The economic theories propose that people make their decisions rationally, practically avoiding the risk. Nevertheless, where could be then ranked gamblers, bookmakers and similar people? They are not just a negligible statistical deviation. On the contrary, there are many of them among us. This paper presents some of demonstrations that are different view on making decisions.
