One of the most indispensable social competences in today’s world is an ability to communicate with representatives of other cultures. The ability, based on tolerance, understanding and respect, transforms into an intercultural dialogue which is essential in the process of integration between nations, races and various minorities. However, stereotypes, biases and intolerance seem to be the main obstacles in the dialogue. Young people should be particularly well prepared to the intercultural dialogue. Thus, it arises a question concerning students’ intolerance. Which manifestation of otherness makes the students intolerant? Research, conducted in PWSZ in Legnica in 2008 and in WSZ „Edukacja” in Wroclaw in 2016, demonstrate that biases and intolerance towards minorities are still strongly embedded in students attitudes, as far as social life and work are concerned. It makes the students education towards intercultural dialogue more essential.
