Overview

Finding bias in AI systems goes beyond metrics. You need real, diverse perspectives to identify unfair treatment of different user groups.

By reviewing model outputs across demographics, you can catch training data gaps, uncover potential harms, and build AI systems that serve everyone responsibly.

Challenge

Teams face three key barriers when testing for bias: limited access to diverse feedback, delays when scaling across multiple demographics, and inconsistent data quality.

If these challenges aren’t solved, harmful biases will remain undetected, risking reputational damage and reinforcing systemic inequities.

Solution

Prolific removes these barriers with instant access to our 200k+ global community.

Use advanced prescreeners and custom targeting to run demographic‑specific tests at scale. With built‑in quality controls and a flexible API, you’ll get reliable, actionable insights fast—so you can mitigate bias and launch with confidence.
