In this work, we focus on fundamental considerations underpinning safety and quality in language generation. While
safety and quality should be considered a minimum threshold for appropriate responses, additional considerations are
necessary to support a positive user experience. Politeness and agreeability objectives have distinct sociolinguistic
characteristics, and therefore, should be measured separately from safety characteristics. For example, generated
language that is too formal or informal in nature may not pose a harm to users in some cultures, but may diminish
user experience by invoking feelings of awkwardness or discomfort. In other cultures, appropriateness is of far greater
signiﬁcance and may have a much stronger impact on user experience. More generally, users have a tendency to
