What do you understand by prejudice? Explain with the help of an example.

Prejudice is an unfavourable view or assumption that is formed without knowledge, reason, or justification. It is a judgement or opinion formed without knowing the facts, particularly against an ethnic, racial, socio-economic, or religious group.

Example: An AI system is designed to predict the chances of diabetes. If the data is collected by assuming that obesity leads to diabetes, the data may include only the weight of people and ignore other factors such as family history, blood pressure, anxiety, etc. In this case, the prediction generated by the AI model will be wrong in most cases due to prejudice in data collection.
