The phrase "conflict of interest" sounds accusatory, but it describes something ordinary: a secondary interest — money, relationships, rivalry — that could, even unintentionally, bias judgement. Almost everyone has them at some point. The integrity question is never "do you have one?" but "did you disclose it?"
What counts
- Financial interests — funding, employment, consulting, stock, patents, honoraria, paid expert testimony, or travel.
- Non-financial interests — personal relationships, academic rivalries, strongly held positions, or institutional loyalties that could shape how work is done or judged.
A conflict can be real or merely perceived; both matter, because trust depends on how things look as well as how they are.
Who needs to disclose
Everyone in the process. Authors declare interests relevant to the work (many journals use the ICMJE disclosure form). Reviewers decline or flag papers where they have a stake. Editors step back from decisions where they are conflicted. Disclosure lets readers weigh the work with full information, rather than discovering a hidden interest later.
How to do it well
Disclose early — at submission, not after questions are asked — and disclose fully, erring toward including something borderline rather than omitting it. Be specific about what the interest is and how it relates to the work. If in doubt, ask the editor.
Transparency here is not a confession; it is a courtesy and a safeguard. It protects you, and it lets the scholarly record be read honestly. Trust, again, comes from openness about how the work was done.
