An arbiter is a person who has the power to decide what is right, fair, or best in a dispute or in matters of taste.
From Latin "arbiter" meaning "judge" or "witness," possibly from roots meaning "to go" and "to see." It originally referred to someone who sees both sides and makes a decision.
When we call someone an “arbiter of style” or “arbiter of truth,” we’re handing them quiet power over our judgments. The word reminds us that a lot of what feels “obvious” was decided by some arbiter we chose to trust.
Historically, arbiters and judges were overwhelmingly male due to legal and political exclusion of women from formal decision‑making roles. The term can also appear in phrases like "arbiter of taste" that have often centered male critics and gatekeepers.
Use gender‑neutral language around the role (e.g., "arbiter" or "decision‑maker") and avoid assuming the arbiter is male; specify gender only when it is relevant and known.

When discussing the history of arbitration and adjudication, note the contributions of women judges, mediators, and legal scholars who entered these roles only after formal barriers were removed.
