I mentioned this before, but I'll say it again. As far as I know these are the available traits:
Pragmatic vs Romantic
Altruistic vs Egotistical
Independent vs Obedient
Righteous vs Renegade
Bold vs Timid
Compassionate vs Heartless
Forgiving vs Vindictive
Spiritual vs Materialistic
An AI personality is probably going to be made up of a single assigned traits from each of the above eight rows, which in turn will determine how your AI-controlled person responds during conversations.
Yeah, now, while I don't know how Larian is doing it, with the opposing traits, it seems to me that one way they're building those personalities could indeed be by selecting which trait (A vs B) they prefer for all of the traits.
It's possibly slightly more complicated, as there could be a third option: "Prefers A", "Prefers B", or "no preference" for cases in which the personality has no strong opinion one way or another. Those cases would be resolved via internal coin flip.
BUT, if it were REALLY so simple as this, then Larian shouldn't have had much trouble making them, which suggests that something more complicated is happening behind the scenes.
