Scientific Writing (9 of 11): Writing a Compelling Discussion (#175)

Updated: Jan 4



Ever wonder what separates a good scientific manuscript from a truly impactful one? It’s often the Discussion section - the part where your research transforms from a collection of data points into a compelling narrative that shapes understanding and sparks innovation.

 

The Discussion isn’t just an afterthought - it’s your platform to connect the dots,

share insights and inspire the next breakthrough.

 

Mastering the Discussion Section of a Veterinary Scientific Manuscript

 

The Discussion section is arguably the most creative and analytical part of a scientific manuscript. It’s where you step beyond raw data to interpret, connect, and speculate, transforming results into meaningful insights. This is your opportunity to tell the story behind your research, highlight its significance, and point to the next steps for your field.

 

The Importance of Keeping Results and Discussion Separate

 

While it may be tempting to merge your Results and Discussion sections, keeping them separate is usually the better choice. Why? Because clarity and focus are key.

 

  • Objectivity in Results: The Results section is for presenting your findings without interpretation. This clear presentation allows readers to form an initial impression of your data.

 

  • Analysis in Discussion: The Discussion is where you unpack the meaning of those results, frame them in the context of existing research, and speculate on their implications.

 

Separating these sections also gives you an additional forum to reiterate your main points, ensuring your message is conveyed effectively.

 

The Pyramid Structure: Specific to Broad

 

Think of the Discussion section as a pyramid. Start at the apex with your most specific findings, then broaden the scope as you go.

 

  • Key Findings

o   Open with a concise summary of your key results. This should answer the primary research question your study sought to address. For example:

o   The phylogenetic data presented here indicate that Chimps and Humans are in the same taxonomic family.

o   This immediate clarity helps anchor your readers in the take-home message of your work.

 

  • Contextual Integration

o   After stating your findings, place them within the larger framework of the field. Discuss how they align with or differ from previous studies. Highlight any surprising or novel elements, using references to support your arguments:

o   Our findings align with Jones et al. (2020), who demonstrated similar phylogenetic relationships. However, our study extends this work by…

 

  • Implications and Applications

o   Once you’ve contextualized your results, discuss their broader significance. How might these findings influence veterinary practices, policy, or future research? For instance:

o   These results suggest a potential new diagnostic marker for identifying early stages of feline leukemia, which could improve clinical outcomes.

 

  • Limitations

o   Acknowledging the limitations of your study adds credibility and shows thoughtful consideration of your research. Discuss methodological constraints, sample size, or external factors that may have influenced your results. This transparency is essential for a balanced Discussion.

o   One limitation of this study was the small sample size, which may affect the generalizability of our findings.

 

  • Speculation and Future Directions

o   The final paragraphs should explore broader implications and suggest areas for future research. Speculation here is encouraged but should be clearly marked as such:

o   We speculate that the similarities in this phylogenetic family could have implications for zoonotic disease transmission. Further studies are needed to explore this possibility.

 

Keep It Concise and Engaging

 

While the Discussion provides room for interpretation and speculation, brevity is essential. A tightly written, five-to-six-paragraph Discussion is more likely to retain the reader’s interest and leave a strong impression.

 

  • Avoid Repetition: Don’t reiterate the Results section in detail. Instead, focus on interpretation and significance.

  • Engage Your Audience: Use clear and accessible language. Even complex ideas can be communicated effectively without unnecessary jargon.

  • Be Strategic: Every sentence should serve a purpose, whether it’s reinforcing your key message, providing context, or speculating on future implications.

 

The Role of Speculation

 

Speculation is where the Discussion often comes alive. This is your chance to step beyond your data and explore “what if” scenarios. Done well, it can inspire new avenues of research and demonstrate the broader impact of your work.

 

  • Mark Speculation Clearly: Use explicit phrases like we speculate, this suggests, or it is possible that. This ensures readers can differentiate between established findings and your educated hypotheses.

  • Stay Grounded: While speculation can be bold, it should remain plausible and grounded in your findings. Overly wild claims can detract from your credibility.

  • Tie Back to the Bigger Picture: Speculative statements should connect to the broader implications of your work. For instance:

  • The discovery that Chimps and Humans reside in the same family suggests the potential for comparative veterinary models to bridge gaps in human and animal health research.

 

Common Pitfalls to Avoid

 

  • Overloading with References: While contextualizing your findings is important, excessive citations can clutter your narrative. Be selective and strategic in your references.

  • Overgeneralizing: Be cautious not to overstate the implications of your work. Acknowledge the scope and limitations of your study.

  • Avoiding Limitations: Failing to address limitations can make your Discussion appear one-sided. Acknowledging them demonstrates intellectual honesty and rigor.

 

Rick’s Commentary

 

The Discussion section is your opportunity to leave readers

with a lasting impression of your study’s value.

 

A strong Discussion doesn’t just summarize your work - it inspires readers to think about its broader implications and the possibilities it opens for the field.

 

By crafting a Discussion that is clear, concise, and insightful, you can ensure your veterinary scientific manuscript makes a meaningful impact.
