Scientific Research: Frequently Asked Questions

Scientific research spans every organized effort to generate, test, and validate knowledge about the natural world — from bench-scale laboratory experiments in molecular biology to multi-decade observational studies in astrophysics. This page addresses the questions most commonly raised about how scientific research is defined, classified, regulated, and evaluated, with reference to the standards bodies and federal agencies that govern it in the United States. The scope covers both basic and applied research contexts, the institutional frameworks that shape them, and the procedural boundaries that determine when formal oversight applies.

What does this actually cover?

Scientific research, as formally defined by the federal government, encompasses systematic investigation designed to develop or contribute to generalizable knowledge. The home resource on this domain provides broader orientation to the physics and quantum science context within which much of this material is framed, but the questions addressed here apply across the full spectrum of natural and physical sciences.

The National Science Foundation (NSF) and the National Institutes of Health (NIH) represent the two largest federal funding bodies for US scientific research, collectively disbursing over $50 billion annually in research grants, contracts, and cooperative agreements (NSF Budget, NIH Appropriations). Research activity is typically segmented into three federally recognized categories:

1. Basic research — experimental or theoretical work undertaken primarily to acquire new knowledge without immediate application in view.
2. Applied research — original investigation directed toward a specific practical aim or objective.
3. Experimental development — systematic work drawing on existing knowledge to produce new materials, products, or processes.

These distinctions align with the OECD Frascati Manual definitions adopted by the NSF's National Center for Science and Engineering Statistics (NCSES) for standardized reporting across institutions.

What are the most common issues encountered?

Research teams operating within academic, governmental, and private-sector settings encounter a recurring set of challenges tied to funding cycles, data integrity requirements, and compliance obligations.

Reproducibility is one of the most documented structural problems. A 2016 survey published in Nature found that more than 70% of researchers had tried and failed to reproduce another scientist's experiments, and more than 50% had failed to reproduce their own. This reproducibility gap has prompted formal responses from the NIH, including the 2014 Principles and Guidelines for Reporting Preclinical Research.

Research misconduct — defined by federal regulations at 42 CFR Part 93 to include fabrication, falsification, and plagiarism — triggers mandatory institutional review and potential debarment from federal funding. The Office of Research Integrity (ORI) at the Department of Health and Human Services oversees compliance in NIH-funded research.

Conflict of interest disclosures represent a third persistent issue. NSF and NIH both require investigators to disclose significant financial interests above defined thresholds — NIH sets the reporting threshold at $5,000 in financial interests from a single entity related to the researcher's institutional responsibilities (42 CFR Part 50, Subpart F).

How does classification work in practice?

Classification of research activities follows a layered logic that determines funding eligibility, regulatory requirements, and ethical oversight obligations.

At the federal level, the primary classification axis separates federally funded from privately funded research, since federal involvement triggers specific compliance frameworks that do not apply automatically to privately financed work.

Within federally funded research, classification proceeds by:

1. Discipline — as organized by NSF into seven broad research directorates including Biological Sciences, Computer and Information Science and Engineering, and Mathematical and Physical Sciences.
2. Research involving human subjects — governed by the Federal Policy for the Protection of Human Subjects, codified at 45 CFR Part 46 and commonly called the "Common Rule," which classifies research protocols by risk level into exempt, expedited, or full-board review categories.
3. Research involving animal subjects — classified under the Public Health Service Act and the Animal Welfare Act, with oversight delegated to Institutional Animal Care and Use Committees (IACUCs).
4. Dual-use research of concern (DURC) — a specialized classification applied to life sciences research that could be misused to pose a threat to public health or biosecurity, governed by a 2012 US Government Policy (Office of Science and Technology Policy).

The key contrast in this system is between exempt and non-exempt human subjects research. Exempt classifications relieve investigators from ongoing IRB oversight but do not eliminate the initial determination requirement — an institution, not an individual investigator, makes the exemption determination.

What is typically involved in the process?

A standard research project in an academic or federally funded setting moves through identifiable phases, each with associated procedural requirements.

Phase 1 — Proposal and funding application. Investigators submit proposals responding to formal funding opportunity announcements (FOAs). NSF uses a merit review system evaluating Intellectual Merit and Broader Impacts; NIH uses a scoring system on a 1–9 scale, with scores at or below 20 (on a percentile basis) generally considered competitive for most institutes.

Phase 2 — Regulatory and ethical clearances. Before data collection begins, projects involving human subjects require IRB approval, those involving vertebrate animals require IACUC approval, and projects touching select agents or recombinant DNA require institutional biosafety committee (IBC) review.

Phase 3 — Data collection and management. NIH's 2023 Data Management and Sharing Policy requires investigators to submit a Data Management and Sharing Plan (DMSP) with all new funding applications, specifying how scientific data will be preserved and made accessible (NOT-OD-21-013).

Phase 4 — Analysis and reporting. Results are subject to peer review through journal submission. Federal grantees must submit annual progress reports and final project reports through agency-specific systems (NSF's Research.gov; NIH's eRA Commons).

Phase 5 — Post-award compliance. Financial reporting, equipment inventories, and patent disclosure obligations under the Bayh-Dole Act (35 U.S.C. §§ 200–212) apply to any invention arising from federally funded research.

What are the most common misconceptions?

Misconception 1: Peer review certifies that findings are correct. Peer review is a quality screening process, not a verification of truth. Reviewers assess methodology, logic, and presentation — they do not independently replicate the experiments. The ORI and the Committee on Publication Ethics (COPE) both document cases where peer-reviewed articles contained fabricated data that passed initial review.

Misconception 2: Basic research has no practical regulatory implications. Basic research can still require full IRB oversight, biosafety committee approval, and export control compliance under the Export Administration Regulations (EAR) administered by the Bureau of Industry and Security (BIS). Fundamental research exclusions under National Security Decision Directive 189 (NSDD-189) narrow but do not eliminate these obligations.

Misconception 3: Institutional review board (IRB) approval applies to all types of research. IRB oversight under 45 CFR Part 46 applies specifically to research involving human subjects. Quality improvement projects, public health practice, and program evaluations may not meet the regulatory definition of "research" and therefore fall outside IRB jurisdiction — though the distinction must be formally evaluated, not assumed.

Misconception 4: A non-significant p-value means no effect exists. A p-value above the conventional 0.05 threshold indicates insufficient statistical evidence to reject the null hypothesis under the study's design — not proof of absence of effect. The American Statistical Association issued a formal statement in 2016 cautioning against binary interpretations of statistical significance.

How do requirements vary by jurisdiction or context?

Requirements governing scientific research vary substantially across 4 primary axes: federal versus state jurisdiction, domestic versus international scope, institutional type, and funding source.

Federal versus state. Federal regulations establish floor-level standards for research involving human subjects, animal welfare, and biosafety. States may impose additional requirements — California's Health and Safety Code, for example, imposes state-level oversight of stem cell research through the California Institute for Regenerative Medicine (CIRM), which operates independently of NIH funding criteria.

International research. US investigators conducting research abroad must comply with both US federal regulations and the host country's ethical and legal requirements. The NIH Fogarty International Center provides guidance, but there is no single harmonized global standard. The Declaration of Helsinki (World Medical Association) establishes widely referenced ethical principles for medical research involving human subjects, though it carries no binding legal force in US courts.

Institutional type. Research conducted at institutions holding a Federalwide Assurance (FWA) from OHRP is bound by the Common Rule for all research, regardless of funding source, if the institution has adopted an expanded assurance. Institutions without expanded assurances are bound only for federally funded research.

Funding source. Department of Defense (DoD)-funded human subjects research is governed by a separate regulation at 32 CFR Part 219, which mirrors but is distinct from HHS's 45 CFR Part 46. Defense-funded research also implicates DoD Instruction 3216.02 for additional protections.

What triggers a formal review or action?

Formal review or enforcement action in scientific research contexts is triggered by defined threshold events, not discretionary assessments.

Research misconduct allegations. Under 42 CFR Part 93, any allegation of fabrication, falsification, or plagiarism in PHS-funded research requires institutions to complete an initial inquiry within 60 calendar days of receiving the allegation. If the inquiry finds sufficient evidence, a full investigation must be completed within 120 days. ORI receives institutional investigation reports and conducts independent oversight review.

Unanticipated problems involving risks to subjects or others (UPIRSOs). Under OHRP guidance, any unanticipated problem that involves unexpected risk to research subjects or others must be reported promptly to the IRB, the institution, and OHRP. Failure to report is treated as a compliance violation that can result in suspension of an institution's FWA.

Financial irregularities. NSF's Office of Inspector General (OIG) and NIH's OIG both conduct audits and investigations of grant expenditures. Disallowed costs or unsupported charges detected during audit trigger formal findings and may result in fund recovery demands or debarment.

Export control violations. Transfers of controlled research materials, data, or technology to foreign nationals — including on-campus laboratory access — may constitute a "deemed export" requiring a license under EAR or the International Traffic in Arms Regulations (ITAR), administered by the State Department's Directorate of Defense Trade Controls (DDTC). Violations can result in civil penalties up to $1,000,000 per violation under ITAR (22 CFR Part 127).
