Ethical research respects human dignity, minimizes harm, ensures informed consent, protects confidentiality, and maintains integrity. Institutional Review Boards (IRBs) evaluate risk-benefit ratios and approve protocols. The APA Ethical Code and Belmont Report provide principles. Misconduct (fabrication, falsification, plagiarism) undermines science. Transparency in methods, data, and analysis supports replicability and accountability.
Review an IRB protocol application. Discuss ethical dilemmas in published studies (e.g., Milgram, Tuskegee) and how modern ethics evolved. Reflect on consent, confidentiality, and data security in your own research design.
You have already studied the empirical research cycle — the process by which scientists pose questions, gather data, and draw conclusions. Ethics is not an external constraint bolted onto that process; it is internal to it. A study that harms participants, obtains consent through coercion, or falsifies data does not just violate rules — it produces corrupted knowledge. The ethical standards governing research exist precisely because the credibility of scientific knowledge depends on the integrity of the processes that produce it.
The Belmont Report (1979), issued in the wake of abuses like the Tuskegee Syphilis Study, articulates three foundational principles. Respect for persons requires treating individuals as autonomous agents capable of making their own decisions — which operationalizes as informed consent. Beneficence means maximizing benefits and minimizing harms — not just avoiding harm, but actively pursuing the participant's welfare. Justice requires the fair distribution of research burdens and benefits across groups — historically disadvantaged populations should not bear disproportionate research risks. These principles are not a checklist; they are often in tension, and the Institutional Review Board (IRB) exists to adjudicate that tension case by case.
The IRB's core function is risk-benefit analysis. Before data collection begins, a protocol describing every procedure, the participant population, consent processes, data storage, and anticipated risks must be submitted and approved. Minimal-risk studies (where risks are no greater than those of daily life) may qualify for expedited review; studies involving vulnerable populations (children, prisoners, pregnant women) or more than minimal risk require full board review. IRBs are not rubber stamps — they can require protocol modifications, impose additional safeguards, or reject proposals. Their oversight is a structural check against the well-documented tendency of researchers to underestimate the risks their own studies pose.
Research misconduct — fabrication (inventing data), falsification (manipulating data), and plagiarism (FFP) — is the most direct form of integrity violation. But subtler forms of misconduct are now equally scrutinized: p-hacking (running analyses until p < .05 appears), HARKing (Hypothesizing After Results are Known), selective reporting of outcomes, and failure to share data or methods. These practices do not involve outright lying, but they distort the literature and undermine replication. The modern emphasis on transparency — pre-registration of hypotheses, open data, open materials, registered reports — is a structural response to these problems. Transparency makes the research process legible to scrutiny, which is the institutional mechanism for catching errors before they propagate into the knowledge base.
