Today there are tools to objectively determine whether the recent resurgence of nationalist and xenophobic attitudes in many countries of the world is evidenced in an objective manner, and whether it causes adverse consequences in the state of public mental health. The estimation of such changes can be made, for instance, by tracking changes that are recorded in the annual reports of the ‘World Justice Project’ (rule of Law Index) .It is possible to formulate remedies to counteract the deterioration of public mental health.Although the reasons for the intensification of nationalist and xenophobic attitudes are very complex, the counteractions for these changes in social consciousness can be underaken not only by enlightened publicists and politicians but also by people who are concerned about the state of public health. They can refer to the methods of so-called positive psychology and positive psychiatry and widely known famous and reputable cultural products (movies, novels, mass media performances).Development and implementation of the methods and tools influencing the whole population, which counteract spreading xenophobia is a new challenge for the people who care about the state of public health.
