Fairness is the concept in sociology, law and generally in society, that something should be equal and not be a contradiction to accepted standards. It's related to justice in both the legal and sociological sense. Fairness is also treating others equally or in a way that is considered right or reasonable. Fairness can mean sameness where everything is kept equal by being the same. Fairness can also mean "deservedness" meaning a person gets what they deserve. People who are successful by working hard get what they deserve. People who are lazy and do not work hard get less. Fairness can also be based on need. Those who have more should give more to help others. This is based on the concept that people have obligations to each other. Judges, lawmakers, referees and teachers are among those expected to be fair in their decisions. Fairness is keeping decisions free from any form of discrimination.
