Hey Friends,

Few things will change your trajectory in life or business as much as learning to make effective decisions. Yet no one really teaches us what it means to make consistently high-quality decisions.The decision-making principles in this article are both practical and time-tested. They work in the real world.

No one Taught you How to Decide

Just out of college, I found that my decisions affected not only my family but all other people around me. Back then, I had no idea how to make smart decisions. I had no idea how to reduce errors. I only knew I had an obligation to make the best decisions I could. But where do you start?

There is no class called “decision making.” Making better decisions isn’t one skill but rather a series of tools and frameworks. What distinguishes consistently good decision-makers from poor ones is a series of diverse mental frameworks and tools (as well as relevant specific information).

Most of us operate like a carpenter with only a hammer. To a man with a hammer, every problem looks like a nail. No matter the job, we pull out our hammer and attempt to make it work. While a hammer can often get the job done eventually, it comes with a cost.

“The older I get the more I realize how many kinds of smart there are. There are a lot of kinds of smart. There are a lot of kinds of stupid, too.”

— JeFF Bezos

To fill my mental toolbox, I looked around my organization and found some mentors. I watched them, asked them annoying questions, and tried to learn as much as I could from them. I read everything I could about making decisions and the tools I needed to develop. Thanks to the internet, I was no longer limited to the best teachers in my organization or university. The entire world was available. I could find the best teachers in the world, learn their tools and frameworks, and add them to my mental toolbox.

Your Mind is a Pattern Matching Machine

You probably don’t know it but you already think in mental models. Mental models are mental chunks of knowledge that represent a concept. Gravity is a model. So are probabilistic thinking, inversion, and entropy.

Mental models shape how you think, how you approach problems, and how you identify the information that matters and ignore what doesn’t. The mental models in your head are your cognitive skillset.

Decision Making

Think about the state of your life, your career, your business, your major relationships — anything consequential to you. How many important decisions have you already had to make? With the benefit of hindsight, how well did you make them? How many decisions did you make today? How did you make these decisions? Is there a better way?

Not all decisions matter. Most decisions, like where to have lunch, are unimportant. The consequences of these decisions don’t matter. Yet some decisions are critical — they change our lives. Whether it’s who to trust, where to work & live, or whom to marry, these decisions reverberate for years.

Yet most of us don’t have the right skills to think through these problems. As a result, we often fall back to the pro-con list, where you list all the positive things that happen on one side and the negative things on the other trading them off.

While useful when deciding what to have for lunch, the pro-con list comes with a lot of blind spots.

“I regard it as a criminal waste of time to go through the slow and painful ordeal of ascertaining things for one’s self if these same things have already been ascertained and made available by others.”

— Thomas Edison

SMART People Make Terrible Decisions

Think about decisions like these:

• Napoleon decided to invade Russia (and Hitler did it again 130 years later)
• NASA’s decision to ignore the O-ring issues on the Challenger
• President Kennedy’s famous blunder to continue the Bay of Pigs operation inherited from the previous administration (a mistake he quickly learned from)
• Margaret Thatcher deciding to get behind a “poll tax” that led to her ouster by her own party
• Juergen Schrempp, the CEO of Daimler-Benz, deciding to merge with Chrysler despite massive internal opposition and general history of big M&A deals working very poorly.
• ……………and a hundred thousand more………..

These were catastrophic decisions made by people who were, in some sense, professional decision-makers. They had impeccable credentials and judgment, and yet they made poor decisions due to poor judgment, too-limited mental representations of the world, or just plain stupidity.

Sources of Stupidity

There are a lot of reasons we fail to make effective decisions. Let’s take a look at five of the biggest ones:

1. We’re unintentionally stupid. I like to think that I’m rational and capable of interpreting all information in a non-biased way but that’s a dream. Cognitive biases are great at explaining how our evolutionary programming leads us astray. Knowledge of these biases in advance rarely helps us make better decisions. There are, however, many easily recognizable situations that increase the odds we’re about to do something stupid. Whether we’re tired, overly focused on a goal, rushing, distracted, operating in a group, or under the influence of a group, we’re more prone to stupidity.

2. We have the wrong information. Making decisions with the wrong assumptions or facts is likely to lead to disaster.

3. We use the wrong model. We use mental models to make decisions. The quality of those models determines the quality of our thinking. There are a variety of reasons that we use false, incomplete, or incorrect models. Novices are prone to using models that the expert knows are incomplete or irrelevant. The odds of employing the wrong models increase as the pace of environmental change increases.

4. We fail to learn. We all know the person that has 20 years of experience but it’s really the same year over and over. Well, that person is sometimes us. If we don’t understand how we learn, we’re likely to make the same mistakes over and over.

5. Looking over doing good. Our evolutionary programming conditions us to do what’s easy over what’s right. After all it’s often easier to signal being virtuous than actually being virtuous. We unconsciously make choices based on optics, politics, and dependability. We hate criticism and seek the validation of our peers and superiors. We often want to feel good about ourselves first and have the outcome we desire second.

Luckily, we can take steps to reduce the odds of stupidity and increase the odds of good decisions in each of these categories.

“The frog in the well knows nothing of the mighty ocean.”

Intelligent Preparation: The World is Multidisciplinary

We live in a society that demands specialization. Being the best means being an expert in something. Letters after your name and decades in the trenches of experience are required before you can claim to know anything. In one sense there is nothing wrong with this — specialized knowledge is required to solve problems and advance our global potential. But a byproduct of this niche focus is that it narrows the ways we think we can apply our knowledge. So we think physicists can’t teach us about love; mathematicians can’t instruct us on how to run a business; poets don’t know squat about “my life.” And bloggers can’t contribute to philosophy. I don’t believe this is true. Knowledge is hard to come by.

It takes work and commitment, and I think we owe it to ourselves to take it out of the box it comes in and experiment with it. We should blow past conformity and apply all the knowledge at our disposal to the problems and challenges we face every day.

Think about it. Over time you’ve picked up a lot of fundamentals about how the world works.

How We Make Decisions

When was the last time you thought about how you make decisions?

If you’re like most people, you’ve never been explicitly taught how to make effective decisions. You make decisions like a golfer who never took any lessons: miserable with the state of your game and yet not seeking to learn a better swing, and instead of hoping for the best every time you lift the club. Hoping that this time your choice will finally work out.

In the early 1980s, Charlie Munger and his partner Warren Buffett realized that a Savings & Loan operation they owned, as with the rest of the industry, was doomed to fail miserably due to forces outside of their control. At a time when almost none of their peers were taking action, they changed course dramatically, massively reducing the effect of the bank’s failure on the rest of their business holdings. These two men knew they had to act much differently than their peers.They saved themselves a great deal of stress and financial pain by applying a uniquely effective system of organized common sense. In hindsight, it seems like an obvious good decision; at the time, it seemed odd and unusual.

The lesson for us is that the people making consistently good decisions take advantage of how the world works. That’s wisdom. Real knowledge of the art of decision making, which remains true across time and circumstances, eras and epochs, can help increase the odds that we get what we want and reduce costly mistakes.

While everyone else is guessing, falling into old patterns, blindly following cognitive biases, we can be clear-headed and laser-focused. Here are some examples of applying — or failing to apply — knowledge about how the world really works.

• It doesn’t matter how smart you are if you don’t realize where things are additive and where they are multiplicative. Nikola Tesla failed to understand Multiplication by Zero when he failed to realize that poor relations with others affected his life. While the Serbian-American was a brilliant inventor, he had difficulty relating to others, which made him difficult to work with. This problem cost him a Nobel Prize and a fortune that today would likely have made him the richest man in the world.
• Understanding and applying the mental model of relativity helped Michael Abrashoff take the worst-performing ship in the US Pacific Fleet and turn it into the best. In his book, It’s Your Ship, he wrote: “The most important skill a skipper can have is the ability to see through the eyes of the crew.”

General Thinking Concepts

Combining intelligent preparation — learning about the big time-tested ideas from multiple disciplines — with general thinking frameworks will dramatically improve your decision-making skills. These thinking frameworks help you look at problems through different lenses.

• Inversion — Otherwise known as thinking something through in reverse or thinking “backwards,” inversion is a problem-solving technique.
• Higher-Order Thinking — Ask yourself, “And then what?”
• The Map Is Not the Territory —The map of reality is not reality itself. If any map were to represent its actual territory with perfect fidelity, it would be the size of the territory itself.

All of these concepts (and six others) can be found in The Great Mental Models Volume 1: General Thinking Concepts.

Books to Improve Decisions

I have compiled a list of 39 of the most helpful books on decision-making. Here are some of my go-to recommendations:

• Judgment and Managerial Decision Making — An academic book that effectively covers heuristics and biases (i.e., how we fool ourselves.) For a non-academic book on the same subject, see Thinking, Fast and Slow by Daniel Kahneman.
• Poor Charlies Almanack and Seeking Wisdom — These books cover most of the ways we fool ourselves but add a layer of applied multidisciplinary education.
• The Great Mental Models Volume 1: General Thinking Concepts — This volume details nine of the most versatile, all-purpose mental models you can use right away to improve your decision-making, productivity, and how clearly you see the world.
