Mind Reading Societies

This article also appeared in Science In My Fiction

A common characteristic of “advanced races” in science-fiction is the ability to communicate without using speech, gestures, or writing, but with their brains. Telepathy can be an inherent ability powered by “magic”, or it can be granted by implanted radios. Though one has to wonder what kind of effect this has on their society, specifically relating to their ability to keep secrets or to deceive one another.

Some say that relationships, and by extension civilizations, are founded on lies and held together by secrets. I expect that would be very hard if everyone could read everyone else’s minds. If such a society existed they would either have to be completely honest and keep no secrets from one another; or they’d make scanning another’s thoughts without permission a serious taboo or crime. In fact, one might expect a naturally telepathic species to be colonial organisms.

And as for collective consciousnesses, most portrayals involve each member broadcasting their every thought to everyone else in the collective, unless they’re all remotes controlled by the queen of course. This shouldn’t be a problem if they are all born into the hive like ants are, but if they were individually sapient beings (such as humans) who joined together as adults their individual pasts might come into conflict. If, for example, a married couple were to join such a group mind would it bring them closer, or tear them apart?

Some possibilities for writing:
• Humanity encounters a telepathic alien race that can only read each other’s minds, human brains are closed to them except through conventional communication. They have no concept of deception and cannot tell when humans are lying to them.
• In the near future brain-computer interfaces are ubiquitous and allow full thought-to-thought communication between two or more people. Someone develops a program similar to Twitter except that it posts thoughts instead of short texts.
• Software that allows constant mental communication between multiple people is developed and becomes the next big thing, followed by a surge of divorces and violent crime.

Aliens, psychology by diet

When we expand into outer space, we may contact other sapient species, and it can be guaranteed that they will think differently than us. But we may be able to predict their behavior by their diet. Something that Larry Niven touched on with the carnivorous Kzinti and the herbivorous Puppeteers.

Carnivores: The first thing you should remember is that predators are opportunists, they always take the route that is least expensive. If they get to colonizing other planets I would expect them to have the capability to adapt considering their need for complex ecosystems that would be a hassle to terraform from scratch. Due to their opportunistic natures I doubt that they might go to the trouble of eating other sapient species like us humans, though if there is a massive technological difference they might enslave or domesticate the less advanced species. Relations with humanity would probably be neutral or even allies, we might colonize and terraform dead worlds while they adapt to living ones.

Herbivores: To an herbivore, any other animal is a potential enemy, a predator or a competitor. I expect that their planets would be ecological disasters devoid of any other animal species except in the most extreme regions they never got around to colonizing. Since their supporting ecosystems would be comparatively simple they would probably terraform their colonies, because of that I expect that they would use a lot of weapons of mass destruction in inter-species wars. In addition the fact that extreme paranoia would have been a survival trait in their early history (more than humans anyway) would make diplomacy with them very difficult.

Omnivores: Would probably be closest to humans psychologically, as we are omnivores ourselves. Kind of a wild card, they might terraform, they might adapt, they might exterminate, they might enslave. They might even join forces with us and form the galactic federation. Fortunately trends on earth make it seem like most sapient species will be omnivorous.

Plants: I don't see any reason for plants to become sapient, but maybe a machine civilization would be similar. In short, they wouldn't care about consumers unless we got in their way.
