Core Ethical Protections
Modern research ethics protect participants through strict standards born from historical failures. Informed consent requires that participants understand a study's purpose, risks, and benefits before agreeing.
Participants always retain the right to withdraw at any point without penalty. Confidentiality protects data from outside linkage to identities, while anonymity means even researchers cannot link data to a person.
| Protection | Definition |
|---|---|
| Informed Consent | Prior agreement based on full understanding |
| Right to Withdraw | Freedom to exit at any time without penalty |
| Confidentiality | Data kept safe from outside identification |
| Anonymity | Complete separation of data from identity |
Deception, IRB, and Belmont
Deception is only permitted when scientifically justified, lacking a non-deceptive alternative, and involving minimal risk. It demands debriefing—fully explaining the true purpose afterward.
Every study needs approval from an Institutional Review Board (IRB) before data collection begins.
| Belmont Principle | Requirement |
|---|---|
| Respect for Persons | Autonomous treatment, consent |
| Beneficence | Maximize benefits, minimize harm |
| Justice | Fair distribution of risks/benefits |
Common pitfall: Assuming debriefing alone justifies deception. It must also meet strict necessity and minimal-risk criteria beforehand.
