The Role of Insights in Medical Affairs: What Aspiring MSLs Must Know
Mar 08, 2026
One of the most misunderstood responsibilities of an MSL is insight generation. Many aspiring MSLs hear the word “insights” during interviews but struggle to explain what it actually means.
Insights are not summaries. They are not opinions. And they are not sales feedback.
In this post, we explain what insights mean in medical affairs, why they matter, and how aspiring MSLs can demonstrate insight before ever stepping into the role.
What Are Insights in Medical Affairs
Insights are meaningful observations gathered from scientific exchange that help inform medical strategy.
They often relate to:
- Gaps in clinical understanding
- Emerging practice patterns
- Unmet patient needs
- Questions raised by KOLs
- Real-world challenges with existing therapies
An insight connects field conversations to broader strategic implications.
Why Insights Matter So Much
Medical affairs teams rely on insights to:
- Shape evidence generation plans
- Inform medical education strategies
- Identify areas for future research
- Support lifecycle management decisions
MSLs act as the bridge between the field and internal teams. Without high-quality insights, that bridge loses value.
What Insights Are Not
Aspiring MSLs often confuse insights with basic feedback.
Not insights:
- “Doctors like Drug A”
- “Clinicians want more data”
- “Physicians asked about dosing.”
Better insight framing:
“Multiple clinicians expressed uncertainty around long-term safety data in elderly patients, suggesting a need for targeted education or additional evidence generation.”
How Aspiring MSLs Can Practice Insight Thinking
You do not need industry experience to develop this skill.
You can practice by:
- Reflecting on patterns from clinical rotations or practice
- Noting recurring questions during journal clubs
- Thinking about why clinicians ask certain questions
- Connecting observations to broader system challenges
Insight thinking starts with curiosity and reflection.
How Insights Show Up in Interviews
Hiring managers often assess insight capability through questions like:
- What trends are you seeing in your therapeutic area?
- Tell me about a recurring question you encounter and why it matters
- How would you share field observations with internal teams?
Strong answers show interpretation, not reporting.
Final Thoughts
Insights are the currency of medical affairs. They transform conversations into strategy and data into direction. Aspiring MSLs who understand and practice insight thinking early stand out as more prepared, strategic, and aligned with the role.
