But if we look at what we have now, which may change, but I doubt it, it shows a very small, but still existing, connection between introversion-extroversion and the good-evil alignment of factions.
More precisely, this means that introverts are slightly more likely to "prefer" evil fantasy factions, while extroverts, conversely, prefer good ones. However, temperament accounts for only about 6% of the overall reasons why people choose one side or another in fantasy. This is very little. But, interestingly, this percentage is present.
Unfortunately, there is nothing else to say about the relationships.
