Unconscious and Implicit Bias

Published on 01/08/2025

What is unconscious bias?

Research reveals that even those with strong egalitarian values who consider themselves unbiased may unconsciously behave in discriminatory ways. Studies on unconscious and implicit bias demonstrate that our intuition and snap judgments are often less rational than we believe.

UCLA provides a video series that usefully summarizes these concepts.

Why does it matter?

By acknowledging these hidden biases and designing systems that minimize their influence, we can improve fairness and help level the playing field in many areas of society, such as business and education. For instance, when we reduce how unconscious biases affect hiring decisions, we ensure more rational selection criteria—benefiting both businesses and society through more competitive hiring practices.

What can we do about it?
