“What the pupil must learn, if he learns anything at all, is that the world will do most of the work for you, provided you cooperate with it by identifying how it really works and aligning with those realities. If we do not let the world teach us, it teaches us a lesson.”
— Joseph Tussman
The first thing they always do is tell you what they think. When someone has an opinion about everything, they want to share it with you. They often tout stats and research as if they had an imaginary checklist of facts they need to be able to rattle off to establish themselves as an expert in a field they actually know very little about. Because they have an opinion on everything, they are quick to judge others – for their lack of opinions, for their lack of knowledge, for their lack of outrage … the list goes on.
I'm a firm believer that you can learn something from everyone. Sometimes that effort is more time-consuming than others. People who have opinions about everything barf so much noise that it's hard to find the signal. Your brain has to work overtime to figure out if they did the work to come up with their opinions themselves or if they're simply regurgitating some op-ed in a newspaper. Over time, opinionated people also end up in their own prisons and they try to take you with them.
The problem comes from how we see the world. Our opinions are often rooted in how we think the world should work, according to our morals, values, and principles. If we see the world through the lens of our opinions, much of what happens will not agree with us. This is feedback, and how we respond to this feedback is key.
The world never tells you that you're wrong; it only gives you outcomes.
When an outcome is not what you want it to be, things get tough. You can ignore the result and continue to think that you're right. This protects your ego. It also carries the risk of your continuing to believe something that isn't true. Alternatively, you can calibrate your believability on the subject at hand by lowering the odds that you're right. For example, maybe you gave yourself an 85 out of 100 for the ability to hold a firm opinion on this subject, and now you lower your score to 75. If the world continues to provide undesirable outcomes, eventually you get the hint and change your beliefs. Finally, you can give up your opinions and just respond to the world as it is. This option is the hardest.
People who can't change their minds never move forward. Worse still, they see themselves as heroes. And I mean “heroes” in the Hollywood sense. They hold opinions that have been proven wrong over and over again. And they pay a dear price.
They stop getting promoted. Their work colleagues avoid them. Their friends call less often. Their disagreeable dispositions mean that people don't want them around. They are prisoners of their beliefs. They want everyone to see that they're right. If they persist long enough, the only people they have in their circles are people who have the same (incorrect) worldview.
If you insist on having an opinion, carry a mental scorecard. Start it with 50/50 on all subjects and adjust it based on outcomes. Use a decision journal. When you're right – and “right” means that you're right for the right reasons – you raise your score. When you're wrong, lower the score. Over time, you'll calibrate your circle of competence.
If that sounds like a lot of work, just say, “I don't have an opinion on that; why don't you tell me how you got to have such a firm one? It sounds like I could learn something.”
