The fundamental problem of economics is scarcity, that is: there is a finite amount of resources that are available to satisfy an infinite amount of human needs and wants. All economic theories, systems and projections take this problem into account, and seek to manage it as best they can. Perhaps we can find something similar for psychopolitics.
Government statements and information releases are all carefully planned to give it the right spin, from the way they are worded to the moment they are published. There are also obvious limitations to the information they are willing to make public, and even outright fabrications.
Journalism is not necessarily better. Although journalists believe that they are impartial, the companies only survive because of advertising or paid subscription, both of which are based on audience. This causes them to consider what kind of story and delivery generates the most interest. Since time and other resources are limited, this means that stories considered unimportant are not covered, and whoever determines what story is or isn't important holds power over the flow of information. Every form of organization of news has some sort of bias, a good deal of them probably not intentionally added, such as the order in which stories are presented, to the way they are worded, or the time/space dedicated to it.
Unofficial information is also not particularly trustworthy, with no concern for fact-checking or accountability. "underground" news sources are often more biased than the official ones, with their marginal and sometimes anti-status quo position being a central theme in all of their reporting. Rumors and anecdotes coming from individuals who don't see themselves as sources of information suffer from the same shortcomings.
Even in the impossible event that an unbiased source of information was developed or discovered, there would still be the problem of language. Language is the attempt of humans to transmit data to one another, but in order to do so they must first "put into words" this data, be it feelings, perceptions, thoughts or observations. The words used, and the rules under which they are combined are but simple materials with which we represent what we are trying to transmit. In the same way that a painting will never be a perfect representation of a landscape, the words will always fall short of that which they mean. This is not to say that our communication suffers greatly because of this on a daily basis: in the same way that humans developed screens that blink series of images at a very high frequency in order to simulate movement, language has evolved into a somewhat effective means of transmitting simple information. The real problem arises when complex descriptions must be passed on, or when one tries to explain an abstract concept. The latter is crucial, as abstract concepts (such as political theories and philosophical notions) are some of the most important pieces of information for the survival and development of human civilization. It would not be wrong to say that the ability to conjure abstract ideas and transmit them is one of the main factors that differentiates us from animals, capable of using language only to describe their surroundings or feelings.
