One of Adam Grant's articles linked in the WBW post had a link to
HEXACO, which is a personality test that's far better-supported by science and research. Just took it, and I'm in the 90th percentile in Honesty-Humility, 10th percentile in Emotionality, close to but just below the median on eXtraversion, high in Agreebleness, a little low in Conscientiousness, and somewhat high in Openness to Experience.
