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.
