Research Ethics
Why Research Ethics Matters
"Ethics is not a constraint on research; it is the condition of its legitimacy." โ Paul Ricลur
Research involving human participants, data, or publication carries moral and legal obligations. Ethical failures invalidate results, harm participants, and undermine public trust in science.
Core Ethical Principles (Belmont Report)
| Principle |
Meaning |
Application |
| Respect for Persons |
Autonomy, informed consent, protection of vulnerable |
Voluntary participation, right to withdraw |
| Beneficence |
Maximize benefits, minimize harms |
Risk-benefit analysis, safety monitoring |
| Justice |
Fair distribution of burdens/benefits |
Equitable selection, access to benefits |
1. Institutional Review Boards (IRB) / Research Ethics Committees (REC)
When Is Review Required?
| Category |
Review Level |
Examples |
| Exempt |
Minimal risk, specific categories |
Anonymous surveys, educational tests |
| Expedited |
Minimal risk, no vulnerable groups |
Blood draws, voice recordings, minor changes |
| Full Board |
>Minimal risk, vulnerable populations |
Clinical trials, deception, children/prisoners |

Common IRB Pitfalls
| Issue |
Consequence |
Prevention |
| Incomplete application |
Delays/rejection |
Use IRB checklist, consult early |
| Inadequate consent form |
Non-compliance |
Template + plain language review |
| Missing risk mitigation |
Rejection |
Pre-identify all risks |
| No data management plan |
Conditional approval |
Plan storage, sharing, destruction |
Required Elements (8 Basic + 6 Additional per Common Rule)
Basic Elements:
1. Purpose โ Research aims, duration, procedures
2. Risks โ Foreseeable physical, psychological, social, legal, economic
3. Benefits โ Direct (to participant) and indirect (to society)
4. Alternatives โ Other options (e.g., standard treatment)
5. Confidentiality โ Data protection, who sees data
6. Compensation โ Payment, injury coverage
6. Contacts โ Researcher + IRB for questions/complaints
8. Voluntary โ Right to refuse/withdraw without penalty
Additional Elements (when applicable):
- Unforeseeable risks (e.g., genetic findings)
- Circumstances for termination
- Additional costs
- Consequences of withdrawal
- Significant new findings
- Commercial use / profit sharing
| Principle |
Implementation |

Data Sharing & Reproducibility
| Approach |
When |
Pros |
Cons |
| Controlled access |
Sensitive data |
Protects privacy |
Limits reuse |
| Synthetic data |
High risk |
Zero re-identification |
May lose utility |
| Differential privacy |
Aggregate release |
Mathematical guarantees |
Noise reduces accuracy |
| Data enclaves |
Very sensitive |
Full analysis possible |
Expensive, limited access |
FAIR Principles
| Principle |
Action |
| Findable |
Persistent ID (DOI), rich metadata |
| Accessible |
Standard protocol, auth if needed |
| Interoperable |
Standard vocabularies, formats |
| Reusable |
Clear license, provenance, domain standards |
4. Publication Ethics
Authorship Criteria (ICMJE)
All four required for authorship:
1. Substantial contributions to conception/design OR acquisition/analysis/interpretation
2. Drafting or critical revision for intellectual content
3. Final approval of version to be published
4. Agreement to be accountable for all aspects
Contributors who don't meet all four โ Acknowledge in "Contributions" section
