Why do we instinctively add when the better answer might be less?

In this episode of the Truth Works Podcast, we sit down with Leidy Klotz—behavioral scientist, engineer, and author of Subtract—to explore why subtraction is one of the most underused tools in problem-solving, design, and even life itself. From ancient architecture to modern innovation, Leidy unpacks the hidden bias that keeps us adding complexity instead of removing it.

We dive into how this instinct shapes everything from personal decisions to global policy, and how changing it could transform the way we think, create, and lead.
