Use evidence-based decision-making tools. These principles were designed to help you get control over your lower-level/animal you and put your better, higher-level decision-making brain in charge.
What if you could unplug that lower part of your brain entirely and instead connect with a decision-making computer that gives you logically derived instructions, as we do with our investment systems? Suppose this computer-based decision-making machine has a much better track record than you because it captures more logic, processes more information more quickly, and makes decisions without being emotionally hijacked. Would you use it? In confronting the challenges I’ve faced in the course of my career I’ve created exactly such tools, and I am convinced that I would not have been nearly as successful without them. I have no doubt that in the years ahead such “machine-thinking” tools will continue to develop and that smart decision-makers will learn how to integrate them into their thinking. I urge you to learn about them and consider using them.
Know when it’s best to stop fighting and have faith in your decision-making process. It’s important that you think independently and fight for what you believe in, but there comes a time when it’s wiser to stop fighting for your view and move on to accepting what believable others think is best. This can be extremely difficult. But it’s smarter and ultimately better for you to be open-minded and have faith that the consensus of believable others is better than whatever you think. If you can’t understand their view, you’re probably just blind to their way of thinking. If you continue doing what you think is best when all the evidence and believable people are against you, you’re being dangerously arrogant.
The truth is that while most people can become radically open-minded, some can’t, even after they have repeatedly encountered lots of pain from betting that they were right when they were not. People who don’t learn radical open-mindedness don’t experience the metamorphosis that allows them to do much better. I myself had to have that humility beaten into me by my crashes, especially my big one in gaining open-mindedness doesn’t mean losing assertiveness. In fact, because it increases one’s odds of being right, it should increase one’s confidence. That has been true for me since my big crash, which is why I’ve been able to have more success with less risk.
Becoming truly open-minded takes time. Like all real learning, doing this is largely a matter of habit; once you do it so many times it is almost instinctive, you’ll find it intolerable to be any other way. As noted earlier, this typically takes about eighteen months, which in the course of a lifetime is nothing.
For me, there is really only one big choice to make in life: Are you willing to fight to find out what’s true? Do you deeply believe that finding out what is true is essential to your well-being? Do you have a genuine need to find out if you or others are doing something wrong that is standing in the way of achieving your goals? If your answer to any of these questions is no, accept that you will never live up to your potential. If, on the other hand, you are up for the challenge of becoming radically open-minded, the first step in doing so is to look at yourself objectively.
One way to do this is by asking questions like “Would you rather I be open with my thoughts and questions or keep them to myself?”; “Are we going to try to convince each other that we are right or are we going to open-mindedly hear each other’s perspectives to try to figure out what’s true and what to do about it?”; or “Are you arguing with me or seeking to understand my perspective?”
Psychologist and science journalist Daniel Goleman originally coined this term in Emotional Intelligence.
Some of this may be a result of what is called the Dunning-Kruger effect, a cognitive bias in which low-ability individuals believe that they are in fact superior.
Understand That People Are Wired Very Differently
Because of the different ways that our brains are wired, we all experience reality in different ways and any single way is essentially distorted. This is something that we need to acknowledge and deal with. So if you want to know what is true and what to do about it, you must understand your own brain.
