This, to us, weird callousness when it comes to other people losing property or even their lives, really does make it seem like she doesn't fully grasp that other people, billions of them, are just as real and multifaceted (as in - with aspirations, hopes, fears, love for others) as her.
Stuff like Covid-19 happening in the US (but also globally ofc.) being somehow tied to her god looking out for her not getting evicted, or that a hurricane tearing through Null's old area being a "messenger" or something - It genuinely makes me feel like she has some personality disorder that was never diagnosed, beyond just delusional grandeur. Then again, it might have been diagnosed and she just never acknowledged it. That aside, there is an "ability" (I am not sure that can be considered the proper word though) I am just not seeing here.
There is a term known as "Mentalization" that has been adopted more and more over the past 2 decades by various schools of psychology, initially to find new ways to help people with Borderline Personality Disorder.
It's essentially our ability to understand our own feelings and those of others properly, in a social context - your level of ability to mentalize is essentially how well you can recognize and interpret the complex state of mind and consequently the motivations of others (as well as yourself) correctly. This isn't just empathy. Empathy is feeling with someone else - You see someone cry, you might feel a portion of that sadness.
Mentalization however, is recognizing and dealing with it correctly in others as well as oneself. It is an essential skill, usually developed during early childhood and honed, trained and refined through socialization as we grow up.
Obviously everyone can see how this is important - if you see a person grinning and you are poor at mentalizing, you might immediately assume wrongly, that that person is ridiculing you. You might then assume that person is laughing at you maliciously. You might then assume that this maliciousness might translate into real, malicious action against you. Consequently your reaction might negatively influence the outcome of that situation.
You might make all these assumptions, even as you observe the person looking at their phone a moment before - which means they may have just read a funny message before looking up in your general direction. This is one side of mentalization, recognizing the complex state of mind of others and then adjusting our state of mind based on it.
The other side is then, introspective. Say that all the evidence, to me, points to that person grinning at me maliciously (because I'm in a bad mood and I didn't see them checking their phone). Someone who can mentalize properly internally (or recover from lapses in mentalization), will then categorize this in a healthy way. Perhaps they will see that their assumptions could be flawed, due to their mood. Perhaps they will realize that people grin all the time and it is therefore not relevant, or related, to them. Or, even if it WAS directed at them, it is a perceived slight that can easily be overlooked and ignored (in fact, overlooking it might be the best course of action overall - who cares who grins at whom). Thus, good mentalization is a shield against paranoia, unwarranted fear and anger.
Consequently, even if one's initial assumption (malicious grinning) is wrong, one's acute mentalization can still cause a positive outcome. It is pretty much a MUST, for any long term relationship, big or small, between someone as close as a spouse or as far as a bureaucrat, to work properly. Because misinterpreting the motivations of others and thus reacting in a manner utterly surprising and unfitting (to the other party), is a basic recipe for interpersonal disaster.
Sorry for the monologue / psychsperging, but you guys can probably see why I find this concept worth mentioning here.

Or really anything by those two, 's basically the only subject they get published on.
