Introduction

One supervisor suggests expanding your literature review. Another recommends shortening it. One advises using qualitative research, while another encourages a quantitative approach. After listening to both, you're left wondering:

"Whose advice should I follow?"

Receiving conflicting advice during your dissertation can be confusing and frustrating. Whether you have a primary supervisor, a second supervisor, or feedback from module leaders and dissertation reviewers, differing opinions are common in academic research.

The good news is that conflicting feedback doesn't necessarily mean someone is wrong. Academic research often involves multiple valid perspectives. Your task as a student is to evaluate those perspectives critically and make informed decisions based on your research objectives and your university's assessment criteria.

This guide explains how to manage conflicting dissertation advice professionally while maintaining confidence in your research.

Why Supervisors Sometimes Disagree

Academic research is rarely black and white.

Supervisors may disagree because they have different:

• Research backgrounds.

• Academic disciplines.

• Methodological preferences.

• Teaching experiences.

• Publishing expertise.

• Personal supervision styles.

For example, one supervisor may prioritise theoretical depth, while another focuses on practical application. Both viewpoints can be academically valid.

Don't Assume One Person Is Right

When advice conflicts, avoid immediately choosing the opinion you prefer.

Instead, ask:

• Which advice aligns with my research question?

• Which recommendation supports my methodology?

• Which option meets the dissertation marking criteria?

• Which approach is supported by academic literature?

The strongest decision is one based on evidence rather than personal preference.

Review Your Dissertation Objectives

Return to the core purpose of your dissertation.

Consider:

• Your research question.

• Your aims and objectives.

• Your methodology.

• Your target audience.

• Your assessment rubric.

Any changes you make should strengthen these elements rather than distract from them.

Compare the Advice Side by Side

Creating a comparison table can help clarify your options.

Seeing the options visually often makes the decision easier.

Ask for Clarification Professionally

If two supervisors provide conflicting recommendations, request clarification respectfully.

Instead of saying:

"You disagree with each other."

Try:

"I've received two different suggestions regarding my methodology. Could you help me understand which approach would better align with my research objectives?"

This encourages constructive discussion rather than confrontation.

Use Academic Evidence to Support Your Decision

Your dissertation should be guided by credible evidence, not opinions alone.

Review:

• Peer-reviewed journal articles.

• Methodology textbooks.

• Systematic reviews.

• University research guidance.

• Discipline-specific standards.

If academic literature strongly supports one approach, that evidence can help justify your decision.

Keep Records of Feedback

Maintain a revision log that records:

• Date of feedback.

• Supervisor comments.

• Your response.

• Changes made.

• Academic justification.

This creates a clear record of your decision-making process and helps you explain your reasoning if needed.

Focus on the Assessment Criteria

Your dissertation will ultimately be assessed against your university's marking rubric.

Typical criteria include:

• Research quality.

• Critical analysis.

• Methodological justification.

• Originality.

• Academic writing.

• Referencing.

If conflicting advice arises, prioritise the approach that best satisfies these assessment criteria.

Know When to Make an Independent Decision

At postgraduate level, students are expected to demonstrate independent academic judgement.

Sometimes there is no single "correct" answer.

If you have:

• Considered both viewpoints,

• Reviewed relevant literature,

• Evaluated the assessment criteria,

• Justified your reasoning,

then making an informed independent decision is entirely appropriate.

Avoid Common Mistakes

Students often make the situation worse by:

• Trying to satisfy every suggestion simultaneously.

• Changing direction repeatedly.

• Ignoring their research question.

• Following advice without understanding it.

• Becoming overwhelmed and delaying progress.

A clear, evidence-based approach is usually more effective than attempting to accommodate every opinion.

Academic Integrity Matters

Even when supervisors disagree, maintain high academic standards.

Always:

• Cite sources accurately.

• Justify methodological decisions with evidence.

• Follow your university's referencing style.

• Ensure your analysis and conclusions remain your own original work.

Independent thinking is an important part of academic integrity.

Conflicting Advice vs Best Response

Final Thoughts

Conflicting advice from dissertation supervisors can feel overwhelming, but it is often a reflection of the diverse perspectives that exist in academic research. Instead of viewing disagreement as a problem, treat it as an opportunity to evaluate evidence, strengthen your critical thinking, and make informed decisions that support your research objectives.

By comparing different recommendations, consulting credible academic sources, referring to your university's assessment criteria, and communicating professionally with your supervisors, you can confidently navigate conflicting feedback. Developing the ability to justify your academic choices is a valuable research skill that will benefit you throughout your academic and professional career.
