Bias in AI

Bias in AI is like having a salesperson who unconsciously favors certain customers over others—except the AI does it at scale, consistently, and often invisibly. The problem stems from three sources: biased training data (the AI learned from historical examples that contained prejudice), biased design choices (engineers built assumptions into the system), or biased feedback loops (the system reinforces its own mistakes over time).

Think of it this way: if you train an AI to predict which customers are most likely to buy premium products, but your historical data shows that your sales team spent more time with male customers, the AI will learn to prioritize men—not because it's programmed to, but because that's what the data taught it. The AI isn't being deliberately discriminatory; it's being statistically accurate about your past behavior, which was biased.

In marketing tools, bias shows up concretely. An AI-powered ad targeting system might learn to show luxury product ads primarily to certain zip codes or demographics, not because you told it to, but because those groups clicked more in the training data. A predictive lead-scoring model might systematically undervalue leads from underrepresented groups. An email subject line generator might produce language that resonates better with one gender than another.

For CMOs, this matters because biased AI systems create three risks: legal exposure (discrimination lawsuits), brand damage (when bias becomes public), and missed revenue (you're excluding customers who would buy). When evaluating AI vendors, you need to ask: What data was this trained on? How do they test for bias? Do they monitor for it in production? The best vendors provide bias audits and allow you to see how their system performs across different demographic groups.
