We all sometimes disagree with others about the things we see in the world around us, and experience things at odds with our present understanding. Science aims to explain the things we experience so we can reach understanding and agreement.
The scientific method is the series of steps that all scientists should follow. By following these steps correctly, scientists ensure their results are not affected by external influences such as their own or others’ prior beliefs.
The steps in the scientific method are:
- Observation or idea
- Hypothesis
- Experiments to test hypothesis
- Peer review
- Publication
- Replication (typically by other scientists).
It is important to question whether the scientific method has been followed when news stories draw attention to the latest miracle cure or health scare. For example, if a scientist publicises their work directly to the media rather than through a peer reviewed journal, their results should be treated with caution.
At Vodafone, we only consider the opinion of panels commissioned by recognised national or international health agencies such as the World Health Organisation. Their opinions are based on the entire body of evidence, rather than on the basis of single scientific studies.
