Can Professional Rivalries or Relationships Create Conflicts of Interest?

When does knowing another researcher become a conflict of interest?

Academic research is built on relationships. Researchers collaborate, supervise students, train under mentors, work with colleagues, compete for funding, disagree publicly, and encounter the same people repeatedly at conferences, journals, and professional societies.

Then one day you are asked to review a former student's manuscript, evaluate a collaborator's grant, assess a close friend's promotion case, or review research produced by a direct professional rival.

Knowing someone is not automatically a conflict. The important question is whether the relationship creates a competing interest that could compromise, or reasonably call into question, your impartial performance of the specific role.

Relationships become conflicts when they meaningfully compete with impartial judgment

Research relationships can create interests even when no money changes hands

A relationship can give you a stake in someone else's outcome

Imagine reviewing a grant application from your doctoral student. You may sincerely intend to be rigorous, but you also have an understandable interest in seeing your student's career succeed. Now imagine reviewing the application of a researcher with whom you are engaged in a bitter competition for priority over a discovery. The direction of the interest changes, but the underlying concern is similar.

Your responsibility as a reviewer is to evaluate the work on its merits. Your relationship with the applicant may create another interest that competes with that responsibility.

The U.S. Office of Research Integrity uses close colleagues and students as straightforward examples of personal conflicts in review because a researcher's interest in their success can compete with evidence-based judgment.

Relationships can create positive or negative conflicts

Conflict-of-interest discussions sometimes focus on favoritism. A close friend, collaborator, mentor, student, or colleague may indeed create an incentive toward favorable treatment.

But negative relationships matter too. A professional rival may benefit from another researcher's proposal being rejected, publication being delayed, or scientific reputation being weakened. ICMJE explicitly identifies personal relationships or rivalries and academic competition among interests that may represent or be perceived as conflicts.

Neither situation proves that the person will act unfairly. The concern is that the relationship gives them a stake in an outcome they are supposed to judge impartially.

Peer review is where relationship conflicts become especially visible

Peer reviewers influence publication and funding decisions while gaining temporary access to other researchers' unpublished work. For that reason, journals and funding agencies commonly require reviewers to disclose relevant conflicts before participating.

ICMJE states that reviewers should disclose relationships or activities that could bias their opinions and should recuse themselves from particular manuscripts when the potential for bias exists.

NIH peer-review rules provide a more formal example. NIH identifies professional associations with people holding major roles in a proposed project among circumstances that can create conflicts in initial peer review. Specific NIH regulations and policies then determine whether a particular relationship disqualifies a reviewer.

Collaboration does not create a permanent conflict

Researchers collaborate extensively, particularly in small or specialized fields. Treating anyone who has ever coauthored a paper as permanently conflicted would make some expert-review panels rather lonely.

The relevance of a collaboration often depends on recency, closeness, frequency, financial or professional interdependence, and the rules of the review system. Some policies specify look-back periods or particular professional relationships. Others use broader standards.

This is why researchers should not invent a universal rule such as “any coauthor within five years is automatically conflicted.” A particular organization may indeed impose a defined period, but that period belongs to that policy rather than to research ethics universally.

Mentor and trainee relationships deserve particular attention

Mentorship can create long-lasting professional loyalties. A supervisor may have invested substantial effort in a student's development, coauthored work with them, supported their employment, and become personally committed to their success.

Conversely, a former trainee may feel strong loyalty toward a mentor whose work they are asked to evaluate. The passage of time may reduce the relevance of some relationships, but policies differ in how they treat former mentors and trainees.

ORI specifically advises that researchers generally should not serve as reviewers for grants and publications submitted by close colleagues and students. Earlier National Academies guidance similarly identifies direct competitors and mentors among situations that can compromise impartial review.

Working at the same institution may matter, but not identically everywhere

Institutional colleagues may share resources, leadership, funding, departmental goals, reputational interests, or reporting relationships. These connections can create interests that extend beyond simple acquaintance.

Some review policies therefore treat certain institutional affiliations as conflicts. Others distinguish between large organizations, departments, direct supervisory relationships, or other forms of institutional proximity.

Do not assume that sharing a university name always creates a conflict or that it never does. Apply the rule governing the particular review or decision.

Competition is normal until it intersects with evaluative power

Researchers routinely compete for grants, positions, prestige, journal space, priority, students, and recognition. Competition alone does not necessarily disqualify people from commenting on each other's published ideas.

The ethical stakes change when a competitor receives confidential material or formal authority over another researcher's opportunity. A reviewer deciding whether a direct competitor receives funding occupies a different position from two scholars publicly debating the interpretation of already published evidence.

This is where career-related competing interests and relationship conflicts often intersect.

A scientific disagreement is not automatically a professional rivalry

Researchers can criticize one another's theories, methods, or conclusions without having a personal conflict. Vigorous disagreement is part of scholarship.

A rivalry becomes more relevant when there is a significant competitive or personal stake beyond ordinary intellectual disagreement. Examples might include direct competition for the same opportunity, a serious ongoing dispute, a relationship involving litigation, or another circumstance in which one person's success or failure materially affects the other.

Equally, strong intellectual beliefs should not be automatically recast as personal animosity simply because two researchers disagree.

The correct response may be disclosure or recusal

Researchers should not always decide for themselves that a relationship is harmless. Review systems typically place responsibility on reviewers to disclose relevant circumstances so an editor, scientific review officer, committee, or other responsible authority can apply the governing rules.

ICMJE recommends recusal when the potential for bias exists in manuscript review. NIH uses defined conflict rules for its review processes. The precise threshold therefore depends on context.

In less severe circumstances, disclosure may allow the responsible body to determine that participation remains appropriate. In more direct conflicts, replacing the reviewer or decision-maker is often simpler and more credible than trying to manage an avoidable conflict during the decision itself.

Four relationships do not necessarily produce the same decision

The lesson is not that every relationship can be assigned a universal ethical score. It is that “I know this author” contains too little information. The nature and relevance of the relationship determine what needs to happen next.

Common mistakes when assessing relationship conflicts

Evaluate the relationship before you evaluate the work

When you receive a manuscript, grant, promotion case, research protocol, or other material for evaluation, check your relationship to the people involved before beginning substantive review.

Early disclosure is particularly useful in peer review. It is much easier for an editor to replace a reviewer before confidential material has been examined than to repair a compromised review process afterward.
