Can You Trust That Study? 7 Essential Questions to Ask

We live in an era of constant headlines, where tweets, posts, and breaking news clamor for our attention day and night. While instant access to information can be useful, it also creates a lot of noise. Learning to separate sensationalism from solid evidence is essential to making informed choices about our health.

For example, a recent statement from the American Heart Association warned against using coconut oil because of potential increased heart disease risk. That kind of headline is alarming, and it’s reasonable to take the AHA seriously. At the same time, it’s important to look more closely before drawing firm conclusions.

Medical research is complex, and many factors influence study outcomes. To evaluate claims properly, consider these seven key points when reading medical studies:

Here are 7 things to keep in mind when looking at medical studies:

1. Where was the study published?

Check whether the study appears in a reputable, peer-reviewed journal. The quality of a journal and its review process matters. If you’re unsure about a publication’s credibility, ask a healthcare professional, a librarian, or an expert in the field for guidance.

2. Remember that even search engines can be flawed.

Search results are influenced by algorithms that can introduce bias. The first result isn’t always the most reliable. Use multiple sources—academic databases, Google Scholar, and other research tools—to gather a fuller picture rather than relying on a single search.

3. One study is not enough.

A single study—especially a small or poorly designed one—doesn’t overturn decades of consistent research. Look for meta-analyses, systematic reviews, or multiple independent studies that replicate findings. Evaluate study design and sample size to judge whether the conclusions are robust.

4. Find out who is funding the research.

Funding sources can introduce conflicts of interest. While financial support doesn’t automatically invalidate results, it’s important to be aware of who funded the study and whether they had a vested interest in particular outcomes.

5. Who, what, when, and where?

Consider the study population and methods. Results from one group or setting may not apply broadly. Pay attention to participant selection, inclusion and exclusion criteria, and whether the study’s variables match the question being asked.

6. Get both sides of the story.

If a new study contradicts established advice, look for expert commentary and additional reputable reports. Discuss the findings with a trusted healthcare professional before making major changes to diet, medications, or lifestyle.

7. Read the fine print.

Headlines are designed to attract clicks and may overstate findings. Read beyond the summary and examine the methods, limitations, and conclusions to understand what the study actually shows.

How Big Pharma Influences Studies

Another important consideration is the influence of large pharmaceutical companies on research, academic institutions, and healthcare professionals. Pharmaceutical firms fund many studies, sponsor educational events, and compensate physicians for speaking or consulting. These interactions can create subtle pressures that shape prescribing habits and research priorities.

Research requires funding, and companies with deep pockets can have an outsized impact. Awareness of potential industry influence helps readers evaluate findings more critically and recognize possible biases.

When evaluating claims about treatments or medications, remember that industry-sponsored research can be valuable—and in many cases advances care—but it should be assessed alongside independent studies and unbiased reviews.

Take a proactive role in your healthcare: read past headlines, review the original studies when possible, be mindful of confirmation bias, and remain open to new evidence while maintaining a healthy skepticism. This approach mirrors the scientific method and helps ensure decisions are based on the best available information.
