This will be an incomplete post because I am tired. I just did not want to lose this information. I remembered this idea that I forgot weeks ago, when I was reading a review about a new television show that caught my interest called Defiance. I came to realize that all reviews are an attempt to impose one's opinion on others. They do not merely supply raw data but also interpretation. I had an interesting thought about a world where that was not possible. I am currently trying to understand what that world would be like to determine whether the power to control opinion is an inefficiency in human communication.
Update: I decided that this power is definitely not an inefficiency.
