Introduction: Life Science Begins with Honesty
Biology is the science of life — and integrity is the life of science. From cell structure to ecosystems, IB Biology asks students to observe, question, and analyze truthfully. Integrity ensures that every experiment, every graph, and every conclusion reflects reality, not convenience.
The IB Biology Guide (IBO, 2023) reminds students that “academic honesty and ethical awareness underpin all biological investigation.” That includes respecting living organisms, collecting data accurately, and acknowledging every source of information or inspiration.
This guide explores how IB Biology students can uphold integrity throughout their coursework and Internal Assessments (IAs), combining ethical research with scientific precision.
Quick Start Checklist: Ethical Biology Practices
- Respect all living organisms and environments.
- Collect and report data truthfully — no fabrication.
- Acknowledge all sources and prior research.
- Use technology and AI responsibly.
- Reflect honestly on experimental limitations.
- Follow IB and school safety and ethics guidelines.
Integrity in biology means treating both data and life with equal respect.
Understanding Integrity in Biological Research
Integrity in biology merges three dimensions:
- Scientific honesty — Reporting observations and data exactly as collected.
- Ethical responsibility — Protecting organisms and the environment during research.
- Academic credit — Citing all references and acknowledging collaboration appropriately.
As biologist Rachel Carson wrote in Silent Spring, “The obligation to endure gives us the right to know.” Ethical biology begins with this balance of curiosity and conscience.
Ethical Experimentation in IB Biology
Many IB Biology investigations involve living organisms. Ethical responsibility is essential.
- Use non-invasive and humane methods for all biological testing.
- Avoid causing stress or harm to animals or plants.
- Obtain consent when working with humans (e.g., surveys or fitness studies).
- Follow your school’s safety and disposal procedures.
- Seek teacher approval for experiments involving living specimens.
The IB explicitly prohibits experiments that could harm living systems — ethical approval is part of scientific credibility.
Accurate Data Collection and Analysis
Data integrity determines the quality of your findings.
To maintain accuracy:
- Record raw data immediately and in original form.
- Use correct SI units and uncertainty notation.
- Include all results, even unexpected or “incorrect” ones.
- Avoid rounding until the final stage of analysis.
- Keep digital and handwritten copies of all data.
Even a single fabricated value can undermine an entire investigation — but honest data, even flawed, strengthens your credibility.
Avoiding Fabrication and Selective Reporting
One of the most serious integrity breaches in biology is manipulating data to fit expectations. Avoid this by:
- Presenting all data points, including anomalies.
- Explaining irregular results rather than excluding them.
- Using graphs and error bars transparently.
- Reflecting on how errors or biological variation influenced outcomes.
Science depends on transparency — integrity means accepting complexity rather than concealing it.
Citing Sources and Acknowledging Influence
Biology builds on centuries of shared knowledge — acknowledging your sources honors that tradition.
You must cite:
- Textbooks, journals, and online research.
- Images, diagrams, or graphs you did not create.
- Data sets from secondary sources (e.g., WHO, FAO, UN).
- Methods or ideas adapted from published experiments.
Example:
Population data adapted from the World Health Organization Global Health Observatory (2024).
Always include a full reference list. Proper citation prevents plagiarism and demonstrates academic maturity.
Using Technology and AI Ethically
Digital tools and AI can support biological analysis — but they must not replace scientific reasoning.
- Use tools like Excel or LoggerPro to process and graph data, not generate conclusions.
- Do not use AI to write your IA or explain results.
- Disclose software and data processing tools in your report.
- Verify AI-generated calculations manually before inclusion.
Technology helps organize evidence; integrity ensures you understand it.
Honest Reflection in Evaluation
Integrity extends to how you interpret your findings.
Reflect honestly on:
- The reliability and validity of your experiment.
- Uncertainties and limitations in data collection.
- Sources of human error or environmental interference.
- How future investigations could improve upon your design.
IB examiners value critical self-awareness — not perfection. Honest reflection shows you understand biology as a living, evolving process.
Collaboration and Individual Work
Biology labs often involve teamwork, but independence remains essential.
- You may share equipment and discuss procedures.
- Each student must collect and analyze data independently.
- Avoid sharing digital data files or written work.
- Credit peers for assistance or collaboration.
Integrity in collaboration means cooperation without duplication.
Environmental and Cultural Responsibility
Ethical research extends beyond the lab.
- Avoid wasteful or environmentally harmful experiments.
- Dispose of biological material safely and responsibly.
- Be culturally sensitive when studying ecological or human systems.
- Reflect on how your investigation impacts both science and society.
Environmental awareness and integrity go hand in hand — responsible science respects the world it studies.

Conclusion: Integrity Is the DNA of Science
Every living system depends on integrity — so does every scientific one.
Integrity in IB Biology means more than avoiding misconduct; it means honoring truth, respecting life, and learning through honest inquiry.
When you conduct research ethically and analyze with transparency, you contribute to both the IB community and the global pursuit of scientific understanding.
Integrity ensures that your discoveries grow from roots of honesty.

Frequently Asked Questions
1. What counts as misconduct in IB Biology?
Fabricating or manipulating data, harming organisms, or copying another student’s IA are serious violations of IB integrity rules.
2. Can I use human participants in my investigation?
Yes, with informed consent and ethical approval from your teacher. Avoid sensitive personal data.
3. What if my results contradict my hypothesis?
Report them honestly and explain possible biological causes — science values truth, not confirmation.
4. Can I use AI or statistical software?
Yes, for data visualization and calculations, but you must understand and verify every step. Always disclose tool use.
