This study presented a new perspective on social choice by employing anonymity measures. While anonymity is generally regarded as a positive condition for ensuring the quality of social choice outcomes, it is primarily equated with the concept of the secret ballot. Today, however, anonymity has begun to be viewed as a continuous concept — a matter of degree rather than a binary attribute — particularly in computer science. On the other hand, in social choice theory, anonymity has been deeply discussed using precisely defined logics. This formal definition, however, focuses on equality among individuals, leaving privacy concerns outside its scope. This study focused on anonymity as privacy in social choice and explored the social impact of this contemporary viewpoint regarding the levels of anonymity. From this new perspective, it seems to be appropriate to regard the maintenance of anonymity levels as a fundamental human right. This shift in perspective could have a profound impact on conventional social goals, including the Sustainable Development Goals (SDGs), which do not explicitly address the topic of individual privacy.
