As you move through the world, you probably have the sense that you’re aware of whatever there is to be aware of as it is. This applies not only to the sensory world, but also to events, situations, interpersonal interactions—actually to everything that exists or occurs within your world. But the capacity of conscious attention is much too limited for this to even be possible. The 11,000,000 bits of information being processed by the unconscious part of the brain at any given moment need to be considerably (and swiftly) condensed and summarized into the 40 bits you can process consciously.
Consciousness is a way of projecting all the activity in your nervous system into a simpler form. [It] gives you a summary that is useful for the larger picture, useful at the scale of apples and rivers and humans with whom you might be able to mate. —David Eagleman, Incognito
What You See Is All There Is (WYSIATI)*
Your brain maintains a model of the world that represents what’s normal in it for you. The result is that you experience a stripped-down, customized version of the actual world. To a great extent, each of us really does inhabit our own world. But it would be incorrect to say that we create our reality; rather, our brain creates our reality for us.
Much, if not most, of what you do, think, and feel consists of automatically generated responses to internal or external stimuli. And it isn’t possible to consciously mediate all of your responses. It wouldn’t even be a good idea to try.
In addition to helping you navigate the world, your mental model gives rise to your sense of the way things should be. It generates expectations (that are either confirmed or denied), assumptions, biases, etc. that determine what you pay attention to, what you perceive (even what you are able to perceive), how you interpret and respond to what you perceive, and the meaning you make of it all. Your mental model is the result of your genes and your experiences, of both intention and accident. Your brain has been constructing your particular model of the world since your birth, and it is continually updating and modifying it—most of the time entirely outside your awareness.
But while the contents of your particular mental model determine what you think, feel, do, and say, you can’t search them—or follow a bread-crumb trail backward through them—to find out precisely which aspects (and when and how they came to be) give rise to any specific facet of who you are and how you react now.
The significance of your mental model in your life can’t be overstated. Although you aren’t consciously aware of it, your mental model circumscribes not only every aspect of your present experience but also what is possible for you to do and be. It determines what you see and how you see the world, both literally and figuratively, as well as how you see yourself.
But…Your Brain Can Get It Wrong
System 1, the unconscious part of your brain, uses associative thinking to develop and maintain your model of the world. However, there are some problems with associative thinking. For example:
- It sacrifices accuracy for speed.
- It doesn’t discriminate very well.
- It takes cognitive shortcuts (aka cognitive biases).
Your mental model can—and sometimes does—lead to erroneous conclusions and inappropriate responses. It’s the job of consciousness (System 2) to check the impulses and suggestions it receives from System 1, but consciousness is slow, lazy, and easily depleted. Most of the time, it’s content to go along with System 1, which means it’s susceptible to cognitive biases. By definition, cognitive biases are distortions or errors in thinking. They actually decrease your understanding while giving you a feel-good sense of cognitive ease.
Confirmation bias is the easy acceptance of information that validates what you already believe. It causes you to selectively notice and pay attention to what confirms your beliefs and to ignore what doesn’t. It underlies the discomfort you feel around people who disagree with you and the ease you feel around people who share your beliefs.
Information that confirms what you already believe to be true makes you feel right and certain, so you’re likely to accept it uncritically. On the other hand, you’re more likely to reject information that is inconsistent with what you already believe or at least you hold inconsistent information up to greater scrutiny. You have different standards for evaluating information depending on the level of cognitive ease it generates.
Evidence has precious little impact on any of us if it conflicts with what we believe simply because the cognitive strain of processing it is too great. To a very real extent, we don’t even “see” conflicting evidence. While total commitment to our particular worldview (mental model) makes us feel more confident, it narrows—rather than expands—our possibilities. That means it limits our powers of discernment, our ability to increase our understanding of the world around us, and our creative potential. It closes the world off for us instead of opening it up.
The often-quoted statement is true: we don’t see things as they are; we see them as we are. If we want to live fuller lives, if we want to be more effective or useful or loving in the world, we first need to recognize that our greatest constraints are imposed by our own mental models.
It’s important to remember that what you see is not all there is.
