Index numbers for social issues need to be impartial by design
The recent interest in index numbers has raised questions about their usefulness and validity. The history and principles of index numbers are discussed, highlighting the importance of a clear theoretical framework, adherence to data quality principles, and transparency. Recent examples of indices related to hunger, press freedom or democracy are criticized for their reliance on 'expert opinions' and 'preference surveys', which can be manipulable and lack transparency. Poorly constructed indices risk discrediting the entire discussion on important social issues.
