Early this year, I read the updated version of Poor Charlie’s Almanack, a collection of Charlie Munger’s speeches on mental models and psychology. The book was a masterclass on decision-making. Since then, I’ve reread sections of the book and found recordings of the speeches. What Charlie Munger shares in those speeches is knowledge and insight that he spent decades acquiring. His wisdom feels like a cheat code, and I want to leverage it fully.

I wanted a cheat sheet of Munger’s wisdom to reference as I make decisions. During my research, I found something pretty helpful. It’s an animated video that condenses the most important lessons from Munger’s 1995 speech “The Psychology of Human Misjudgment,” which lasted about 75 minutes, into 14 minutes.

Tiny, a publicly traded Canadian holding company that acquires and owns businesses long-term, created the video. Here’s what its cofounder, Andrew Wilkinson, said this week in his newsletter about why they created the video:

In 1995, Charlie Munger, Warren Buffett’s longtime business partner, gave an incredible speech about why humans do stupid things.

In it, he breaks down all the key psychological effects that warp our thinking and cause bizarre behavior.

In 2014, I made it my mission to memorize this talk. I listened to it every single day on my drive to work and tattoo’d it into my brain.

It has been one of the most durable and important pieces of content I’ve ever consumed, and a few years ago, Chris and I decided to make it more accessible.

We took the original hour long scratchy audio recording and turned it into a shorter and more accessible animated video.

I’ll still create a cheat sheet, but I’m going to test Wilkinson’s approach and listen to this video daily to see if doing so accelerates my understanding of the concepts Munger discussed in this speech.
