Agreeableness in the HEXACO

We see little benefit to separating Honesty-Humility from the broader FFM Agreeableness domain. In our commentary, we summarize several studies showing that although lexically-based Big Five measures under-represent H-H content, the same cannot be said for FFM-based measures. We also indicate that contrary to claims by some advocates, FFM-based Agreeableness is more strongly related to the Dark Triad than H-H. Finally, we review a recent study examining the lower-order structure of FFM Agreeableness that failed to reveal a separate H-H factor, despite more than adequate representation of that content.
