Jordan Peterson addressed this question often as well. Haight was a frequent guest on his podcast.
Peterson often used the OCEAN measure of personality traits:
- openness (O) measures creativity, curiosity, and willingness to entertain new ideas.
- conscientiousness (C) measures self-control, diligence, and attention to detail..
- extraversion (E) measures boldness, energy, and social interactivity..
- agreeableness (A) measures kindness, helpfulness, and willingness to cooperate..
- neuroticism (N) measures depression, irritability, and moodiness.
These categories are not moral judgements - being "open" and "not open" both have advantages and disadvantages.
The modern artist, for example, may be high in "openness" which might stimulate creativity, but they may also lack conscientiousness, which could make them difficult to manage money or live long-term with partners.
They talk a lot about how creative they are, but you’ll know them by their fruits.
Stephen King hasn’t written a significant book in decades.
How’s George RR Martin doing with that Game of Thrones book?
Hollywood is churning out nonstop remakes, sequels, adaptations of existing IPs.
Do you have a link to JP and JH talking about moral foundations theory?
What makes JH different is that he found these trends throughout existing cultures and found they roughly correspond to differences in male and female outlook.
