What is operationalization in physics?

Operationalization is the process of defining how to measure a phenomenon that is difficult to define directly. By linking abstract or latent concepts to observable and measurable effects, it provides a practical way to study them through empirical observation. This concept was originally introduced to research by British physicist Norman Robert Campbell in 1920, and it remains in use in physics alongside other fields.

What we know

• Operationalization defines a method to measure phenomena that are difficult to directly observe or measure because they are general, abstract, or latent. [2]
• The concept of operationalization was first presented by British physicist Norman Robert Campbell in his 1920 book Physics: The Elements and continues to be used in physics. [1, 2]
• Repeating an analysis with competing alternative operationalizations to check whether results remain unchanged is known as checking robustness. [2]
• Operationalization is utilized across physics, the life sciences, social sciences, psychology, and medicine. [2]
