This chapter will clarify that the recent spread of populism is based on the fact that logical and emotional thinking/behaving are merging, especially in the West. In the West since the era of Greek philosopher Plato, people have tried to separate logic and emotion and have emphasized the superiority of logic to emotion. However, because of the invention and progress of media technologies, recently people's ways of thinking/behaving are becoming emotional. Therefore, the trend of populism could be understood that the people's ways of thinking/behaving in the West are approaching those in Asia. This phenomenon can be called “Asianization.” This means that populism is not a temporal trend but a long-time lasting trend. Also, this chapter will describe how to overcome populism.
