People like communicating with each other to
exchange information, sometimes they exchange information for their own serious
purposes, or they exchange information (or gossip) merely for entertainment
purposes. Both kinds of purposes are completely fine. Information is almost
starts of everything. Technology is developed in labs or offices, the
information has to be passed from labs or offices to factories in order to
produce hi-tech products. The information has to be passed from traders
to brokers in order to make stock exchange happen.
Information is a very important concept in the
game theory. A game's outcome can be very different between a setup with
communication and a setup without communication. Although people may not
tell truth, as they may strategically lie to other players in order to get more
profits, people can predict others' strategies, especially when we expect all
people work for the best of their interests. Moreover, when people communicate
with each other, they are exchanging very complex information including
people's emotion and some unexplainable expression as well, these kinds of
information are difficult to be modelled, and also important when people are
making their decisions. People do express their emotional feelings; therefore, it
is reasonable for people to receive emotional expression as part of information
they receive, though it is not sensible in the eyes of economists.
Overall, people
are exchanging information all the time in all different forms. Some form of
information is very complex and almost impossible to be modelled, such as
emotion, but plays important roles in our decision making.
