Denial

What if the same trait that makes us human… is also what could destroy us?

In Denial, authors Ajit Varki and Danny Brower explore a mind-bending theory: that the ability to deny reality is not a flaw—but a key feature of human evolution. It’s uncomfortable. It’s controversial. And it’s incredibly important.

“Without the capacity for denial, humans might never have developed self-awareness—or survived long enough to use it.”

Wait—what?

This book turns everything you think you know about human psychology on its head. Varki and Brower propose that denial is not just a psychological defense mechanism. It’s a survival tool hardwired into our species. One that allowed us to become self-aware without collapsing under the existential dread of knowing we’re going to die.

Sounds wild, right? But they back it up. With evolutionary biology. Neuroscience. Case studies. And chilling real-world consequences—from climate change denial to political polarization.

The best part? It’s not just theory. This book gives you practical, mind-expanding insight into why people ignore facts, how denial plays out in everyday life, and what we can actually do to break through it.
