I’ve been wrestling with a question for years: Why do I always call Jason? Jason is a friend of mine who
always affirms my ideas.
This essay and sketch was my attempt to confront confirmation bias head-on. We’re wired to seek agreement. But that’s how bad decisions happen.
In this episode of Behavior Gap Radio, I share the story behind it, and how I try to push myself to invite dissonance instead of comfort.
This sketch is #92 in the new book. It’s called Stop Calling Jason. You’ll find it in Your Money: Reimagining Wealth in 101 Simple Sketches, coming October 21, 2025.
If you want a preview, I’ve put together a beautifully designed excerpt with seven of my favorite essays and sketches.
📩 Just email hello@behaviorgap.com with the subject line "Friend of Carl" and we’ll send it to you.
You can pre-order the book now. My recommendation? Order one copy from Amazon and one from your favorite local bookstore!
