Unit 8: Ethics in Research

Research ethics is the framework of moral principles that governs how knowledge is generated, reported, and applied, ensuring that the pursuit of truth does not harm participants, colleagues, or society. It emerged as a formal discipline after abuses documented at the Nuremberg trials (1947) and codified through instruments such as the Declaration of Helsinki (1964) and the Belmont Report (1979), which named respect for persons, beneficence, and justice as its pillars.

Defining features that later sections rely on:

• Normative, not optional: Ethics prescribes what a researcher ought to do, distinct from legality (what one is required to do) and methodology (what works).
• Applies across the whole cycle: Design, data collection, analysis, publication, and reuse all carry ethical duties.
• Balances competing interests: Truth-seeking, participant welfare, and public benefit must be weighed against one another.
• Governed institutionally: Enforced through Institutional Review Boards (IRBs), ethics committees, and codes such as those of the Singapore Statement (2010).

II. Objectivity and Subjectivity in Research

The tension between reporting the world as it is and the researcher's unavoidable perspective.

A. Objectivity

Objectivity is the commitment to let evidence, not preference, decide conclusions.

• Bias avoidance: Guard against selection, confirmation, and funding bias, e.g. registering hypotheses before data collection so results cannot be retrofitted.
• Reproducibility: Report methods precisely enough that another team obtains the same result from the same data.
• Transparent statistics: Disclose all measured variables, not only the "significant" ones, to prevent p-hacking.

B. Subjectivity

Subjectivity is the influence of the researcher's values, context, and interpretation on the inquiry.

• Legitimate role: In qualitative and ethnographic work, the researcher is the instrument, so interpretation is expected.
• Reflexivity as the control: State one's standpoint and potential influence explicitly rather than pretending neutrality.
• The paired contrast:
  1. Objectivist stance: Facts exist independently; the goal is to minimise the observer's footprint.
  2. Interpretivist stance: Meaning is co-constructed; the goal is to make the observer's footprint visible and accountable.

III. Principles of Personal Conduct

The duties a researcher owes to the reliability of the work itself: integrity, carefulness, and competence.

A. Integrity

Integrity is honesty and consistency in every representation of the research.

• No fabrication: Never invent data points or results that were not observed.
• No falsification: Never manipulate images, delete inconvenient outliers, or alter equipment readings.
• Kept promises: Honour agreements with participants, funders, and collaborators; do not overstate findings to secure grants.

B. Carefulness

Carefulness is diligence in avoiding careless error and self-deception.

• Record-keeping: Maintain dated lab notebooks or version-controlled data files so any figure can be traced to its raw source.
• Error checking: Recompute key calculations and audit code, since an undetected unit-conversion slip can invalidate a whole study.
• Peer scrutiny: Invite colleagues to review protocols before, not after, data collection.

C. Competence

Competence is maintaining and honestly representing the skills the work requires.

• Qualification match: Undertake only analyses one is trained for, e.g. not running a mixed-effects model without understanding its assumptions.
• Continuing education: Keep current with methods and instruments in one's field.
• Recognising limits: Bring in a statistician or domain expert rather than guessing, and disclose the boundaries of one's expertise.

IV. Sharing and Ownership of Knowledge

The duties governing how results and ideas are disclosed and attributed: openness and respect for intellectual property.

A. Openness

Openness is the willingness to share data, results, methods, and criticism.

• Data sharing: Deposit datasets in public repositories where consent and confidentiality allow, enabling verification.
• Methodological transparency: Publish protocols, code, and negative results, since suppressed null findings distort the literature.
• Receptiveness to critique: Treat peer review and replication attempts as strengthening, not attacking, the work.

B. Respect for Intellectual Property

Respect for intellectual property is honouring the ownership and credit due to ideas and creative works.

• Attribution: Cite every source of ideas, data, and wording; give authorship only to genuine contributors.
• Avoiding plagiarism: Do not present another's words or ideas as one's own; quote and reference verbatim borrowings.
  • Self-plagiarism: Reusing one's own prior text without citation is also a breach.
• Patents and copyright: Respect licences, obtain permissions for reproduced figures, and honour confidentiality of unpublished manuscripts seen while reviewing.

V. Duties to Research Participants

The protections owed to the people studied: confidentiality and informed consent.

A. Confidentiality

Confidentiality is safeguarding information participants share in trust.

• Anonymisation: Strip or code identifiers so individuals cannot be traced from published data.
• Secure storage: Keep records encrypted and access-restricted; separate identifying keys from response data.
• Limited disclosure: Share only with those authorised, and state limits in advance (e.g. mandatory reporting of certain harms).

B. Informed Consent

Informed consent is voluntary agreement to participate given with full understanding.

• Disclosure: Explain purpose, procedures, risks, benefits, and duration in plain language.
• Comprehension: Confirm the participant genuinely understands, adapting for children or vulnerable groups who may need a guardian's consent.
• Voluntariness: Ensure no coercion or undue inducement, and affirm the right to withdraw at any time without penalty.
• Documentation: Record consent, typically by signed form, before any data collection begins.

Worked illustration: A psychologist recruiting students must not offer grade credit that effectively forces participation (voluntariness), must describe any deception debriefing plan (disclosure), and must code responses by ID number stored separately from names (confidentiality) — three principles operating on one study.

VI. Duties to Society and the Law

The wider obligations that extend beyond the study: social responsibility and legality.

A. Social Responsibility

Social responsibility is the duty to promote public good and prevent harm through research.

• Beneficence: Aim research at reducing harm and advancing welfare; weigh whether foreseeable benefits justify risks.
• Dual-use awareness: Consider how findings could be misused, e.g. pathogen research that could aid bioweapon design, and mitigate accordingly.
• Public communication: Report to media and policymakers accurately, without hype that could mislead health or policy decisions.

B. Legality

Legality is compliance with the laws and regulations governing research.

• Regulatory approval: Secure IRB or ethics-committee clearance before starting human or animal studies.
• Statutory duties: Follow data-protection law (such as GDPR), animal-welfare statutes, and health-and-safety regulations.
• The paired contrast:
  1. Legal but unethical: An action may satisfy the letter of the law yet breach moral duty, e.g. exploiting a consent loophole.
  2. Ethical but restricted: A morally sound aim may still be legally constrained, requiring the researcher to seek proper authorisation rather than proceed unilaterally.

VII. Integrating the Principles in Practice

How the individual duties combine into responsible conduct of research.

A. Interaction and Trade-offs

The principles reinforce one another but occasionally conflict.

• Reinforcement: Openness supports objectivity because shared data invites verification; integrity underpins competence because honest self-assessment sets realistic limits.
• Tension: Openness can clash with confidentiality when data sharing risks re-identifying participants; the resolution is anonymisation or controlled-access sharing.
• Priority rule: Participant welfare and confidentiality generally outrank the researcher's interest in publishing complete raw data.

B. Governance and Enforcement

Ethics is sustained by structures, not goodwill alone.

• Institutional Review Boards: Independent committees that approve, monitor, and can halt studies involving human subjects.
• Codes and statements: Professional bodies publish binding codes; the Singapore Statement (2010) lists honesty, accountability, professional courtesy, and good stewardship as global responsibilities.
• Sanctions: Misconduct — chiefly fabrication, falsification, and plagiarism — can bring retraction, funding loss, and dismissal, signalling that ethics carries real consequences.

C. Significance

Ethical practice is the foundation of research credibility.

• Trust: Public willingness to fund research and enrol as participants depends on a track record of ethical conduct.
• Cumulative knowledge: Since science builds on prior work, a single fabricated result can corrupt whole lines of inquiry, wasting years of downstream effort.
• Justice in benefit and burden: Fair selection of participants ensures neither risks nor rewards fall unfairly on any group, tying individual studies to broader social equity.
