What are the correlations between the facets of honesty-humility in HEXACO personality and the Dark Triad? I was just reading some of the items in the HEXACO measure of personality. It seems to me that the "honesty-humility" factor is actually more naturally expressed in the opposite way. I.e., about three quarters of the items are reverse scored.

For example, items measuring fairness (i.e., reverse coded) tend to focus on a willingness to engage in corrupt or even criminal behavior to advance your self-interest. Items measuring greed avoidance seem to be focused on concern with social status grounded in superficial things. Modesty items seems more like a measure of narcissism (i.e., believing you are better than others in some essential and vague way). Sincerity seems to have items concerned with a willingness to engage in social manipulation through flattery and guilt.

This got me interested in the correlation between honest-humility and the dark triad: machiavellianism, narcissism, and psychopathy.

What are the best estimates of the correlation between HEXACO honesty-humility (and facets) with the Dark Triad?
Lee and Ashton (2014) write:


  A few studies have directly examined the relations of the Dark Triad
  with the Honesty–Humility factor (as operationalized in the HEXACO
  Personality Inventory [–Revised]; HEXACO-PI[-R]). These investigations
  have found the low pole of the Honesty– Humility factor to be
  essentially identical to the common elementof the Dark Triad variables
  (Lee &amp; Ashton, 2005; Lee et al., 2013).


One study I found by Aghababaei et al (2014) reports the following correlations for 223 employees using 12 item dark triad and 60-item hexaco.


Of course, this is not the ideal study for facet-level measurement of honesty-humility. Ideally, you'd want more items both for facet-level measurement and measurement of each of the dark triad in order to get a broad and reliable measure. But it should give some idea.
