Agreeableness is considered to be a superordinate trait, meaning that it is a grouping of personality sub-traits that cluster together statistically. The lower-level traits, or facets that are grouped under agreeableness are: trust, straightforwardness, altruism, compliance, modesty, and tender-mindedness.[6]
