7. Ethics & Fairness in AI

Ethics & Challenges

Why AI Ethics Matters

As AI systems make increasingly consequential decisions — about hiring, lending, medical treatment, and criminal justice — ensuring they are fair, transparent, and accountable becomes crucial. Unethical AI can perpetuate discrimination, violate privacy, and cause harm.

Key Ethical Issues

Bias and Fairness

AI systems can inherit and amplify biases present in training data. Examples include facial recognition performing poorly on darker skin tones, hiring algorithms favoring men over women, and predictive policing reinforcing racial disparities.

Transparency and Explainability

Many AI systems (especially deep neural networks) operate as "black boxes." Explainable AI (XAI) aims to make model decisions interpretable to humans. Techniques include LIME, SHAP, attention visualization, and feature importance analysis.

Privacy

AI often requires large amounts of personal data. Concerns include data collection consent, surveillance, data breaches, and the right to be forgotten. Differential privacy and federated learning are technical approaches to mitigate privacy risks.

Accountability

When an AI system causes harm, who is responsible? The developer? The deployer? The user? Clear governance frameworks are needed to assign accountability.

Job Displacement

AI automation may displace workers in certain industries. Addressing this requires reskilling programs, social safety nets, and careful economic planning.

AI Ethics Principles

Major organizations have published ethics guidelines. Common themes include:

Regulation

The EU AI Act categorizes AI applications by risk level (unacceptable, high, limited, minimal). Other countries are developing their own frameworks. Regulation aims to protect citizens while fostering innovation.

Practice Task: Research a real-world AI bias incident (e.g., biased hiring tool, facial recognition failure). Write a case study describing: (1) What happened, (2) What caused the bias, (3) What the consequences were, (4) How it could have been prevented. Propose three ethical guidelines for a company building an AI hiring system.
