Prejudice has always been part of life whether it be religious persecution, female repression or racism, and the death of George Floyd has highlighted once again the question of oppression around the world.
CGTN's The Agenda with Stephen Cole takes a look at what sparks prejudice and why the thought process goes wrong.
Prejudice is a premature judgment - where someone makes a decision on a person or an issue before they have all the information.
It is a natural process so that people can make an immediate overall view of a situation. Sub-consciously people put others into categories like gender, race and religion.
Humans are social animals and our identity comes from the groups that we belong to or would like to belong to but these snap decisions on others are of course not always right. It leads to stereotyping and prejudice.
The results can be inequality and isolation but while it is a natural process there is a school of thought that it doesn't need to be the case. Professor Iyiola Solanke, of the University of Leeds, believes that it may be possible to cure prejudice by treating it as a virus.
