Selfish behavior
They can not think, yes, but the truth is that you are selfish. We all. However, selfish is not necessarily a bad thing, as in the true sense of the word, selfish means you can think, act and your own point of view.
For example, if you do not eat food, because you think that your friend sees hunger, or to believe that workers could work with a bite to eat. No, you eat because they are hungry, and so, you are from your own selfish point of view. Motivated by the desire to be a sense, change (eg hunger) to another (ie full).
Selfishness and manipulation of the media
Advertisers and the media know what the personality trait very good, and try their hardest to exploit. Ever messages such as “Are you overweight? Or” Are you currently in debt, “then do not hesitate to call us or to purchase these products, and all will be better magic!
OK, I am a little dramatisierend, but the basic principles are the same. In an advertisement is first and foremost a declaration designed to get your attention and get a sense in the context of this statement.
Controlling your actions by which control of your emotions
You will then submit a change of emotion, an emotion you prefer desirable. Example: You feel depressed about your weight, but you will see an advertisement for a fitness center nearby. They decided to acquire a participation in the gym.
Even if you do not use that membership of many, or even all (like most people who buy Memberships gym), at the time you purchased it feel even better about oneself to be done.
