Any action you take generates some type of feedback. The result can be monumental or tiny, desirable or undesirable, expected or wildly surprising. If you’re paying attention, you might notice what happens after you do something and use that feedback to determine what to do next. If you’re driving along a snowy road and your car begins to skid, the skid lets you know conditions require some type of adjustment. You don’t want to get into an accident, so you slow down. Maybe you slow down intentionally, but maybe you’ve done this a thousand times and adjust your speed automatically without even noticing.
Your brain has criteria for evaluating the data provided by physiological feedback loops (in order to maintain your body temperature and signal when you need to eat or drink—or stop eating or drinking). It also has criteria for evaluating the data provided by your mental, emotional, and behavioral feedback loops. The problem is that these criteria are part of your mental model of the world, much of which is unconscious, which means you’re not aware of it.
David DiSalvo calls feedback loops “the engines of your adaptive brain.”
Day in and day out, we make decisions based on the results of feedback loops that run in our minds without our noticing. None of us stops to think through each stage of the loop—how the data we’ve gathered is being processed to lead us to our next action. And yet, even without our conscious monitoring, the loops just keep moving.
The Four Stages of a Feedback Loop
Science writer Thomas Goetz described feedback loops in Wired Magazine:
Evidence
First comes the data: A behavior must be measured, captured, and stored.
Relevance
Second, the information must be relayed to the individual, not in the raw-data form in which it was captured but in a context that makes it emotionally resonant.
Consequence
But even compelling information is useless if we don’t know what to make of it. The information must illuminate one or more paths ahead.
Action
There must be a clear moment when the individual can recalibrate a behavior, make a choice, and act.
After that action is measured, the feedback loop can run once more, every action stimulating new behaviors that inch us closer to our goals.
As DiSalvo says, we make decisions based on the results of feedback loops, but even in cases where we’re making decisions rather than simply reacting, it would be more accurate to say we make decisions based on our interpretation of the results of feedback loops. The apparent result of an action we’ve taken—the evidence—has to be interpreted for relevance and consequence before we can determine how to react.
Your brain does not necessarily objectively evaluate the data presented to it. Because you perceive the world through your particular mental model, you’re predisposed to interpret the results of your actions in certain ways. This can be problematic especially when you’re presented with negative evidence. Things didn’t work out the way you planned; you did something other than what you intended or wanted to do; or you’re faced with unexpected obstacles. The most useful way to respond to such information is to look at it objectively: you tried something and it didn’t work. You can then try to figure out why it didn’t work and decide whether to try it again or to do something else.
Your Brain Prefers to Maintain the Status Quo
Let’s say you normally dine out with a group of friends once a week at which time you tend to overindulge a bit. You’ve now decided to cut back on the calories and have a vague idea of ordering something from the lighter side of the menu. But once you’re at the restaurant, menu in hand, you find yourself quickly scanning the lower-calorie items and then ordering what you always order.
You’re disappointed in yourself, especially when you think about it afterward. You’ve had similar experiences before, so you interpret it as just another example—more proof—of how little willpower you have.
Confirmation bias is powerful. If you believe you lack willpower, you’re likely to view the negative results of your actions as confirmation of your preexisting belief. Once you interpret your result as proof of a preexisting belief, you’re much less likely to attempt to figure out what didn’t work and what to do next and much more likely to give up. At that point, the habit or behavior you were trying to change becomes even more entrenched and the goal you were trying to achieve seems even more distant.
But if you looked at this situation objectively, in terms of gathering data (feedback) so you could decide what to do next time, you might see it differently.
You might remind yourself that your brain prefers to maintain the status quo. So when you went to a familiar restaurant where all the familiar cues and triggers kicked in, the result you got—ordering the usual—was really quite predictable. The feedback to store is that going into this situation with a vague idea but no plan doesn’t work. Next time, you could try deciding ahead of time what you’re going to order so you don’t have to be tempted by the menu. If that doesn’t work, you could suggest meeting your friends at a different restaurant that doesn’t have the same kind of food-related associations.
How you perceive and interpret what happens after you take, attempt to take, or fail to take action strongly affects your chances of success. Not everything you try is going to go smoothly or work out the way you hoped it would. Sometimes the road is slippery, under construction, or takes a detour. Noticing that what you tried simply didn’t work will allow you to use the information to help you determine the best action to take next—as will noticing when what you tried did work.
