All Seshat codes go through an iterative process of editing and review before being used in analyses submitted for publication. For each variable, the initial value coded by RAs is later checked, edited, and augmented by Seshat experts, then reviewed by a Data Review Board (DRB). The latter comprises the senior team responsible for data management on a given paper, generally consisting of a combination of humanities scholars (e.g. historians, archaeologists, classicists, and anthropologists) and scientists (e.g. data analysts and complexity scientists). Typically, the DRB will include all members of the Seshat Board of Directors.
The DRB engages Seshat experts to review coding decisions, provide literature recommendations, and assist with the interpretation of complicated or conflicting evidence. When Seshat experts point out disagreements in the literature or disagree among themselves on a particular code, this is recorded so that multiple analyses can be run taking into account contrasting interpretations. The DRB scrutinizes all initial coding decisions and may request further expert review, where appropriate, to address remaining points of uncertainty. The DRB is also responsible for ensuring that coding conventions are consistently applied across NGAs and by all Seshat RAs. The DRB is ultimately responsible for the data presented in published work.
