A recent study found hormone-disrupting chemicals in menstrual products sold in South Africa.
The findings sparked dozens of headlines in the last week, along with panic, anger and questions around transparency. On social media, the results have at times been exaggerated or entirely misinterpreted.
In such cases, here's how you can cut through the noise.
1) Find the original research paper
It seems obvious, but start by reading the paper. Many key details, including limitations, are only found there. Guides such as those from the Open Notebook on reading scientific papers and long documents can help you break down complex studies into clear takeaways.
2) Is there causation or correlation?
Scientists are careful about making direct links – that event A causes event B, which is called a causal relationship. Scientists have to supply a lot of evidence to prove that one thing directly causes another.
Instead, they are more likely to say there was a correlation between event A and event B – that is, there is a relationship between the two.
3) Contact the authors
The paper should list the details of the corresponding or lead researcher. If you have questions about their findings, don’t hesitate to ask. Researchers can clarify what their findings do, and don't, show.
4) Be wary of sensational language
If a news article uses dramatic or sensational language, you might want to dig deeper. Words like ‘groundbreaking’ and ‘breakthrough’ can signal over-hype. It’s common to use emotive language to grab attention, but this can distort the research.
Remember that good science journalism should explain why findings matter and provide basic context, such as how the research was done and what remains uncertain.
