The Science of Choice: Uncovering the Roots of Unconscious Bias in Infants

In a recent episode of Wow in the World, Mindy and Guy Raz explore the fascinating origins of human decision-making and the development of unconscious bias. Through a chaotic, humorous experiment conducted in their "laboratory of bad ideas," the hosts recreate a study from the journal Psychological Science to determine when humans begin to favor certain choices over others—even when those choices are fundamentally identical.

Understanding Unconscious Bias

Guy Raz defines unconscious bias as "the thoughts and feelings we have for certain things that influence how we make decisions, even when we're not aware of it." Mindy provides a lighthearted example of this using frosting colors on a gingerbread mansion, noting that we often choose one option over another without a logical reason. The episode posits that adults spend their lives making decisions based on these hidden biases, such as preferring specific brands of toothpaste or snacks—like Mindy’s peculiar preference for "exploding ants" over "exploding aunts."

The Johns Hopkins Experiment

To investigate when this behavior begins, the hosts reference cognitive science researchers at Johns Hopkins University who studied infants. The core question was: at what point do humans start to develop a preference for an object simply because they chose it?

In the experiment, researchers presented babies with two equally appealing toy blocks. Once a baby selected one, the researchers removed the chosen toy and offered a new, different toy alongside the one the baby had previously ignored. The researchers observed that most babies preferred the brand-new toy over the one they had rejected in the first round.

The "Choice" Factor

As Dr. Fegenson, one of the lead researchers, noted, it appeared as though the babies were internally reasoning, "I didn't choose that object the first time, I guess I just didn't like it very much."

The study revealed a critical insight: unconscious bias requires the element of choice. When researchers conducted follow-up experiments where they assigned toys to the babies (removing the ability for the child to choose), the infants displayed no strong preference between the toys.

Conclusion

This experiment suggests that our tendency to like what we choose—and dislike what we reject—is not a learned behavior developed in adulthood, but rather one that begins at the earliest stages of life. By making our first random choices as infants, we set the foundation for the biases that influence our adult lives. The episode concludes by highlighting that being aware of these biases is the first step toward checking ourselves, ensuring that our unconscious preferences don't unfairly color how we perceive the world and the people around us.
