AI Ethics Foundations

Ethics is the foundation of responsible AI. While regulations like the EU AI Act set legal minimums, ethical AI practices go beyond compliance to ensure AI systems benefit society and respect human dignity.

Why AI Ethics Matters

The Power and Peril of AI

AI systems increasingly influence critical decisions:

• Who gets hired or promoted
• Who receives medical treatment
• Who gets approved for credit
• What content people see online
• How communities are policed
• Which students get educational opportunities

The Stakes: AI decisions can amplify human flourishing or human suffering at unprecedented scale.

Beyond Compliance

Legal ≠ Ethical: Something can be legal but unethical.

Example: An AI system that legally maximizes engagement might unethically promote harmful content, exploit psychological vulnerabilities, or create filter bubbles.

Ethical AI: Considers broader societal impact beyond legal requirements.

Core Ethical Principles for AI

1. Human Dignity and Rights

AI must respect fundamental human rights and dignity.

Principles:

• Recognize the inherent worth of every person
• Protect human autonomy and agency
• Respect privacy and personal data
• Prevent discrimination and bias
• Enable meaningful human control

Implementation:

• Design AI to augment, not replace, human decision-making
• Ensure meaningful consent for data use
• Build in opt-out mechanisms
• Protect vulnerable populations
• Conduct human rights impact assessments

Examples:

Good Practice: Healthcare AI that assists doctors but preserves doctor-patient relationship and medical judgment.

Poor Practice: AI that makes irreversible decisions about people without human oversight or appeal.

2. Fairness and Non-Discrimination

AI should treat all people fairly and avoid unjust discrimination.

Concepts of Fairness:

Individual Fairness: Similar individuals receive similar treatment.

Group Fairness: Protected groups receive equitable outcomes.

Procedural Fairness: Decision processes are consistent and transparent.

Distributive Fairness: Benefits and burdens are distributed justly.

Challenges:

• Fairness metrics can conflict with each other
• Historical data reflects past discrimination
• Proxies can encode protected attributes
• Context matters - fairness in hiring differs from fairness in lending

Fairness Metrics:

Implementation:

• Test for bias across multiple dimensions (race, gender, age, disability)
• Use diverse, representative training data
• Involve affected communities in design
• Monitor deployed systems for disparate impact
• Be transparent about fairness trade-offs

3. Transparency and Explainability

People should understand how AI systems make decisions, especially when those decisions affect them.

Levels of Transparency:

Process Transparency: How was the AI developed and trained?

• Data sources and collection methods
• Model architecture and algorithms
• Training procedures and validation
• Testing and performance evaluation

Operational Transparency: How does the AI make decisions?

• Input features and their importance
• Decision logic and reasoning
• Confidence levels and uncertainty
• Edge cases and limitations

Outcome Transparency: What did the AI decide and why?

• Explanation of specific decision
• Relevant factors considered
• Alternative outcomes and why they weren't chosen
• Recourse options if decision is disputed

Explainability Techniques:

Model-Agnostic Methods:

• LIME (Local Interpretable Model-agnostic Explanations)
• SHAP (SHapley Additive exPlanations)
• Counterfactual explanations
• Feature importance analysis

Interpretable Models:

• Decision trees
• Linear models
• Rule-based systems
• Generalized additive models

Balancing Act: More complex models (deep learning) often perform better but are harder to explain.

Context-Appropriate Explanation:

• Technical users: Model architecture, parameters
• Domain experts: Feature importance, reasoning
• End users: Plain language, actionable information
• Regulators: Compliance evidence, audit trails

4. Accountability and Responsibility

Clear lines of responsibility when AI causes harm.

Accountability Framework:

Design Accountability: Those who design AI systems must consider potential harms.

Development Accountability: Developers must implement safety measures and test thoroughly.

Deployment Accountability: Organizations deploying AI must use it appropriately and monitor impacts.

Operational Accountability: Humans overseeing AI must exercise judgment and intervene when needed.

Governance Accountability: Leadership must establish AI governance and ensure compliance.

Key Mechanisms:

• Clear roles and responsibilities documented
• Decision audit trails and logging
• Incident reporting and response procedures
• Impact assessments before deployment
• Regular reviews and updates
• Channels for redress and appeals

Accountability Challenges:

• Multiple parties involved (data providers, model developers, deployers)
• Emergent behaviors not anticipated in design
• Autonomous systems making decisions
• Global supply chains and distributed responsibility

5. Privacy and Data Protection

Respecting individuals' privacy and protecting their data.

Privacy Principles:

Purpose Limitation: Collect data only for specified, legitimate purposes.

Data Minimization: Collect only data necessary for the purpose.

Storage Limitation: Retain data only as long as needed.

Accuracy: Ensure data is accurate and up-to-date.

Security: Protect data from unauthorized access or breaches.

Transparency: Inform individuals about data collection and use.

Consent: Obtain meaningful consent for data processing.

AI-Specific Privacy Risks:

• Re-identification from anonymized data
• Inference of sensitive attributes
• Model inversion attacks
• Membership inference
• Data leakage through models

Privacy-Enhancing Technologies:

Differential Privacy: Adding noise to protect individual data points while enabling statistical analysis.

Federated Learning: Training models on distributed data without centralizing it.

Synthetic Data: Creating artificial data that maintains statistical properties without using real individuals' data.

Homomorphic Encryption: Computing on encrypted data without decrypting it.

Secure Multi-Party Computation: Multiple parties jointly compute functions while keeping inputs private.

6. Safety and Security

AI systems must be safe, reliable, and secure.

Safety Considerations:

Physical Safety: AI controlling physical systems (vehicles, robots, medical devices) must not cause physical harm.

Psychological Safety: AI influencing behavior (social media, mental health apps) must not cause psychological harm.

Economic Safety: AI making financial decisions must be reliable and not cause undue economic harm.

Operational Safety: AI in critical systems must fail safely and gracefully.

Safety Measures:

• Comprehensive testing including edge cases
• Fail-safe mechanisms and fallbacks
• Continuous monitoring and alerting
• Human oversight for critical decisions
• Regular safety audits and updates
• Incident response planning

Security Imperatives:

Adversarial Robustness: Resilience against attempts to fool or manipulate the AI.

Data Poisoning Prevention: Protection against malicious training data.

Model Extraction Defense: Preventing theft of AI models through queries.

Access Control: Restricting who can use or modify AI systems.

Integrity Protection: Ensuring AI systems haven't been tampered with.

7. Beneficial and Purposeful AI

AI should serve human wellbeing and the common good.

Questions to Ask:

• What human need does this AI serve?
• Who benefits and who might be harmed?
• Are there better ways to achieve this goal?
• What are the long-term societal impacts?
• Does this AI align with our values?

Beneficial AI Principles:

Human-Centered Design: AI should serve human needs and values, not the reverse.

Inclusive Benefits: AI benefits should be widely shared, not concentrated.

Sustainable Development: AI should support environmental and social sustainability.

Human Autonomy: AI should enhance human capabilities while preserving meaningful choice.

Social Solidarity: AI should strengthen social bonds, not fragment society.

Avoiding Harm:

• Don't build AI for inherently harmful purposes
• Consider dual-use potential (beneficial technology misused)
• Think through unintended consequences
• Monitor for emergent harms
• Be willing to not build or deploy if risks outweigh benefits

8. Transparency About AI Use

People should know when they're interacting with AI.

Disclosure Requirements:

• Inform users when they're communicating with an AI (chatbots, virtual assistants)
• Label AI-generated or manipulated content (deepfakes, synthetic media)
• Disclose AI use in consequential decisions (hiring, lending, law enforcement)
• Explain how to get human review or override

Trust Building: Transparency about AI use builds trust and enables informed consent.

7. Learn and Improve

Reflect and adapt:

• What did we learn?
• What worked or didn't work?
• How can we improve next time?
• What precedents does this set?

Common Ethical Dilemmas

Accuracy vs. Fairness

Dilemma: Optimizing for overall accuracy might lead to worse performance for minority groups.

Example: A medical AI trained mostly on data from one demographic performs less accurately for others.

Considerations:

• What level of disparity is acceptable?
• Should we ensure minimum performance for all groups?
• Can we collect more diverse data?
• Is the use case appropriate for AI given these constraints?

Privacy vs. Utility

Dilemma: More data often improves AI performance but raises privacy concerns.

Example: A health app could provide better recommendations with access to detailed health records, but this creates privacy risks.

Considerations:

• What's the minimum data needed?
• Can we use privacy-enhancing technologies?
• Do benefits justify privacy intrusion?
• Can users meaningfully consent?

Transparency vs. Security

Dilemma: Explaining how AI works might help adversaries attack it.

Example: Explaining fraud detection AI could help fraudsters evade it.

Considerations:

• What level of explanation is needed for trust?
• Can we provide explanations without exposing vulnerabilities?
• Are there alternative ways to build trust?
• Is full transparency worth security risk?

Autonomy vs. Paternalism

Dilemma: Should AI protect people from themselves or respect their choices?

Example: Content recommendation algorithms could shield users from harmful content or respect their stated preferences.

Considerations:

• Who decides what's harmful?
• What are long-term consequences of each approach?
• Can we empower informed choice rather than choosing for users?
• Are there vulnerable populations needing special protection?

Individual vs. Collective Good

Dilemma: What's best for society might not be best for every individual.

Example: Contact tracing AI during a pandemic benefits public health but raises individual privacy concerns.

Considerations:

• How do we balance competing interests?
• Are individual rights being violated?
• Is the collective benefit substantial?
• Are burdens distributed fairly?
• Are there less intrusive alternatives?

Case Studies in AI Ethics

Case Study 1: COMPAS Recidivism Algorithm

System: AI predicting likelihood of re-offending, used in criminal sentencing.

Issue: ProPublica investigation found algorithm was biased against Black defendants.

Details:

• False positive rate (incorrectly predicting recidivism) was higher for Black defendants
• False negative rate (incorrectly predicting no recidivism) was higher for white defendants
• Overall accuracy was similar across groups

Ethical Questions:

• Which fairness metric matters most in criminal justice?
• Should we prioritize equal false positive rates or equal accuracy?
• Is any algorithmic bias acceptable in sentencing?
• Who should decide fairness trade-offs?

Lessons:

• Fairness is multidimensional and contentious
• Historical data reflects societal biases
• High-stakes contexts demand extra scrutiny
• Transparency enables accountability

Case Study 2: Amazon Hiring Algorithm

System: AI screening resumes to identify promising candidates.

Issue: System discriminated against women.

Details:

• Trained on historical hiring data (mostly male candidates in tech)
• Penalized resumes containing "women's" (e.g., "women's chess club")
• Downranked graduates of women's colleges
• Amazon discontinued use

Ethical Questions:

• How do we break cycles of historical discrimination?
• Can AI trained on biased data ever be fair?
• What's the responsibility to audit AI before deployment?
• When should we abandon an AI approach?

Lessons:

• Historical data perpetuates past discrimination
• AI can discover and exploit proxies for protected attributes
• Testing must include fairness metrics, not just accuracy
• Be willing to not use AI if it can't be made fair

Case Study 3: Healthcare AI and Racial Bias

System: Algorithm to identify patients needing extra medical care.

Issue: Systematically underestimated care needs for Black patients.

Details:

• Used healthcare costs as proxy for health needs
• Black patients historically receive less care due to systemic barriers
• Lower costs reflected access disparities, not lower needs
• Result: Black patients had to be sicker than white patients to receive same care level

Ethical Questions:

• What metrics truly measure health needs?
• How do we account for systemic inequities in data?
• Should we adjust for known biases or treat everyone "equally"?
• What's our obligation to address root causes, not just symptoms?

Lessons:

• Proxy variables can encode systemic injustice
• Question whether measurement truly captures what matters
• Context and domain knowledge are essential
• Technical solutions alone can't fix societal problems

Case Study 4: Social Media Algorithmic Amplification

System: AI recommending content to maximize engagement.

Issue: Amplified misinformation, conspiracy theories, and divisive content.

Details:

• Engagement-optimizing AI rewards emotionally charged content
• Radicalization through recommendation rabbit holes
• Filter bubbles limiting exposure to diverse views
• Societal polarization and erosion of shared reality

Ethical Questions:

• What's the responsibility of platforms for content they amplify?
• Should AI prioritize engagement or societal wellbeing?
• How do we balance free speech with harm prevention?
• What are long-term consequences of attention-optimizing AI?

Lessons:

• Optimizing narrow metrics can cause broad harms
• Consider second-order and long-term effects
• Individual and societal wellbeing can diverge
• Business models and incentives shape AI impacts
