The Latticework of Mental Models For A Great Life – Mohnish Pabrai (Transcript) 

Editor’s Note: In this insightful SXSW talk, renowned investor Mohnish Pabrai shares a curated sampler of mental models geared toward successfully starting and running a business. Drawing inspiration from legendary thinkers like Charlie Munger and David Hawkins, he explains how compounding simple truths can lead to an exponential advantage in both career and everyday life. Ultimately, Pabrai shifts the traditional entrepreneurial focus away from making money, urging the audience instead to focus on the relentless pursuit of high-quality service to humanity.

Introduction and Overview

MOHNISH PABRAI: Thank you. Thank you, Michelle. Great to be here, and thank you for taking the time to come to this session.

Charlie Munger and the Psychology of Human Misjudgment

Charlie Munger had given a talk a few decades back at Harvard, The Psychology of Human Misjudgment, and then later he revised that talk for Poor Charlie’s Almanac, which is wonderful. I try to reread it every year, but it took me many, many years to understand what Charlie was talking about. Even though he tried to dumb it down for all of us, it still took me a while, and so I wanted to kind of present some of these things related to mental models in a little bit different context and different format than he does.

What Are Mental Models?

Mental models are realities that when we encounter them for the first time, surprise us. We already understand a lot of things about how the world works, but we’ll encounter things periodically which are like, huh, I didn’t think that was true, but when we encounter these truths and we incorporate them into how we make decisions, we’ll start getting advantages versus other humans who may actually work harder and maybe even be smarter and so on.

It’s really when you start cascading the models together in the same direction for the same effort, that’s when you get what Munger would call Lollapalooza effects, you know, one plus one becomes eleven and one plus one plus one plus one becomes over a thousand and so on.

The Bedrock Model: Take a Simple Idea and Take It Seriously

So the bedrock model, and without this model, the other models don’t work. So this is like, if you didn’t buy into this model, then there’s no point looking at anything else, and that is that you take a simple idea and you take it seriously.

So when you encounter these things that kind of sound strange or sound weird, but you are convinced eventually that it is reality with the way the world works, you have to go all in. And if you don’t go all in, then it just kind of just doesn’t work. So no matter what we are doing, anytime we’re using this latticework of mental models together, we always have to have model one, which is the take it very seriously.

Power Versus Force: Truth on a Log Scale

There’s a kind of a new age guru in Sedona, Arizona, who’s passed away now, David Hawkins, and he wrote this book called Power Versus Force. And when I recommend this book to people I know, I get kind of one of two reactions. They’re either ready to throw the book at me, hoping it hurts me, or they love it. I never get a reaction saying, ah, it was okay. I’ll never get kind of a middle reaction. I’ll get just extreme reactions, one end or the other end.

And so David Hawkins has this perspective on, so we think of the truth as being binary, you know, kind of one or zero. You’re either lying or saying the truth, but that’s not really how the truth and lies work. It’s actually on a log scale.

So if we look at this graph and you go in the top right-hand end of the graph, that’s where you might have Jesus and Buddha hanging out, you know, extreme truth leading to extreme trust, right? So we just kind of, and you know, us humans aren’t going to get there, but that’s at the extreme end. That’s kind of aspirational. Then you go a little bit below that and you get to people like Warren Buffett, and again, or Charlie Munger, you know, which is as high as you can get as a capitalist. And then if you go significantly below that, you get to many of us.

And it’s very important in life to try to move as far to the right of that curve as you can, because as you move further right on that curve, the payoffs are exponential. So I’ll give you an example of kind of why this is not binary, because all of us think, well, you know, I always say the truth, you know, I’m not a deceitful person and all of that.

Truth, Trust, and the Cost of Small Lies

But let’s say my partner and I are going to go out on date night and she’s ready and she asks me, how do I look? Right? And now let’s say I think the dress isn’t that great, you know, and I know that if I say that the dress isn’t great, you should change your dress, right? That might be the end of the date night.

So the pre-David Hawkins Mohnish would have said, oh, you look great, let’s go. Right? And the post-David Hawkins Mohnish will not want to deal with the white lies. And I’ll just say that I don’t think the dress is great. I think you should change the dress. Right. And it may lead to no date that night, which is fine. But what’s going to happen over time is the trust is going to go up big time.

So what you have to do as you go through life is get rid of the small lies. And the small lies are happening all the time, because life is more convenient with the small white lies here and there.
