Bias

What is authority bias?

The authority bias describes our tendency to be more influenced by the opinions and judgments of authority figures. This bias can lead people to accept information or follow instructions without critically evaluating the content, simply because it comes from a perceived authority. 

The image shows three stick figures. The figure on the right is seated and wearing a colorful, elaborate hat. The figure in the middle is holding a sign that reads, "He knows everything because he has a funny hat!" The figure on the left is standing and facing the other two. The background is a simple red ground with a gray sky, and the text "Authority Bias" is written at the top of the image.

Where this bias occurs

Dr. Elizabeth Turner, world-leading geneticist and director at a large Biotech company, is embarking on a ground-breaking research project. She is analyzing the potential applications of a novel gene-editing technology, an area she has specialized in for over two decades.

In a company-wide meeting, Dr. Turner passionately presents her findings, emphasizing the transformative impact the technology could have on medical treatments. Her colleagues, attuned to her reputation for innovative research, absorb her words with admiration. Dr. Turner’s authority within the organization cast a favorable light on her proposed advancements.

A few weeks later, a junior researcher, Lisa, cautiously introduces a counterpoint to Dr. Turner’s methodology, proposing an alternative approach to achieve better outcomes. Despite Lisa’s well-reasoned argument and robust evidence, there’s a subtle resistance to her suggestion among the team. Dr. Turner’s long-standing reputation and position as director eclipses the merits of Lisa’s alternative proposal.

In this scenario, the authority bias influenced how the two proposals were received and evaluated by the rest of the team. In other words, when it came to evaluating the individual merits of the two scientists’ research, their level of authority and seniority within the company had more weight than the actual content of their proposals. In fact, Lisa’s alternative approach may have been seriously considered if Dr. Turner or another senior scientist at the company had presented it on her behalf.

I was blown away with their application and translation of behavioral science into practice. They took a very complex ecosystem and created a series of interventions using an innovative mix of the latest research and creative client co-creation. I was so impressed at the final product they created, which was hugely comprehensive despite the large scope of the client being of the world's most far-reaching and best known consumer brands. I'm excited to see what we can create together in the future.
