Ethnocentrism negatively judges other cultures based on one's own cultural standards. Examples include Asians viewing Western eating utensils as unnecessary and some attributing siestas to laziness rather than considering climate factors. Extreme ethnocentrism, like Nazi Germany's beliefs, makes harmful assumptions about cultural superiority and inferiority. Less extreme forms include taking one's own culture for granted without considering others and focusing education only on developed Western countries and traditions. The most progressive approach embraces cultural diversity and exchange of ideas.
