Is AI solution biased? Well before asking this question, let us dwell more into human nature, is human response or process building biased, it has to be, it forms the basis of selecting criteria, a baseline on which the entire process is set or supposed to operate. Similarly, when we create an AI agent there will be a bias in AI-enabled customer service processes, especially in banking—can have serious consequences, from unfair treatment of customers to regulatory violations.
Let’s break this down using your example of a third-party contact center handling banking queries, such as Annual Maintenance Charges (AMC) or unauthorized UPI transactions, and explore how bias can creep in and how to mitigate it.
What Bias Can Appear in Banking Customer Service and Where?
1. Case Prioritization
Risk of bias: AI may prioritize cases based on customer profile (e.g., high-value customers), potentially delaying resolution for others.
E.g: AMC-related queries from senior citizens may be deprioritized if the model learns they are less likely to escalate.
2. Action Recommendations
Bias possibility: AI may suggest refunds or escalations based on historical patterns that reflect biased decisions.
Example: UPI fraud cases from Tier-2 cities may be less likely to get recommended for escalation due to historical underreporting.
3. Response Generation
Bias Risk: Regional models may respond taking into consideration the tone of voice, choice of words, AI agent will respond differently given the tone, politeness and choice of words for customers based in northern part of India versus the same AI agent might find the customer’s similar language or choice of words as rude or condescending and might deny service in southern part of India. Language models may respond differently based on customer name, language, or tone.
Example: A polite query may get a more helpful response than an agitated one, even if both are valid.
4. Billing Model Influence
Bias Risk: If billing is based on connect minutes, agents may be incentivized to prolong calls. If based on call count, they may rush.
Example: AMC queries may be wrapped up quickly without full resolution under a per-call billing model.
So, what do we do to minimize bias in Design, Testing, and Monitoring
A. Design Phase
Diversify Training Data
Be it low income customers or high rollers, you might want to include varied customer profiles, geographical regions of customers, languages, net worth of customers, and complaint types.
Low amount frauds or frauds based on a certain amount should not matter when a customer is complaining of an unauthorized transaction by a merchant. There is a possibility of bias setting in based on a low or high amount transaction, AI might prioritize only high amount unauthorized transaction cases.
We must ensure representation of certain vulnerable groups (e.g.,low income, senior citizens, rural customers).
Provide clear objectives that kill bias
Design AI models with fairness constraints (e.g., equal resolution rates across demographics).
Avoid optimizing solely for efficiency metrics like AHT (Average Handling Time).
Human-in-the-Loop
Keep humans involved in sensitive decisions (e.g., refund approvals, fraud escalations).
B. Testing Phase
Inclusion of Bias Audits
Test model outputs across different customer segments.
Use synthetic data to simulate edge cases (e.g., same query from different regions).
Scenario-Based Testing
Create test cases for AMC and UPI queries with varying tones, languages, and urgency levels.
Check for consistency in response quality and resolution.
Metric Diversification
Track fairness metrics alongside performance metrics (e.g., resolution equity, escalation parity).
C. Monitoring Phase
Set up real-time dashboards
Monitor call outcomes by customer segment, query type, and agent behavior.
Flag anomalies (e.g., unusually short calls for UPI fraud cases).
VOC : Feedback
Collect customer feedback post-call and correlate with AI decisions.
Use feedback to retrain models and adjust flows.
Billing Model Alignment
Ensure billing models don’t incentivize biased behavior.
Consider hybrid models (e.g., quality-adjusted call count) to balance efficiency and fairness.
How do we break the “Bias In, Bias Out” Cycle
Continuous Learning: Regularly update models with new, unbiased data and feedback.
Make it transparent: Make AI decision-making explainable to agents and supervisors.
Assign ownership: as a check mechanism, assign accountability for bias monitoring and remediation.
Cross-Functional Collaboration: Involve friendly customer base, compliance team, QA team, and customer experience teams in AI governance.
