The personality differences between right vs left tend to be about maintaining social hierarchies vs freeing people from them (most effectively by generating new ones). You need both because no social hierarchy can fully account for the reality (or hyper-reality) it is in and needs to be challenged to adapt to the ever-changing landscape. You need maintenance of social-hierarchies, because mostly they are quite effective at generating the most positive outcomes for the largest number of people (at least at the point when they were generated). Reiterating my comment in another sub-thread: It looks like TIV might be maladaptive because it is highly correlated to anxious-attachment styles, which usually results from poor childhood attachment. Someone with a very healthy attachment-style is unlikely to suffer from TIV (according to the paper). That being said, even individually maladaptive personalties can be adaptive for their social contexts, because if a social-hierarchy starts to generate a lot of victimhood that is probably a strong signal to healthy members of that social-hierarchy that the hierarchy they are in is generating too many negative outcomes and needs to be corrected somehow.
