Why does talking about ethics matter?
Evidence shows that discussing ethics results in more ethical behavior.
It also:
However, I am
“I would wager that many students do not appreciate the consequences of misconduct when working on a federally funded project. If they fabricate or falsify even a ‘small amount’ of data, they cannot get off with just a slap on the wrist. Suspected misconduct must be reported to the institution’s integrity officer. If found guilty, he or she will likely be debarred from working on federally sponsored research for several years.”
— Marshall Thomsen, APS Newsletter: NSF Ethics Education Requirements
NSF / America COMPETES Act — Federal Register, Vol. 74 No. 160, August 20, 2009
The National Science Foundation requires that each institution applying for financial assistance for science and engineering research describe in its grant proposal a plan to provide appropriate training and oversight in the responsible and ethical conduct of research to undergraduate students, graduate students, and postdoctoral researchers participating in the proposed research project.
💡 Fear of the law is not our primary reason for ethical conduct — but it is real. The deeper reason: our work has far-reaching consequences for human health, global society, and the environment.

It can be obvious or subtle:
Even unintentional plagiarism is a violation.
Tools publishers use:
The numbers (Nature, 466, 2010): In one pilot on three journals, CrossCheck caused the publisher to reject 6%, 10%, and 23% of already-accepted papers.
⚠️ New concern: AI citations
AI tools (ChatGPT, etc.) are notorious for generating false or hallucinated citations — real-sounding papers that do not exist.
If you use an AI-generated citation without verifying it, you may unknowingly submit fabricated references.
Always verify every citation at its source.
Always cite when you:
Citation is not a burden — it gives you advantages:
💡 Self-plagiarism: Reusing substantial portions of your own prior published work without disclosure is also a violation. If in doubt, cite yourself.
Situation A: You are writing your REU final report. Your methods section closely follows the protocol paper your lab published two years ago. You paraphrase most sentences but don’t cite the original paper because “it’s just a methods section.”
Situation B: You ask an AI assistant to help you write your literature review. It generates a citation — author, journal, volume, page numbers — that looks completely real. You include it without checking.
Situation C: You are writing a report and find a paragraph in a Wikipedia article that perfectly summarizes the background. You rewrite each sentence in slightly different words but follow the same structure and don’t cite Wikipedia.
🗳️ Discussion: Which of A, B, or C is plagiarism? Which is the most serious? What should you do in each case?
Fabrication — making up data or results and recording or reporting them
Falsification — manipulating research materials, equipment, or processes, or changing or omitting data so the record is not accurately represented
Both are federal offenses when they occur on federally funded research.
The trend is alarming:

Not every questionable decision is misconduct — but the line matters.
| Acceptable | Misconduct |
|---|---|
| Removing an outlier with documented justification | Removing an outlier because it hurts your p-value |
| Image brightness adjustment applied uniformly | Cropping or masking a gel band |
| Rounding to significant figures | Inventing a measurement |
| Choosing one statistical test over another | Running multiple tests and only reporting the favorable one |
💡 The key question: Would a reasonable scientist, knowing your methods, agree this is a legitimate choice? If you’d be embarrassed to explain it, it’s a red flag.
Situation: You run an experiment five times. Four trials confirm your hypothesis; one is a significant outlier — far outside the range of the others. Your mentor says: “Just drop it — it’s probably instrument error. The trend is clearly there.”
The stakes: This result will appear in a conference paper associated with your NSF REU grant. Fabricating or falsifying data on a federally funded project is reportable to the Office of Research Integrity.

What happened
A scientific image-integrity sleuth flagged the validation western blot for one of ThermoFisher’s antibodies.
Why this matters for you
Record everything
Store securely
Retain your data
NSF requires data retention for at least 3 years after a grant ends. Many journals now require data sharing at publication.
Make it reproducible
A stranger — or your future self — should be able to re-run your entire analysis from your lab notebook and code alone, without asking you a single question.
Modeling & statistical integrity:
Real-world consequence
In 1999, NASA lost the $327 million Mars Climate Orbiter when one engineering team used pound-force-seconds and another used Newton-seconds in their trajectory software. The spacecraft entered the Martian atmosphere at the wrong altitude and was destroyed.
The error wasn’t fraud — but the damage to careers, the mission, and the program’s credibility was enormous.
Good data practice would have caught it.
Situation: A PhD student graduates and leaves for a position across the country. Their personal laptop has all of the raw experimental data from their dissertation — data that was never uploaded to any lab server. Two years later, a journal reviewer challenges a result in the published paper and requests the raw data. The former student no longer responds to emails.
Questions to work through:
APS / ICMJE standard — authorship should be limited to those who have made a significant contribution to the:
Authorship confers both credit and responsibility. An author is accountable for the integrity of the work — not just their slice of it.
What does NOT qualify:
These warrant an acknowledgment, not authorship.
Common friction points: Adding, deleting, or changing the order of authors after a draft is complete is one of the most frequent sources of conflict in academic research.
Situation
Jan and Keith are engineering faculty members seeking tenure. Jan developed a paper during his PhD that he never published. He discusses the idea with Keith, and they agree to revise it together. Jan does most of the revision work; Keith’s contributions are minimal — but Jan agrees to include Keith as co-author to help Keith’s tenure case. The article is accepted and published.
🗳️ Discussion questions:
Situation: Over the summer, you’ve designed and run your experiments, generated the figures, and written most of your final report. Your graduate student mentor helped you set up equipment in the first week and answered questions throughout the summer. They shaped your project, but you did all the hands-on work and most of the analysis. At the end of the summer, your mentor submits an abstract to a conference. The author list reads: [Grad Student], [Your Name], [Another Student], [PI].
🗳️ Discussion:
Your mentor is responsible for:
You are responsible for:
The reality:
Many misconduct cases involve trainees who felt they couldn’t say no to a PI — or were afraid to report a problem.
If you need help:
Situation: You are an REU student in your final two weeks. Your PI wants to include your results in a paper being submitted to a high-impact journal — a paper that could significantly help your graduate school applications. While reviewing your figures, your PI says:
“These fluctuations are just instrument noise — can you smooth the data a little before the figure? The trend is clearly there.”
You’re not sure if this is a standard processing step or something else.
🗳️ Discussion:
A conflict of interest exists when personal interests could — or appear to — compromise professional judgment.
💰 Financial
Stock, consulting fees, or a startup that benefits from your research results
🤝 Personal
Reviewing a close friend’s paper, evaluating a competitor’s grant, or hiring a relative
🧠 Intellectual
Strong prior public commitment to a hypothesis that your experiment might disprove
💡 A conflict of interest is not automatically misconduct. Disclosing it and managing it properly — recusing yourself, seeking oversight — is the correct ethical response. Concealing it is what creates the problem.
Situation: Your PI holds equity in a startup company that is developing a product based on the research direction of your lab. Your summer project is directly testing the core hypothesis behind that product. The PI has not disclosed this to you. When your results come in — mixed, not as strong as hoped — the PI suggests you frame the conclusions more positively in your final report.
The broader picture: Your REU stipend comes from an NSF grant. The PI’s company could benefit financially from the published version of your work.
🗳️ Discussion:
IRB — Institutional Review Board Protects human research participants
IACUC — Institutional Animal Care and Use Committee Protects animal subjects
⚠️ Bottom line: Never collect data from humans or animals without prior written IRB or IACUC approval. No exceptions — even for a “quick pilot.”
Situation: Your REU project involves understanding how engineers in your department make design decisions under uncertainty. You design a short 10-question survey and send it to 30 graduate students via email. You plan to include the results in your final report and, potentially, a conference paper.
A labmate mentions you should have gotten IRB approval first. You didn’t know surveys required it. You’ve already received 20 responses.
Note: Even anonymous surveys of human subjects may require IRB review, depending on the questions and how results will be used.
