Pretty much everything on the topic by Dr. Ramani (Here's her YouTube channel) is worth looking at. I recommend starting here. She has also published a couple of books on the topic which are also good, and generally consolidate a lot of what she has on other platforms in one place, though her most up-to-date thinking on the matter will pretty much always be on her YouTube channel and podcast. Here's her website so that you can find everything else. If you read any of her books, "Don't you know who I am?" is probably the most relevant one here.
What you'll get from her is mostly information on the nature and behavior of narcissists themselves. The primary value of this information is that you'll be able to spot narcissists and narcissistic behaviors way more easily (and thus, way more frequently) than you would otherwise be able to. We've been culturally conditioned to ignore or even justify a lot of narcissistic behaviors, so learning about them is a big eye-opener for seeing just how prevalent the problem is. Simply being able to recognize narcissistic behavior for what it is will go a very long way in helping you see things from my perspective.
You can also talk to me about this kind of stuff if you want. The intersection of narcissism and politics/economics is something I spend a lot of time thinking about. I actually can't point at anyone else on the internet who is writing about this sort of thing.
I believe that this is actually the case. There are plenty of studies showing strong correlation between political ideology and personality traits. In my personal experience, I've yet to meet someone with authoritarian politics who was not also lacking in empathy more generally.
I think that there is even more to it than that, though. There is a really interesting anthropological perspective on this to be had, where we can actually cast the development of authoritarian styles of governance as an expression of narcissism.
When we look at the actual timeline for the emergence of civilization, we see agriculture, then violence (increasingly organized as time goes on) then governance structures that resemble modern states. This is an account of the development of violence in northwestern Europe to help establish that timeline. That paper also cites other papers about the history of violence in other regions. Contrary to the popular narrative (thanks Hobbes /s), we don't actually see much evidence of violence at all prior to the development of agriculture. It is important to note that agriculture was developed about 40k years ago in response to a major worldwide drought that lasted about 1k years. (I would recommend reading "Civilized to Death" by Christopher Ryan for more on this topic.) Most sources arguing that pre-civilized society was terribly violent points at societies that existed in the 20k years between the development of agriculture and the emergence of modern-ish states (which, in some cases, were terribly violent). The traditional narrative about civilization and war would put the emergence of states before the invention of organized warfare, arguing that warfare was a response to the increasing complexity and scale of the conflicts that arose from the increased societal complexity of states. Archaeological evidence refutes this, so what gives?
There's more that makes this weird. We also know some things about how pre-civlized societies handled narcissism. Surprisingly often, these societies actually had a dedicated word for these people. The exact translation and connotation of the word varied from one population to the next, but the stories that they told were basically the same. (For reference, we learned this by interviewing members of indigenous societies that had not yet been heavily influenced by civilization. Some of these societies still existed as recently as a century ago - now there are almost none left.) These were the people who were 'unteachable', 'lazy', 'troublemakers' - they caused drama while contributing next to nothing. When these people didn't improve their behavior (or they did something heinous like commit murder or rape), they were exiled or killed. (Check out literature on 'rape-free' societies if you want to read more about this.) These individuals were pretty rare - around 1% of the population - so what little violence was necessary to keep the peace would not account for the evidence that we see from post-agricultural societies. We've no reason to believe that these pre-civilized societies suddenly stopped policing themselves when they were pushed into agriculture by the drought (and there's even some evidence that they did not - again, see "Civilized to Death"), yet the vast majority of us now live in a society where such a penalty for mere narcissism would be unthinkable.
Here's what I speculate happened. After settling down for agriculture, exile stopped being as lethal as it would have been before. Exiles could practice agriculture on their own and survive, when they wouldn't have been able to before (due to lack of technology, mostly). Also, stationary groups with fields that they can't watch literally 100% of the time and stores of food (they wouldn't have been storing much food prior to agriculture) are much easier to steal from. As such, we started to accumulate a population of these narcissistic individuals. These individuals are inherently self-centered and lazy. If they settled together (which they would have been incentivized to do, for many reasons), they would inevitably try to dominate each other in an attempt to gain power and status and the ability to exploit the labor power of the other exiles for their own personal gain. They would actually have a chance to learn ways of sneaking into other societies and hiding their toxic behavior with clever words. They could actually start working together as a violent force to bully whole other groups into submission, or even claim control of an area. Incidentally, we actually have some evidence that this sort of thing happened pretty early in the game with a riverhead and a group of bullies demanding tribute in exchange for access. These riverheads were an important source of easy food thanks to the salmon that would swim up there to reproduce, so this was a big deal. Here's an interview with an anthropologist who talks about that.
Naturally, these narcissists aren't very good at maintaining power over each other or their less-narcissistic peers in the beginning, but as time progresses, they would get better and better at it. They'd learn to pit different groups against each other so that no one group can get large enough to overthrow the minority that holds power (+ the other still-loyal groups). They'd learn that growing their population as fast as possible gives them a major edge over other societies, as it is far easier to bully other groups into submission when you outnumber them. Pretty much every major development in human history related to governance and economics gets cast in a new light with this perspective. Money becomes an ingenious solution to the problem of redistributing tribute/favors to one's cronies in order to keep them under control. The state monopoly on violence is the perfect hypocrisy for protecting one's own power with force while denying anybody else's right to do the same, regardless of where the threat to their power comes from. Not only does this allow you to crush any direct rebellion before it happens, but it also allows you to interfere in the development of various political groups, allowing you to maintain control over the entire political playing field. Capitalism becomes a brilliant way of taking power away from more rigid power structures like the church or the throne without needing to foment a violent rebellion.
A few other fun things result from such a narrative. The cause of sexism and the general disrespect for the rights and intelligence of children becomes obvious. Since all power ultimately comes from the use of force, women and children are at an inherent disadvantage compared to men due to their smaller size and lower physical strength. Forcing women to be breeders for that sweet sweet population growth was also a major contributor to their objectification. Agriculture was hard work, and the narcissistic men didn't want to do it, so their wives/children became de-facto slaves. (Note: Slave labor would not have existed prior to the development of these narcissistic societies.) Religious and racial discrimination is fundamentally about preventing foreign powers from interfering with local affairs, while also providing a convenient justification for using those out-groups as additional sources of slave labor. Also, we realize that literally no form of governance that has ever been invented since the development of the state has ever been designed to actually serve the people. They've always been various forms of compromise designed to consolidate and maintain power for the few while preventing the many from organizing a competent rebellion. The only form of governance that has ever existed to serve the people is anarchism, in the form of the aggressive egalitarianism practiced by pre-civilized societies. This isn't to say that we should go back to doing things exactly like we did in the stone age, but it does turn a lot of long-standing cultural assumptions about the nature governance and modern society on their head.
I could keep going, but I'll stop for now. This perspective is a real mind-bender, but way too many things fit into place when you think about history this way. It also makes sense that authoritarianism would be an invention of narcissism generally if authoritarianism was simply the political expression of narcissism on the individual level.
