In the 1999 action movie The Matrix, the character Neo is offered a choice by the mysterious Morpheus. The choice is more challenging than it might initially appear. Watching the movie, we all want our hero to make the choice that he inevitably does because that is going to make a much more interesting story.
This scene provides us with a useful and interesting analogy. To see why this is, I am going to start by asking you some questions.
In the following categories, are you unlimited or are you limited?
- Knowledge (do you know all there is to know)
- Wisdom (can you apply that knowledge without error, practically and with a perfect understanding of context and long range consequences in every situation)
- Skill (are you right now as skilled as a person can be in any domain)
- Senses / Perception (can you perceive / sense everything that is affecting you in your environment from moment to moment and hold those perceptions in your awareness while recognizing their relevance to the categories above)
When you think of it like that, it seems obvious. All of us, as human beings, are limited. We cannot even process all of the information coming in from our already limited senses at one time. In fact, even our ability to pay attention to the data that is coming in is finite. Stage magicians use this fact regularly in their performances by managing our attention away from that which they don’t want us to notice in order to accomplish their tricks.
Because of these limitations, all of us develop belief structures modern psychologists refer to as Mental Models (sometimes referred to as Mental Representations) in order to function efficiently in day-to-day life.
To further explore this important idea:
Mental models are personal, internal representations of external reality that people use to interact with the world around them. They are constructed by individuals based on their unique life experiences, perceptions, and understandings of the world. Mental models are used to reason and make decisions and can be the basis of individual behaviors. They provide the mechanism through which new information is filtered and stored…
…Because of cognitive limitations, it is neither possible nor desirable to represent every detail that may be found in reality. Aspects that are represented are influenced by a person’s goals and motives for constructing the mental model as well as their background knowledge of existing knowledge structures, which, as noted above, may be conceptualized as ‘mental models existing in long term memory’. Mental models thus play a role in filtering incoming information. The theory of ‘confirmation bias (Klayman and Ha 1989) suggests that people seek information that fits their current understanding of the world. Incoming information may reinforce existing mental models or may be rejected outright. (2)
These quotes are from published studies, so they use some complicated language, but they are useful to demonstrate some of the commonly held (widely agreed upon) principles that make up the definition as I use it in my writing. Let’s simplify a bit by breaking down what you just read.
Mental Models:
(From the first half)
- Are personal – This means they are unique to each of us
- Are internal – They are in our minds
- Are representations of external reality – They reflect our current understanding of reality; they are not objective reality itself.
- Are constructed from our unique life experiences, perceptions, and understanding of the world and the environment we live in – None of us comes into this life with full contextually relevant understanding or skill in any subject. We learn and we grow throughout our lives. Our Mental Models are the stories we tell ourselves about how the world works. Example: A robust Mental Model that is pretty consistent with most human beings is that “gravity points down”. This is because we all experience this from an early age. Having the flexibility to create or modify models can be seen in the example of an astronaut. For someone working on the International Space Station for several months, gravity pointing down will be less useful during their stay in a “zero-g” environment.
- Are used to reason and make decisions. They can also be the basis of individual behaviors. – This shows both the conscious and pre-conscious impact of our Mental Models. Much of our behavior happens at a pre-conscious level (more on this in future articles). The more sophisticated our Models are, the greater accuracy our perceptions and the more effective our choices and behaviors are.
- Are influential to the way we filter and store new information. – Mental Models not only influence what we know, but how we know it / how we learn / how we understand the new information coming in from our environment.
(From the second half)
- We all have natural cognitive limitations as human beings. – Not a single one of our Mental Models is a complete or accurate representation of objective reality.
- Goals and motives influence our models as well as our current understanding – As seen above, not only does our understanding of our experiences influence our behavior, but it also influences our relationship with new data coming in (how and where it is stored and filtered as it comes in).
- Confirmation Bias (https://www.britannica.com/science/confirmation-bias ) , the Dunning-Kruger effect (https://www.psychologytoday.com/us/basics/dunning-kruger-effect ) , etc. reflect some of the dangers of losing site of these principles.
Let’s take a quick look at some of the ramifications of these points we have outlined.
Each of us as human beings is unique. In all of history, there is no other person that has had the same life experiences, perceptions, and therefore developed the same understanding of reality as you have. Mental Models are personal, internal subjective representations of objective reality. There are certainly many common elements in shared models. Think of the example of our shared model of how gravity works we mentioned above. With that said, there are also going to be differences. Models will vary with the experiences, culture, etc. that shaped them. One important take away for this is to realize that everyone does not share your models or think about any given topic the way you do.
Another important factor to remember is that every model you have is incomplete. This realization opens the door for the humility necessary to learn or to adapt to a changing environment in an effective way. When this is forgotten, it is easy to slip into something psychologists call “cognitive bias”. We have all ignored or forced information coming in from our senses fit our existing models rather than updating the models when the information is in conflict with our assumptions.
All models are wrong, but some are useful – George E. P. Box
models are wrong, but some are useful – George E. P.
With these ramifications in mind, think about the importance of developing a number of different interrelated models and recognizing the value of updating them and switching which lens you are looking through as you make observations in any given circumstance.
One of the foremost strategic thinkers of our time, Colonel John Boyd wrote about the importance of this idea in his essay Destruction and Creation (September 1976). In the essay, Boyd linked concepts and principals found in seemingly unrelated fields of mathematical logic, physics, and thermodynamics. He linked Godel’s Incompleteness Theorem, Heisenberg’s Uncertainty Principal, and the 2nd Law of Thermodynamics to make his point (as well as adding arguments of Polanyi, Popper, and Kuhn). Frans Osinga said of Destruction and Creation:
“The heart of the essay is the discussion about the nature of knowledge…
Boyd saw that adaptability was a key survival trait. He recognized that every Mental Model we developed was outdated as soon as we created it. Not only is our understanding of the infinite complexity of our situation limited, but every action we or others take makes changes to the rapidly evolving situation. Since it is impossible to fully understand every important detail in the moment, the ability to rapidly revise your Mental Models becomes crucial to survival.
“Although it is tempting to believe that upon knowing how the expert does something, one might be able to “teach” this to novices, this has not been the case [e.g., Klein & Hoffman, 1993]. Expertise is a long term developmental process resulting from rich instrumental experiences in the world and extensive practice. These cannot simply be handed to someone.” (4)
In another great scene from that movie that illustrates this idea, Neo is in “training” and is downloading a bunch of different programs directly into his brain. Through the magic of Hollywood storytelling this is somehow possible. He opens his eyes and declares “I know Kung Fu”. Morpheus responds “Show me” and the two enter a virtual dojo sparring program. Even though, theoretically, Neo has more raw talent and he now “knows” all the moves from the styles he has been “studying”, Morpheus handily kicks his butt in the sparring program. Morpheus has experience. He sees Neo’s potential and is trying to bring it out. Although Neo had more in the way of “raw talent” to work with, it was insufficient when measured practically against Morpheus’ greater experience at applying his skills in the environment they were competing in.
