Module 10 Lesson 2: Reducing Bias and Hallucinations
How to identify and mitigate AI bias and 'hallucinations' for more objective and reliable results.
Reducing Bias and Hallucinations
AI bias isn't just a "social" issue; it's a quality issue. If your market research only reflects one demographic, your data is flawed.
1. What is AI Bias?
AI models are trained on the internet, which is a reflection of human history—including our prejudices.
- Example: If you ask for a "picture of a CEO," older models might only show men in suits.
2. Reducing Hallucinations (The "Anchor" Technique)
A "Hallucination" happens when the model's logic breaks free from its facts.
- The Fix: Provide the Facts.
- Instead of: "Write about the solar system."
- Use: "Based on the attached NASA fact sheet, describe the surface of Mars."

3. Diversifying Personas
- "Analyze this marketing campaign from three perspectives: A Gen Z consumer in New York, a retired farmer in Iowa, and a technology consultant in Tokyo."
4. The "Devil's Advocate" Prompt
Force the AI to see the other side.
- "I have written this argument in favor of [Topic]. Now, act as a harsh critic and find 3 ways my argument might be biased or based on incomplete data."
Hands-on: Comparison Test
- Prompt: "Who is the most influential person in the world?"
- Prompt: "Who is the most influential person in the world? Provide the answer from a Western perspective, a Chinese perspective, and an Indian perspective."
Observe how the second prompt reveals the subjectivity inherent in the question.
Key Takeaways
- Bias is everywhere. Always look for it.
- Anchor your prompts in data to stop hallucinations.
- Use Multi-perspective prompts for objectivity.
