support to begin, but a great deal remains uncertain: who would take part, what would make the activity worthwhile, and whether it would change the isolation the organization hopes to address.

In the future we want, that uncertainty has somewhere to go. The organization can obtain competent help, examine related work, involve residents in the questions, and choose a proportionate way to learn. It can discover that part of the idea needs changing while there is still time to change it. A useful finding can reach another community with enough explanation for people there to judge its relevance.

The same possibility belongs in public administration. A school district considering a different way to support attendance should be able to learn from experience elsewhere and investigate the conditions in its own schools. A public agency changing how it delivers benefits should be able to examine who finds the new process easier and who encounters a new obstacle. Serious questions should have access to serious attention.

More room to attempt something worthwhile

When inquiry is within reach, an idea can develop before its advocates have assembled an expensive case for it. An uncertain beginning can receive patient examination. People can test a practical change, discover why it fell short, and try again with a clearer understanding of the problem. Public work gains a greater capacity for creation as well as correction.

This requires institutions that can respond constructively to what they learn. A result may justify expansion, expose a need for redesign, or suggest that resources would do more good elsewhere. The people responsible for those choices need both an intelligible account and the authority to act on it. Those affected need a way to be heard while the choices are still open.

Learning should also survive the circumstances that produced it. A project ends, staff move on, a government changes. The account of what was tried, why, and under which conditions can remain available. Successors should be able to examine a decision without having to reconstruct its reasoning from the people who happen to remember it.

Across generations, that continuity could widen the range of undertakings societies can sustain. Communities could cooperate around a shared uncertainty. Institutions could revise responsibilities that no longer fit the problem. A new organization could begin with the benefit of earlier attempts, including the unsuccessful ones.

This is a future worth working toward: a greater ability to improve lives through purposeful experimentation, accumulated understanding, and institutions capable of learning. Reaching it requires attention to the conditions that make learning difficult now.

02 · The difficulty

Why learning remains so difficult

Good intentions, useful information, and serious effort can still leave the important question unanswered.

Institutions already learn in many ways. Public servants use research and administrative data. Practitioners notice when a service is failing. Communities explain what an official account has missed. Researchers, evaluators, and independent reviewers produce knowledge that improves public work. The ambition begins with that experience and asks how its benefits can become more widely available.

One obstacle is the cost of bringing the right attention to a question. A record may span years of reports, changing definitions, interviews, spreadsheets, and decisions made by people who have left. Understanding it requires someone to establish what happened and what each source can support. The effort needed to prepare an inquiry can consume the resources that would have paid for a better answer.

Another obstacle is that information is collected for particular purposes. A service record helps staff deliver a service. A grant report accounts for agreed activities. Financial controls establish whether money was spent appropriately. Each has value. Asking whether an undertaking improved people’s lives introduces further questions about outcomes, causes, distribution, and cost.

A record can be complete for its original purpose and insufficient for that later question. An attendance count says who arrived; understanding who could not attend requires a different source. A rise in employment among participants describes a change; estimating the program’s contribution requires a credible account of what would otherwise have happened.

The institutional conditions matter

Even where a question can be answered, the institution may struggle to use the answer. A study can finish after a budget decision. Its findings can cross several departments while responsibility for responding belongs to none. A manager can inherit an indicator whose definition no longer fits the service. These difficulties concern how work is organized as much as how analysis is performed.

Incentives can make the problem harder. A funder may want honest learning while asking each organization to demonstrate success at renewal. A program leader may welcome a better account of results while fearing that uncertainty will be treated as evidence of failure. An evaluator may depend on repeat commissions from the institution whose claims are being examined.

These tensions can arise among people acting carefully within their responsibilities. They call for arrangements that make honest inquiry usable and survivable: questions agreed before results arrive, resources for learning, authority to report inconvenient findings, and decisions that distinguish a weak claim from the worth of the people doing the work.

Some disagreements persist after the facts are clear. An institution can know that a change would help and still lack the authority, money, or political support to make it. People can agree about an effect and disagree about whether its costs are acceptable. Evidence must enter those decisions without pretending to settle every consideration within them.

The practical task is therefore larger than commissioning another study. It includes making inquiry affordable, connecting it to responsibilities and timing, and preserving room for findings that change the expected account. That is the setting in which new technical capabilities become consequential.

03 · The opening

What is becoming possible

Machines can now do useful work with language, reasoning, and memory. That changes what people can undertake.

There is something remarkable in being able to ask a machine to read a body of work, compare accounts within it, reason through a question, and return to relevant material as the inquiry develops. Tasks that once depended entirely on a person’s available attention can now receive substantial machine assistance.

These capabilities reach material that institutions have often struggled to use fully: reports that need to be read together, open responses that need careful examination, a change in policy buried among successive versions, or research scattered across unfamiliar fields. A model can help identify patterns, propose explanations, and expose a question that deserves closer investigation.

The significance extends beyond producing the same report more quickly. When the effort required to explore a question falls, more questions become practical to pursue. A small organization can consider inquiry earlier. An expert can enter a discussion with more of the background already assembled. A promising idea can receive attention before a large research budget exists.

Attention can reach further

Imagine a public agency preparing to change a service that several other jurisdictions have already tried to improve. The relevant knowledge might include evaluations, implementation notes, public consultations, and accounts of changes abandoned along the way. AI can assist with finding and comparing that material, connecting statements to sources, and identifying differences requiring professional attention.

The expert’s work can then concentrate more fully on what matters locally: which comparisons deserve weight, what the agency can deliver, whose experience is missing, and which uncertainty could change the decision. Better preparation can also reveal that existing knowledge is sufficient, or that a proposed study would answer the wrong question.

This opening reaches the design of new inquiry too. Systems can assist with reviewing instruments, drafting research materials, checking consistency, and maintaining the record as a project changes. Savings in that supporting work can make a stronger design feasible. The actual gain depends on the task, the quality of the material, and the work required to check the output.

Dependability has to be built

A model can miss a decisive passage, misread a table, or produce an explanation unsupported by its sources. Its fluency can make those errors difficult to notice. Access to a large volume of text is a capacity to examine it; dependable coverage requires deliberate checks. Research on long contexts has shown why the placement of relevant material can matter to retrieval.

Useful machine reasoning therefore belongs within work that can be inspected and challenged. Sources need to remain accessible. Important statements need checking. The question and the limits of the record need to stay visible as the work develops. People must retain authority to reject the proposed explanation and pursue another one.

We see a substantial opportunity in building those conditions around expanding model capabilities. Greater access to inquiry can give people more room to create, adapt, and learn together. The next chapter concerns the standards that let that opportunity become useful knowledge.

A closer lookWhat it means for a system to remember

A useful institutional memory preserves the basis of an answer: the question, the material examined, the interpretation, the uncertainty, and what later changed. A summary alone can lose precisely the qualification a future reader needs.

Maintaining that memory requires identified sources, preserved versions, appropriate access, and someone responsible for updates. When a finding changes, the earlier account should remain understandable alongside the revision. When information becomes outdated, the system should help people see that its usefulness needs reconsideration.

Models can help retrieve, compare, and update such a record. The surrounding arrangements make it possible to rely on what is remembered and to correct it when necessary.

Research on capability and limits: retrieval-assisted literature synthesis and language models’ use of long contexts. These studies examine particular systems and tasks.

For how Prova uses these capabilities in practice, see Prova AI.

04 · The discipline

What it takes to learn honestly

Confidence comes from how the question is answered, with the reasoning and its boundaries available for inspection.

A useful inquiry starts by identifying what someone needs to understand. Whether a service reaches the intended people, why implementation varies, how participants experience it, and whether it causes an improvement are distinct questions. They can require different evidence and lead to different decisions.

Existing research may answer part of the question. Administrative records may describe delivery. Interviews may reveal a barrier no standard measure captures. A new study may be warranted where an important uncertainty remains. The method follows the question, the circumstances, and the strength of the conclusion the decision requires.

Causal questions need particular care. To estimate a program’s effect, an inquiry must establish a defensible comparison with what would have happened without it. Random assignment can provide that comparison in appropriate settings. Other designs use variation in eligibility, timing, or circumstances, each with assumptions that need examination. A model’s prediction acquires causal meaning only through a justified design and assumptions.

Technical sophistication cannot restore information that was never recorded or remove uncertainty merely by redescribing it. Sometimes the responsible conclusion is that a proposed question cannot be answered well enough from the available material. That conclusion can still guide a decision about what to say now, what to change, or what would be worth learning next.

Worked exampleA service improves. What can we conclude?

Consider an illustrative employment program. Its follow-up records show a higher employment rate among the participants observed at the end of the year than at enrollment.

The observed result

Employment increased among the participants included in the follow-up record.

That statement needs its denominator, period, and missing follow-up made clear. It tells an institution something useful about the people observed.

The further question

How much of the increase occurred because of the program?

The local labor market may have improved. People who enrolled may differ from those who did not. A credible effect estimate must address those alternatives through its comparison and design. An elaborately modeled projection still needs its assumptions justified.

The institution may decide to continue the service while seeking a stronger answer. That judgment can consider demand, delivery, cost, participant experience, and the consequences of interruption. Its public account should distinguish the observed result from the reasons for continuing.

Knowledge accumulates with its boundaries

Learning that an approach helped in one setting creates a further question about where else it might help. Staffing, institutions, local knowledge, the people involved, and the surrounding services can affect what happens. The conditions of a successful study belong in the account that travels with it.

As people examine a finding across settings, they can develop a richer understanding of the circumstances in which it holds. A difference between two studies can become useful evidence about implementation or context. Keeping those differences visible gives future inquiry more to build on than a list of favored interventions.

Qualitative and quantitative work each contribute to this understanding. An estimate can describe a pattern that interviews help explain. Experience can identify an outcome missing from the instrument. A careful inquiry makes clear what each form of evidence contributes and where professional interpretations differ.

Systems that support demanding work

Prova’s proprietary evidence systems organize inquiry around questions, claims, sources, and decisions. They direct AI-assisted work, preserve connections to the record, and make gaps, conflicts, and unresolved questions visible for review. Experts can examine the reasoning, challenge assumptions, and keep uncertainty present through the conclusion.

Named people remain responsible for consequential judgment. They must understand the context, consider alternatives, and explain why the evidence supports the conclusion reached. A reader should be able to distinguish what was observed, what was inferred, and what the responsible institution decided to do.

Cheaper inquiry can extend this discipline to more of public life. The same opportunity makes persuasive but poorly supported conclusions easier to produce. Source connections, independent challenge where needed, and accountable interpretation become more valuable as the volume of analysis grows.

05 · The foundations

What must be protected

Greater capacity to investigate brings greater responsibility for whose purposes inquiry serves.

The ability to ask more questions gives institutions more power over the people described in their records. Used well, it can reveal exclusion, correct an unfair account, and help a service respond to experience it previously overlooked. Its legitimacy depends on the terms under which that knowledge is sought and used.

Three commitments have equal standing in the future we want to help build. Each can change the question, the design of the inquiry, and what may responsibly be done with the answer.

Foundation 01

The people affected have a voice.

People living with a decision should be able to help shape what is asked, measured, and understood. Their experience can reveal a purpose the institution has defined too narrowly, an obstacle its records conceal, or a consequence its preferred outcome leaves out.

Meaningful participation begins while choices remain open. It requires accessible ways to contribute, clarity about how contributions will be used, and a route to challenge an account that misrepresents experience. Those responsibilities continue when the findings are interpreted and decisions are made.

In practiceA community is repeatedly asked to provide information about a service. The inquiry should address questions people there consider useful and return an intelligible account of what was learned, with an opportunity to contest it.

Foundation 02

Inconvenient inquiry is protected.

Questions need room to produce answers that a funder, provider, public official, or evaluator would prefer to avoid. Credibility depends on who controls the question, the record, the interpretation, and the ability to communicate an adverse or inconclusive finding.

Independence has to be arranged around the work. Payment tied to a favorable result creates one kind of pressure. Reviewing work one helped produce creates another. These relationships need explicit treatment, with separation and external scrutiny where the judgment requires them.

In practiceA foundation pays for an organization to examine its work. Funding that help should give the organization the agreed space to learn. Access to its private learning record requires its own clear basis and permission.

Foundation 03

Dignity and public purpose retain their standing.

Measurement gives some aspects of life greater visibility than others. A service may offer continuity, belonging, or a place to be heard while performing poorly against a narrow administrative measure. That discrepancy should prompt an examination of both the service and the adequacy of the measure.

Rights and dignity constrain what may be done in pursuit of an outcome. A favorable average cannot by itself justify an intrusion, explain away an unequal burden, or settle which public purposes deserve priority. Those judgments need to remain explicit and open to the people entitled to make them.

In practiceA measure rewards rapid placement into work. The inquiry also needs to examine whether the work is safe, sustainable, and compatible with the responsibilities participants carry. Speed alone gives an incomplete account.

Affordability includes the burden on people

Analysis can become less expensive while the demands placed on everyone else increase. Another survey still takes time. Linking records can create new exposure. A request that seems modest in one project may be the latest in a series of requests to the same household or frontline team.

The cost of inquiry should therefore include the time, disruption, and risk borne by those who provide its information. Existing material should be used where appropriate, new collection should have a clear purpose, and the value of another answer should justify what obtaining it asks of people.

Governance and authorityWho gets to define credible evidence?

Standards decide which claims receive attention and which forms of experience count. The people setting them exercise power, including when they act with methodological care.

A legitimate arrangement makes its standards and their reasons open to examination. It preserves disagreement, allows errors to be challenged, and provides a way to revise a rule that repeatedly excludes relevant knowledge. Different professional judgments should be visible where they could change the conclusion.

These obligations apply to Prova as fully as to any institution using its work. A commercial interest in an answer, a method, or the success of the firm belongs within the inquiry into credibility.

For the arrangements around current work, see Independent Review and Security & Data Practices.

06 · The larger ambition

From individual projects to a shared public capability

What one institution learns can become part of what others are able to do.

Imagine that a public servant with a consequential question could obtain competent evidence support as an ordinary part of the job. The help would begin with the decision and the available knowledge. It could draw on local experience, relevant research, administrative material, and specialists where the question required them. Its scale would fit the stakes.

Now imagine that the account remained useful afterward. A successor could understand why a choice was made. Another institution could examine the approach. A community could challenge a public claim. With appropriate permissions and protections, a finding could travel with enough of its context to support further inquiry.

Together, those capabilities would change the starting conditions of public work. An institution would have access to help in the present and a usable inheritance from work already undertaken. Each new project could contribute to that inheritance.

What a useful account can carry forward

The purpose and question

What people hoped to improve, and what they needed to understand.

The finding and its conditions

What was learned, for whom, where, and with what uncertainty.

The judgment and responsibility

Who interpreted the evidence, who decided, and the reasons for acting.

The next inquiry

What changed afterward and which questions remain worth pursuing.

What travels depends on permission and purpose. Shared learning can preserve useful knowledge while protecting personal and confidential records.

A stronger basis for cooperation

Organizations do not have to agree on an entire strategy to investigate a question together. A public agency, a nonprofit, and a community group might begin with a common concern about who is being missed by a service. They could agree on how to examine it, preserve their different interpretations, and use the findings to identify a practical next step.

That kind of cooperation could make new undertakings possible. Partners could establish what they need to learn before committing to a permanent institution. Several funders could support inquiry whose value extends beyond any one portfolio. Public bodies could reconsider a division of responsibilities when evidence shows that the problem crosses the boundaries within which they operate.

Institutional renewal would still require authority, resources, public deliberation, and choices about competing purposes. Better knowledge gives those processes more to work with. It can clarify a disagreement, reveal an assumption that no longer holds, or show that a proposed arrangement deserves a fair trial.

Learning that moves in more than one direction

The ambition extends across countries and communities. India and countries beyond the OECD belong within it as contributors of methods, experience, and institutional invention. Knowledge should be able to move in several directions, with local professionals and communities examining what another setting’s findings mean for their own.

Translation involves more than language. A practice can depend on relationships, public authority, working conditions, or a form of trust that a report barely mentions. Reciprocal learning takes those differences seriously and gives the people receiving an idea a role in judging and adapting it.

Public infrastructure can take several forms

A capability this widely available could be supported by public agencies, independent institutions, professional networks, universities, commercial providers, or combinations of them. Its durability would depend on access, financing, standards, maintenance, and governance. Which functions belong together and who should own them are questions to work through.

Prova’s contribution begins with practical work that can help establish what such a capability requires. Real questions expose where assistance is useful, where expertise remains essential, and what can responsibly be carried from one setting to another. That is how a firm working today can contribute to a future extending far beyond itself.

07 · The undertaking

Why Prova, and why I am building it

A conviction formed through consequential work, and a new ability to act on it.

For more than fifteen years, my work has sat close to consequential decisions in capital markets, philanthropy, and government. Senior leaders are surrounded by information. They need to know what deserves weight, what can withstand scrutiny, and what must remain unresolved. The quality of a decision depends on making those distinctions clearly.

Capital-markets work taught me to pay attention to the coherence of an institution’s account: what it says it is doing, what its choices reveal, and whether its claims remain credible under pressure. Sustained investor engagement with large multinationals, and advising a global financial institution’s India leadership during the 2008 financial crisis, required disciplined preparation and language executives could stand behind.

Building an advisory firm and working across corporate philanthropy and social programs changed the substance of the questions. Public health, education, road safety, homelessness, pandemic response, and economic mobility each carried a different definition of success and different consequences for getting it wrong. The work made the relationship between an institution’s intentions, its implementation, and its account of results impossible to treat casually.

I learned how much the information an organization produces is shaped by its incentives, governance, operating constraints, and the decisions its leaders expect to make. A report can accurately describe activity while leaving the purpose of that activity unresolved. An evaluation can answer an important question and still arrive in a form, or at a time, that makes it difficult to use.

Government brought those lessons into cabinet-level policy and long-term economic planning. Analysis sometimes had months to mature and sometimes twenty-four hours. In either case, it had to connect policy intent, ministerial responsibility, implementation, and measurement in a form senior decision-makers could use. A method had to remain coherent under scrutiny and time pressure.

What became possible to build

That experience shaped the approach behind Prova. Questions need to be connected to the decisions they inform. Assumptions, sources, claims, and limits need to be explicit. People with responsibility need an account they can examine, challenge, and carry into action.

AI changed what I could undertake myself. I could use the available capabilities to develop the systems and build the organization through which to pursue this work. The same change that opened new possibilities for inquiry also expanded my ability to create a firm around them.

That brought a personal responsibility into focus. Work I had reason to care about had become practical for me to attempt. I wanted to use that opening in service of people whose lives depend on institutions making thoughtful, informed choices.

Prova gives that conviction a concrete form. Work with nonprofits and foundations brings the systems into questions where purpose, limited resources, professional judgment, and the experience of people being served meet directly. It also provides a setting in which to improve the approach and learn what can be useful more widely.

Ravi Narain

Prova’s systems are built, and the firm is accepting engagements.

Examining the contributionWhat would make this work valuable?

Prova’s contribution should be examined through the quality and usefulness of its work. Relevant questions include whether an inquiry arrives in time, whether its conclusions withstand review, whether it helps people understand a consequential choice, and what obtaining that help costs everyone involved.

The examination should also ask whether useful methods travel beyond the circumstances in which they were developed. A result dependent on one person, an unusually complete record, or a narrow class of questions needs to be understood on those terms.

Independent scrutiny belongs in this account. Comparisons should have defined tasks and standards, costs should include review and correction, and inconvenient findings about Prova’s own work should remain visible. These are criteria for examining the contribution as it develops.

08 · The invitation

A future others can help shape

The purpose creates room for many kinds of contribution.

The future described here would be built by people working in many different settings: public servants, practitioners, researchers, communities, funders, and people creating institutions that do not yet exist. Each brings knowledge and responsibilities that the others cannot supply alone.

Making inquiry affordable is one part of that work. Making it trustworthy and useful is another. Keeping it available through changes of leadership, protecting room for disagreement, and ensuring that people can build on what is learned require sustained institutional effort.

We want Prova to contribute to those conditions through work people can examine and use. The questions encountered in practice should improve the systems, sharpen the methods, and inform the larger ambition. Others may find better approaches, identify consequences we have overlooked, or build complementary and independent versions of the capability.

That openness matters to the purpose. A public capability gains value when people can contribute to it, question its standards, and carry useful knowledge into circumstances its originators never anticipated. Its future should remain responsive to what those people learn and choose.

If this is work you want to follow, support, participate in, or challenge, we welcome a conversation. You may bring a practical question, methodological experience, an institutional opportunity, or a different account of what society needs. Each can help give the ambition a more useful form.

We begin with a possibility worth pursuing: that people trying to improve lives could have much greater access to the knowledge and help their work deserves, and leave more behind for those who follow them.
