Stereotypes are a social product. In spite of being „politicly incorrect”, they exist and mirrors all hidden emotions and attitudes towards others. Also, they discover how „others” are evaluated. The comparison between ‚self-portrait’ and the pictures of the other nations is very instructive. The diversity is based on the point of view and perspective. The mentality of the social group creating the stereotypes is expressed by the language in many ways: in common opinion, jokes, nicknames, etc. The way we talk about other nations says a lot about us.
Have a look at the mapping stereotypes by the alpha designer. Were you surprised by the way your country was viewed by the others? I think the author has a fantastic sense of humour.
