In fiction we see a lot of alien lifeforms being cold and emotionless when making decisions because their minds are supposed to be more advanced. Some people have asked the question what the next step for evolution would look like in reference to the small differences between humans and chimps. For us to move a step up in the same way we moved a step up from chimps.

Thinking about this, though. It's possible that moving a step up in this way could make those beings more emotional and irrational. If their capability to experience emotion was elevated due to a more developed brain wouldn't it be possible that these beings would commit more atrocities than humans? Or even worse atrocities? Now, with a more developed brain one can assume that their ability to control their emotions or respond to their emotions would also be elevated but brains are complicated things.

If these brains were to develop in a way that allowed them to experience emotions at a more intense level then their mental illness would be much more extreme. Of course this is all assuming aliens have brains as their central processing unit.

I am writing all this because I am starting to think that humans may fall into a golden ratio of evolution based on our limited mental abilities. Also, to move further beyond the development puts that life forms species at an ever growing risk of self destruction.

I would really like to hear some thoughts about this because it seems like a fun discussion to have given our recent advances and aspirations for space travel.
