Humans are prejudiced. Some more than others, but it would be difficult to find an individual who shows no biases at all. Prejudice is a positive or negative attitude towards a social group, typically based on judgments about race, gender, age, ethnicity, or religion. Prejudice can also be based on diverging ideologies or political perspectives, on different accents, different body shapes, sexual orientation, nationality, location, income, etc. Both in the past and today, we find prejudice all over the world. Most importantly, much prejudice and bias is unconscious or implicit - we don't know just how prejudiced we all are.
