Errors in choosing scales (nominal, ordinal, interval) are also a problem in digital international relations. Building any metrics within a study is tied to reference points that appear most useful.
However, such reference points do not always reflect an objective picture. This also concerns the use of existing indices or ratings that fail to capture all necessary aspects and sometimes present qualitative parameters as quantitative ones.
For example, a "soft power" index, if inconsistently designed, may include subjective indicators such as "government effectiveness," which in itself depends on other indices and (in the absence of explanatory tables or clarifications) is not directly quantifiable or may be distorted. This leads to unreliable conclusions about a country’s real influence in international affairs.
