Issue A fixed frame with a shifting indicator base does not make editions comparable

Summary

This issue concerns what the Global Opportunity Index can claim about change over time. The report says its overall structure and category framework have been kept unchanged since 2016 precisely so that results stay comparable. In the same breath it concedes that the indicators filling that framework have been revised as the conditions driving investor decisions shifted. The 2026 edition, for example, replaces Doing Business data and adds new digital-economy measures. What stays stable is therefore the container, not the scores or ranks it produces, so movements between editions may reflect changes in measurement as much as changes in countries.
