Behold! After a few days of contemplating what I said in the Ancient Aliens post – you know, about how alien’s technology and moral capacity are often interrelated in sci-fi – I realized I needed to put it into graphic form. And as I said in that post, if we are to consider technological advancement as one axis and level of benevolence as another, then the outcome would look something like this:

The design is based on the Zombie graph that’s been floating around the internet for some time. There, the designer placed different Zombie movies based on two criteria: intelligence and speed. In much the same way, I’ve designed a graph for aliens that is based on two similar criteria: technological advancement and level of friendliness.
I selected aliens that I thought best represented the range of development and behavior in the sci-fi genre. I also included as many franchises as I could think of, just off the top of my head. I certainly wasn’t scientific about it, just relative and to the best of my abilities. And when I was done, I noticed an interesting pattern…
Hostile/Advanced Aliens Rule!:
For example, notice how the vast majority of races from your well-known franchises (Star Trek, B5, Stargate, Star Craft, AvP, Halo, etc) fall into the upper left quadrant. This is the area where malevolence and technological sophistication combine in varying degrees. By contrast, the second largest concentration of races occurs in the advanced/benevolent quadrant, again to varying degrees. Almost no races fall into the nascent (i.e. primitive) quadrants, be they hostile or gentle.
On the one hand, the Xenomorph from Alien and the Arachnids from Starship Troopers both fell into the technologically backward category (technically), and were both classified as malevolent because of their innate hostility to foreign organisms. The Na’vi, from Avatar, were the only alien race that fit the bill for technologically nascent and benevolent. I’m sure there are plenty of examples that could stack this analysis in a different way, but like I said, this was off the top of my head.
The Zerg, I have to admit, were a bit of a conundrum for me. While they are technically a race that does not employ technology per se, they are highly advanced in terms of their biological evolution, to the point where they rely on specialized creatures in the same way that humans rely on machinery. But then again, that’s all for the sake of ensuring that the different factions in the video game are evenly matched. It’s not meant to be a realistic assessment. Much the same is true of the Xenomorphs. While they do not employ tools, fly around in spaceships, or use guns, they are nevertheless an extremely evolved organism that is capable of besting humanity in any contest.
And just to be clear, the middle point of the graph (0,0, where the axes meet) is where humanity stands now in terms of moral behavior and technological development. Sure, some say we’d fall into the evil quadrant, but I tend to believe that humanity is morally ambiguous, neither too good or too evil. Where aliens fall into the spectrum in most sci-fi franchises is meant to reflect this. Much the same is true of technological prowess, where aliens are classified as “advanced” or “primitive” solely in comparison to ourselves.
This all might sound anthropocentric, but that’s the point, isn’t it? These are stories written by human beings for other human beings. All the references, symbols and measuring sticks come from inside us. So in the end, aliens themselves, as represented in our best science fiction, also come from inside ourselves. Their values, their tools, and even their appearances are all constructs of what is familiar and accessible to us. In short, they are merely tools with which we measure ourselves, both morally and technically.
Conclusions:
Well, right off the cuff I’d say the reason we prefer our aliens hostile and advanced is because it makes them seem more threatening and scary that way. Clearly, this makes for a more interesting story. While an alien race that is kind, innocent and backwards can make for an effective tale about the evils of colonialism and imperialism and how one can easily find themselves on the side of evil, these seem to be fewer and farther between. I’d say this is most likely because moral allegories are less intriguing than action dramas. Or maybe just prefer to think of ourselves as the good guys. Let someone else serve as the allegory for evil, selfish and runaway imperialistic behavior!
In addition, there’s the very real possibility that humanity will be making contact with an intelligent life form at some point in the future. And when we do, it’s likely to be the most awe-inspiring and frightening of experiences. When it comes to the unknown, ignorance begets fear and we prefer to err on the side of caution. So it would make sense that whenever we think of aliens, even if its just for the sake of fiction, we would naturally prefer to think of them as both learned and potentially hostile. If indeed aliens serve as a sort of projection for humanity’s own thoughts on itself, than pitching them as potentially hostile beings with advanced technology represents our own fear of the unknown.
In any case, if there is life out there, all these questions will be resolved in the distant future. Hell, maybe even the near-future. If some theorists are to be believed, aliens have already made contact with us and might even be walking among us right now. Granted, most of these people are hanging around the 7/11 with tin foil hats on, but they can’t all be crazy, right?
ewoks?
