A man is extremely intelligent, thoughtful and among other, a very mysterious creature and therefore, he should be continuously observed. Until now, it was known how a consumer behaves and the affects on that behaviour. However, until recently, there was no word about ''why'' they are behaving in that particular way. There is a scientific experiment that went deeply into this field. It is about behavioral economics. Numerous experiments have shown a different perspective about human behavior and the most common mistakes that appear in conditions of uncertainty. Using psychological achievements, it enabled better understanding of subjects by explaining and seeing how they react in different situations. Certain subjects are finding the potential benefits of behavioral knowledge, using the techniques of encouragement, framing and anchoring, which is why the question of ethics is also a significant part of this work. With the research conducted, it can be proven that a common man can easily deal with the problems he is facing today.
