Researchers focusing on cultural influences on personality have discovered that there are both, variability and similarities regarding personalities among cultures.
It is a fact that although people live in different countries, sometimes they are very alike. And we are not talking about race or ethnicity, but to the way they think and behave. That is why researchers focusing on cultural influences on personality realize that people from Spain and México are much alike in the way they behave and live their traditions. The same happens with Italian people and Mexican people. They are so much alike in family issues and the way they see life. It is impressive. Sociologists have found that being Latins, different nationalities share similar traits.
