45 Project Lifecycle
45.1 Introduction
Now that we have laid the groundwork for a general understanding of applied ethics in data science, we connect the concepts back to the phases of the data science project lifecycle. For each phase of the lifecycle, we ask
- What are key questions that should be asked?
- What are red flags that should halt a project?
- What are the stakeholder considerations?
- What bias detection strategies are available?
The case studies that follow illustrate both the potential for significant harm when ethics are neglected and the possibility of responsible deployment when ethical principles guide decision-making. These examples prove that ethical considerations must be integrated throughout the entire data science lifecycle, not treated as an afterthought.

45.2 Business Understanding: Discovery
Understanding the business context and defining the problem is where ethical considerations begin. Poor decisions at this stage can lead to harmful outcomes regardless of technical execution quality.
Key Ethical Questions
- Purpose & Impact: What problem are we solving and for whom? Could this solution cause harm to individuals or groups?
- Stakeholder Analysis: Who benefits from this project? Who might be negatively impacted? Are affected communities represented in decision-making?
- Necessity & Proportionality: Is a data science solution necessary, or could simpler approaches work? Are we using the minimum data required?
- Legal & Regulatory: What laws, regulations, and industry standards apply? Do we have proper legal basis for data processing?
- Success Metrics: How do we define success? Do our metrics align with ethical outcomes and societal benefit?
Red Flags
- Discriminatory Intent: The project explicitly aims to discriminate against protected groups
- Illegal Activity: The project violates regulations (GDPR, CCPA, anti-discrimination laws, etc.)
- Vulnerable Populations: The project targets vulnerable groups without proper safeguards and oversight
- Lack of Consent: No clear legal basis exists for data collection or processing
- Disproportionate Harm: Potential negative impacts significantly outweigh benefits
- Mission Creep: Project scope expands beyond original ethical boundaries without review
Stakeholder Considerations
Bias Detection Strategies
- Problem Framing Bias: Are we defining the problem through a particular cultural or organizational lens?
- Stakeholder Representation: Are decision-makers demographically diverse and representative?
- Historical Context: Does the business problem perpetuate historical inequities?
- Assumptions Audit: What assumptions are we making about user behavior, preferences, or capabilities?
- Alternative Approaches: Have we considered non-algorithmic solutions that might be less biased?
Example: Amazon’s Biased Hiring Algorithm (2018)
Amazon developed an AI recruiting tool to streamline hiring by scoring resumes from 1 to 5 stars. The goal was to feed the AI tool hundreds of resumes and it would return the top 5 or 10 best candidates. It had a number of ethical issues:
- Problem Framing: The system was trained on historical hiring data from a male-dominated industry
- Success Metrics: Optimized for past hiring patterns rather than diverse, qualified candidates
- Stakeholder Representation: Lacked input from diversity and inclusion experts
The system systematically downgraded resumes containing words like “women’s” (as in “women’s chess club captain”) and showed bias against graduates from all-women’s colleges. Amazon scrapped the project.
Lessons
- Historical data reflects historical biases
- Technical optimization without ethical constraints can perpetuate discrimination
- Early stakeholder engagement is crucial
Example: COVID-19 Contact Tracing Apps
During the COVID-19 pandemic, governments worldwide developed contact tracing apps to slow the spread of the pandemic.
Ethical Considerations
- Necessity vs. Privacy: Balancing public health benefits against privacy invasion
- Vulnerable Populations: Ensuring the technology doesn’t exclude those without smartphones
- Mission Creep: Preventing surveillance expansion beyond stated public health purposes
- Consent: Voluntary vs. mandatory adoption debates
Different Approaches
- Singapore’s TraceTogether: Initially voluntary, later made mandatory for certain venues
- Germany’s Corona-Warn-App: Fully voluntary, decentralized approach
- Apple/Google Exposure Notification: Privacy-preserving framework with limited data collection
Lessons
- Same technology can be implemented with vastly different ethical implications
- Transparent governance and clear limitations are essential
- Public trust depends on keeping promises about data use
45.3 Data Engineering
This phase covers both understanding available data and preparing it for analysis. Ethical issues in data engineering can fundamentally compromise the entire project.
Key Ethical Questions
- Data Provenance: Where did this data come from? Was it collected ethically and with proper consent?
- Representativeness: Does this data fairly represent the population it claims to represent?
- Privacy & Sensitivity: What sensitive information is contained in the data? How is it protected?
- Data Quality: Are there systematic biases, errors, or gaps in the data?
- Temporal Relevance: Is historical data still relevant, or might it reflect outdated social conditions?
- Data Minimization: Are we using only the data necessary for the stated purpose?
- Anonymization: Can we anonymize or pseudonymize data while maintaining utility?
- Bias Amplification: Will our data preprocessing steps amplify existing biases?
- Transparency: Can we explain our data preparation decisions to stakeholders?
- Reversibility: Can we undo our transformations if needed?
Red Flags
- Illegally Obtained Data: Data were collected without proper authorization or consent
- Highly Sensitive Content: Data contain highly sensitive information without proper safeguards
- Known Biased Sources: Data come from sources with documented bias or discrimination
- Incomplete Consent: Individuals did not consent to this specific use of their data
- Data Trafficking: Data were obtained through questionable third-party brokers
- Inadequate Documentation: Cannot trace data lineage or verify ethical collection practices
- Impossible Anonymization: Cannot adequately protect individual privacy
- Bias Amplification: Preprocessing steps systematically disadvantage certain groups
- Excessive Data Retention: Keeping more data than necessary or for longer than needed
Stakeholder Considerations
Bias Detection Strategies
- Demographic Analysis: What groups are over/under-represented in the data?
- Temporal Bias: Does data reflect different time periods that might introduce bias?
- Selection Bias: How were the data selected, and what systematic biases might this introduce?
- Measurement Bias: Are there systematic errors in how data were collected or measured?
- Proxy Discrimination: Do the data contain proxies for protected characteristics?
- Missing Data Patterns: Are there systematic patterns in missing data that correlate with demographics?
- Feature Selection Bias: Are we selecting features that may discriminate against certain groups?
- Sampling Bias: Do our sampling strategies fairly represent all populations?
- Normalization Bias: Do standardization approaches work equally well across groups?
- Imputation Bias: Are missing value strategies fair across different demographics?
- Outlier Treatment: Are we systematically removing data points from certain groups?
- Synthetic Data Bias: If generating synthetic data, does it preserve fairness characteristics?
Example: Google Photos Racial Classification Error (2015)
Google Photos’ automatic tagging system labeled photos of Black people as “gorillas.”
Data Engineering Issues
- Training Data Bias: Insufficient representation of diverse skin tones in training data
- Feature Engineering: Image processing algorithms optimized for lighter skin tones
- Quality Assurance: Inadequate testing across demographic groups
Technical Response: Google initially blocked the terms “gorilla,” “chimp,” and “monkey” from its image labeling system entirely.
Long-term Impact: As of 2023, Google Photos still doesn’t label primates, highlighting the lasting impact of biased data engineering decisions.
Lessons
- Diverse training data is essential but not sufficient
- Testing must be comprehensive across all represented groups
- Quick fixes may not address underlying algorithmic bias
Example: Facebook’s “Real Name” Policy
Facebook required users to provide their legal names, ostensibly to create a safer, more accountable platform.
Data Collection Issues
- Cultural Bias: Policy assumed Western naming conventions were universal
- Vulnerable Populations: Disproportionately affected LGBTQ+ individuals, domestic violence survivors, and indigenous communities
- Identity Verification: Lacked understanding of diverse identity documentation practices
Impact
- Drag performers were locked out of accounts
- Native Americans with traditional names faced verification challenges
- Transgender individuals were forced to use deadnames
Resolution: Facebook eventually modified the policy to allow “authentic names” rather than legal names, but only after significant advocacy.
Lessons
- Data collection policies must consider diverse global contexts
- “Universal” standards often reflect dominant cultural perspectives
- Community input is essential for inclusive data practices
Example: COVID-19 Vaccine Distribution Algorithms
Healthcare systems used algorithms to prioritize vaccine distribution during shortages.
Data Engineering Considerations
- Health Equity: Ensuring algorithms account for health disparities
- Data Access: Populations with limited healthcare access had less representation in health databases
- Geographic Bias: Urban vs. rural data availability differences
- Socioeconomic Proxies: Using insurance type or healthcare utilization as risk factors
Different Approaches
- Individual Risk: Focus on personal health factors (age, comorbidities)
- Community Risk: Prioritize high-transmission areas or essential workers
- Equity-Based: Explicitly account for historical health disparities
Challenges
- Data Quality: Incomplete health records for vulnerable populations
- Feature Selection: Choosing which health and demographic factors to include
- Geographic Granularity: Neighborhood-level vs. individual-level prioritization
Lessons
- Data engineering decisions directly impact life-and-death outcomes
- Equity considerations may require deliberately collecting additional data
- Community input is essential for legitimate and effective algorithms
45.4 Modeling Data
The modeling phase transforms prepared data into predictive or descriptive models. This is where algorithmic bias most directly manifests and where fairness interventions are often applied.
Key Ethical Questions
- Algorithmic Fairness: What definition of fairness are we using, and is it appropriate?
- Interpretability: Do we need to understand how the model makes decisions?
- Performance Disparities: Does the model perform equally well across different groups?
- Unintended Consequences: What could go wrong if the model is deployed?
- Human Oversight: What role will humans play in model decisions?
Red Flags
- Significant Performance Disparities: Model systematically performs worse for certain groups
- Impossible to Explain: Cannot provide meaningful explanations for high-stakes decisions
- Reinforces Discrimination: Model perpetuates or amplifies historical biases
- Unstable Performance: Model behavior is unpredictable or inconsistent
- No Human Oversight: Critical decisions made without human review capability
- Adversarial Vulnerabilities: Model easily manipulated or gamed
Stakeholder Considerations
Bias Detection Strategies
- Demographic Parity: Does the model make similar decisions across demographic groups?
- Equalized Odds: Are false positive and false negative rates similar across groups?
- Calibration: Are confidence scores equally meaningful across groups?
- Individual Fairness: Are similar individuals treated similarly by the model?
- Counterfactual Fairness: Would decisions change if sensitive attributes were different?
- Intersectional Analysis: How does the model perform for individuals with multiple protected characteristics?
Example: Healthcare AI Bias in Pulse Oximetry
Pulse oximeters are widely used medical devices; they have been found to overestimate blood oxygen levels in patients with darker skin tones.
Modeling Issues
- Training Data: Historical calibration data primarily from patients with lighter skin
- Feature Engineering: Algorithms optimized for light transmission through lighter skin
- Validation: Insufficient testing across diverse populations
COVID-19 Impact: During the pandemic, this bias led to delayed treatment for Black, Hispanic, and Asian patients who appeared to have adequate oxygen levels according to pulse oximetry but actually had dangerously low levels.
Systemic Consequences
- Estimated that bias led to delayed treatment for thousands of patients
- Highlighted broader issues with medical device testing and approval processes
- Sparked FDA guidance on addressing bias in medical AI
Modeling Lessons
- Model performance must be evaluated across all relevant subgroups
- Domain expertise is crucial for identifying potential bias sources
- Regulatory frameworks must evolve to address algorithmic bias
Example: Bias Amplification through Language Model
Large language models like GPT, BERT, and others have been found to amplify social biases present in training data.
Documented Biases
- Occupational Stereotypes: Associating certain professions with specific genders
- Racial Stereotypes: Negative sentiment associated with certain names or descriptions
- Religious Bias: Stereotypical associations with different faith communities
- Cultural Bias: Western-centric perspectives and assumptions
Research Examples
- Word Embeddings: “Computer programmer” closer to “man” than “woman” in vector space
- Sentence Completion: Biased completions for prompts about different groups
- Translation: Gender-neutral languages translated with gender stereotypes
Mitigation Approaches
- Debiasing Techniques: Post-processing to reduce biased associations
- Adversarial Training: Training models to be invariant to protected attributes
- Diverse Training Data: Curating more representative datasets
- Human Feedback: Using human evaluation to identify and correct biases
Ongoing Challenges: - Bias-Accuracy Tradeoffs: Debiasing may reduce overall model performance - Multiple Bias Types: Difficult to address all forms of bias simultaneously - Cultural Context: Bias definitions vary across cultures and contexts - Dynamic Nature: Biases evolve as language and society change
Lessons
- Large models can amplify subtle biases at scale
- Technical solutions must be combined with diverse human oversight
- Bias mitigation is an ongoing process, not a one-time fix
Example: Algorithmic Trading and Market Manipulation
High-frequency trading algorithms can inadvertently create market instability or be exploited for manipulation.
Flash Crash of 2010
- Trigger: Large sell order executed by algorithm
- Amplification: Other algorithms responded automatically, creating feedback loop
- Impact: Market dropped 9% in minutes, recovering almost as quickly
Modeling Considerations
- Feedback Loops: How algorithms interact with other market participants
- Systemic Risk: Individual model decisions affecting entire market
- Fairness: Whether algorithmic trading creates unfair advantages
- Transparency: Balancing competitive secrecy with market stability
Regulatory Response
- Circuit Breakers: Automatic trading halts during extreme volatility
- Position Limits: Restrictions on algorithm trading volumes
- Monitoring: Enhanced surveillance of algorithmic trading patterns
Ethical Questions
- Market Fairness: Do high-speed algorithms create unfair advantages?
- Systemic Risk: Who bears responsibility for algorithm-induced market instability?
- Social Benefit: Do algorithmic trading benefits justify potential harms?
Lessons
- Individual model decisions can have systemic consequences
- Complex systems require ongoing monitoring and intervention capabilities
- Technical optimization without considering system-wide effects can be harmful
45.5 Communication and Reporting
