AI Customer Profiling Discrimination
Companies use AI to profile customers for personalized pricing, credit decisions, insurance rates, and service tiers. The pitch is efficiency — serve each customer optimally based on their data. But AI profiling systematically discriminates through proxy variables. Zip code correlates with race. Browser type correlates with income. Purchase history correlates with health status. The AI doesn't need protected characteristics to discriminate — it finds proxies that achieve the same result while maintaining plausible deniability. Dynamic pricing charges higher prices to customers identified as less price-sensitive (often wealthier, often whiter neighborhoods). Credit algorithms deny loans to qualified borrowers in historically redlined areas. Insurance models charge more to people with certain shopping patterns. The discrimination is invisible because it's statistical, individualized, and hidden behind proprietary algorithms.
What people believe
“AI improves customer targeting and delivers personalized experiences.”
| Metric | Before | After | Delta |
|---|---|---|---|
| Price variation for identical products | Minimal | 10-30% based on profile | +20% |
| Credit approval disparity by zip code | Regulated (explicit) | Unregulated (proxy-based) | Shifted not reduced |
| Targeting efficiency | Demographic segments | Individual-level profiling | +500% |
| Discrimination detectability | Auditable (explicit criteria) | Opaque (algorithmic) | -80% |
Don't If
- •Your AI profiling model uses variables that correlate strongly with protected characteristics
- •You can't explain why different customers receive different prices or service levels
If You Must
- 1.Audit AI models for disparate impact across protected groups regularly
- 2.Remove proxy variables that correlate with race, gender, or other protected characteristics
- 3.Provide transparency into how pricing and service decisions are made
- 4.Implement fairness constraints in model training
Alternatives
- Transparent tiered pricing — Published price tiers based on objective, non-discriminatory criteria
- Fairness-constrained AI — Models trained with explicit fairness constraints that limit disparate impact
- Opt-in personalization — Let customers choose whether to share data for personalized pricing
This analysis is wrong if:
- AI customer profiling produces equitable outcomes across demographic groups without fairness constraints
- Dynamic pricing based on AI profiling benefits consumers overall compared to uniform pricing
- Proxy discrimination in AI models is detectable and correctable through standard auditing practices
