Welcome to the show. I'm Jordan Harbinger.

On the Jordan Harbinger Show, we decode the stories, secrets and skills of the world's most fascinating people

and turn their wisdom into practical advice that you can use to impact your own life and those around you.

Our mission here on the show is to help you become a better informed, more critical thinker

through long-form conversations with a variety of incredible people from spies to CEOs, athletes, authors, thinkers to performers,

even the occasional former cult member rocket scientist.

If you're new to the show or you want to say your friends about the show, our episode starter packs are a great place to do it.

These are collections of our favorite episodes on persuasion, negotiation, disinformation, crime, cults and more.

And I hope new listeners get a taste of everything we do here on the show.
