5.3 Synthesize the situation through time.
To see how the dots connect through time you must collect, analyze, and sort different types of information, which isn’t easy. For example, let’s imagine a day in which eight outcomes occur. Some are good, some bad. Let’s illustrate this day with each type of event represented by a letter and the quality of the outcome represented by its height.
In order to see the day this way, you must categorize outcomes by type (signified by letters) and quality (the higher up the graph, the better), which will require synthesizing a by-and-large assessment of each. (To make the example more concrete, imagine you’re running an ice cream shop and the W’s represent sales, the X’s represent customer experience ratings, the Y’s represent press and reviews, the Z’s represent staff engagement, etc.) Keep in mind that our example is a relatively simple one: just eight occurrences over one day.
People who are good at pulling out such patterns of events are rare and essential, but as with most abilities, synthesizing through time is only partially innate; even if you’re not good at it, you can get better through practice. You’ll increase your chances of succeeding at it if you follow the next principle.
a. Keep in mind both the rates of change and the levels of things, and the relationships between them.
When determining an acceptable rate of improvement for something, it is its level in relation to the rate of change that matters. I often see people lose sight of this. They say “it’s getting better” without noticing how far below the bar it is and whether the rate of change will get it above the bar in an acceptable amount of time. If someone who has been getting grades of 30s and 40s on their tests raised their scores to 50s over the course of a few months it would be accurate to say that they are getting better, but they would still be woefully inadequate. Everything important in your life needs to be on a trajectory to be above the bar and headed toward excellent at an appropriate pace. The lines in the chart below show how the dots connect through time. A’s trajectory gets you above the bar in an appropriate amount of time; B’s does not. To make good decisions, you need to understand the reality of which of these two cases is happening.
b. Be imprecise.
Understand the concept of “by-and-large” and use approximations. Because our educational system is hung up on precision, the art of being good at approximations is insufficiently valued. This impedes conceptual thinking. For example, when asked to multiply 38 by 12, most people do it the slow and hard way rather than simply rounding 38 up to 40, rounding 12 down to 10, and quickly determining that the answer is about 400. Look at the ice cream shop example and imagine the value of quickly seeing the approximate relationships between the dots versus taking the time to see all the edges precisely. It would be silly to spend time doing that, yet that’s exactly what most people do. “By-and-large” is the level at which you need to understand most things in order to make effective decisions. Whenever a big-picture “by-and-large” statement is made and someone replies “Not always,” my instinctual reaction is that we are probably about to dive into the words—i.e., into a discussion of the exceptions rather than the rule, and in the process we will lose sight of the rule. To help people at Bridgewater avoid this time waster, one of our just-out-of-college associates coined a saying I often repeat: “When you ask someone whether something is true and they tell you that it’s not totally true, it’s probably by-and-large true.”
c. Remember the 80/20 Rule and know what the key 20 percent is.
The 80/20 Rule states that you get 80 percent of the value out of something from 20 percent of the information or effort. (It’s also true that you’re likely to exert 80 percent of your effort getting the final 20 percent of value.) Understanding this rule saves you from getting bogged down in unnecessary detail once you’ve gotten most of the learning you need to make a good decision.
d. Be an imperfectionist.
Perfectionists spend too much time on little differences at the margins at the expense of the important things. There are typically just five to ten important factors to consider when making a decision. It is important to understand these really well, though the marginal gains of studying even the important things past a certain point are limited.
