Research ethics & IRB

Every ugly chapter in research history — Tuskegee, Nazi experiments, Milgram's shocks — birthed the safeguards you now have to know. The watchdog is the Institutional Review Board (IRB): a committee that reviews proposed studies before they begin to protect human participants from harm.

At the heart sits informed consent. Participants must be told the study's purpose, procedures, foreseeable risks and benefits, that participation is voluntary, and that they may withdraw at any time without penalty. Consent must be given by someone competent to understand it — free of coercion. Deception is tightly restricted: it's permitted only when the study can't be done otherwise, the risk is minimal, and it's justified by scientific value — and then researchers must debrief participants afterward, explaining the true nature of the study. Confidentiality and, ideally, anonymity protect participant data.

Some groups get extra protection as vulnerable populations — children/minors, prisoners, pregnant women, people with cognitive impairments, and others with limited autonomy or who are susceptible to coercion. With minors, you need parental/guardian consent plus the child's assent. The three bedrock principles from the Belmont Report anchor it all: respect for persons (autonomy/consent), beneficence (maximize benefit, minimize harm), and justice (fair distribution of research burdens and benefits).

Clinical Pearl: The IRB's job is prospective — it approves studies before they run. Nail the non-negotiable consent elements (voluntary, informed of risks/benefits, free to withdraw anytime) and remember that deception requires post-study debriefing and that vulnerable populations trigger heightened safeguards.
