Theories of Justice
Also known as theories of justice / what is justice
Ask three friends to split a pizza 'fairly' and you get three answers: equal slices, bigger slices for whoever's hungriest, or biggest for whoever made it. That single disagreement sits under every fight about tax, welfare and punishment. It decides whether an AI handing out loans or bail is 'fair' when it treats people differently (Machines That Learn, Technology), and it drives the wider debate about right and wrong online (Technology Ethics and the Digital Society, Technology). It is also the core question in healthcare (Healthcare Systems & Access, Health): should a scarce organ go to the sickest, the youngest, or whoever asked first?

- Is the justice system truly equitable for all?One view: The justice system aims for impartiality through laws and procedures, ensuring everyone is treated equally under the law. · Another: Systemic biases, socioeconomic disparities, and unequal access to legal resources often lead to unequal outcomes for different groups.Open question
- Should victims have a direct role in sentencing decisions?One view: Victims' perspectives are crucial for acknowledging their suffering and ensuring sentences reflect the full impact of the crime. · Another: Sentencing should be based on legal principles and evidence, not emotional responses, to maintain fairness and consistency.Open question

Where this connects to other fields — and why it's worth knowing.
- Artificial Intelligence & Machine Learning Technology
When AI predicts things like who might reoffend, people demanded it be 'fair.' But mathematicians proved something wild: you literally cannot satisfy every reasonable definition of fair at the same time. So building 'fair' AI forces a hard choice about which kind of unfairness you're willing to keep.
- Technology Ethics & the Digital Society Technology
People argued forever about what 'fair' means, then math ended the debate badly. You provably cannot build a risk score that is equally accurate and equally error-prone for every group at the same time; you must sacrifice one. A dorm-room philosophy fight became a cold theorem that no clever coder can dodge.
- Healthcare Systems & Access Health
When a new drug costs a fortune, someone has to decide who gets it. Health systems actually put a price tag on a year of healthy human life, then do the math. So the huge, misty question 'what's fair?' quietly turns into a number in a spreadsheet.
