This was driven home to me by my son Paul’s three-year struggle with bipolar disorder. As terrifying and frustrating as his behavior was, I came to realize that it was due to his brain’s chemistry (specifically, its secreting serotonin and dopamine in spurts and sputters). As I went through that terrible journey with him, I experienced the frustration and anger of trying to reason with someone who wasn’t thinking well. I constantly had to remind myself that there was no basis for my anger because his distorted logic was a product of his physiology, and I saw for myself how the doctors who approached it that way brought him to a state of crystal clarity. The experience not only taught me a lot about how brains work but why creative genius often exists at the edge of insanity. Many highly productive and creative people have suffered from bipolar disorder, among them Ernest Hemingway, Beethoven, Tchaikovsky, Vincent van Gogh, Jackson Pollock, Virginia Woolf, Winston Churchill, and the psychologist Kay Redfield Jamison (who has written frankly about her own experiences with the disease in her book An Unquiet Mind). I learned that we are all different because of the different ways that the machine that is our brain works, and that nearly one in five Americans are clinically mentally ill in one way or another.
Once I understood that it’s all physiological, many things became clearer to me. While I used to get angry and frustrated at people because of the choices they made, I came to realize that they weren’t intentionally acting in a way that seemed counterproductive; they were just living out things as they saw them, based on how their brains worked. I also realized that as off-base as they seemed to me, they saw me the same way. The only sensible way of behaving with each other was to look down upon ourselves with mutual understanding so we could make objective sense of things. Not only did this make our disagreements less frustrating, it also allowed us to maximize our effectiveness.
Everyone is like a Lego set of attributes, with each piece reflecting the workings of a different part of their brain. All these pieces come together to determine what each person is like, and if you know what a person is like, you’ll have a pretty good idea of what you can expect from them.
We are born with attributes that can both help us and hurt us, depending on their application. Most attributes are a double-edged sword that bring potential benefits and potential harm. The more extreme the attribute, the more extreme the potential good or bad outcomes it is likely to produce. For example, a highly creative, goal-oriented person good at imagining new ideas might undervalue the minutiae of daily life, which is also important; he might be so driven in his pursuit of long-term goals that he might have disdain for people who focus on the details of daily life. Similarly, a task-oriented person who is great with details might undervalue creativity, and worse still, may squelch it in the interests of efficiency. These two people might make a great team, but are likely to have trouble taking advantage of the ways they’re complementary, because the ways their minds work make it difficult for them to see the value of each other’s ways of thinking.
Having expectations for people (including yourself) without knowing what they are like is a sure way to get in trouble. I learned this the hard way, through years of frustrating conversations and the pain of expecting things from people who were constitutionally incapable of delivering them. I’m sure that I caused them plenty of pain too. Over time, I realized that I needed a systematic approach to capturing and recording our differences so that we could actively take them into consideration when putting people into different roles at Bridgewater.
This led to one of my most valuable management tools: Baseball Cards, which I mentioned in the first part of this book. Just as a baseball card compiles the relevant data on a baseball player, helping fans know what that player is good and bad at, I decided that it would be similarly helpful for us to have cards for all of our players at Bridgewater.
