Yes, I appreciate the irony and meta nature of having a mental model to explain mental models but… well, I'm going there.
Mental Models are simplified representations, concepts, and frameworks that allow us to quickly understand ourselves and our world.
AN INSTINCTIVE TOOL FOR A COMPLEX WORLD.
Mental Models ultimately exist because our world and life are incredibly complex, and our brains have limited ability to hold that complexity — so we make sense of everything and act in the world with the cognitive shortcuts that are Mental Models.
Everyone uses Mental Models to simplify and understand everything, all the time. They define the way you interpret, prioritise, decide, anticipate, predict, and engage with the world and yourself.
APPLICATIONS.
Mental Models have been discussed and used in a number of fields.
- Psychology and philosophy: mental models refer to mental representations or imagery;
- UX design and usability: mental models are a key tool in understanding user assumptions, behaviour and expectations;
- Education: mental models are used to understand prior knowledge and build on a learner's existing conceptual framework.
- Learning and performance: mental models were identified by Peter Senge as one of five key ingredients of a learning organisation.
- Business: Charles Munger and the Latticework of Models approach that lies behind ModelThinkers, has applied and expanded upon this basic understanding to create greater impact in the business world.
MENTAL MODELS AND MODELTHINKERS.
Here at ModelThinkers, we take a broad view of the definition of mental models, as you can see by exploring our site and we have been absolutely inspired by Charles Munger's approach to building a Latticework of Mental Models.
Finally, it's important to understand the limitations of Mental Models which you can read about more in the Map versus Territory model, and in the limitations section we've included in every model summary




- Bring awareness to your mental models.
Metacognition is the process of ‘thinking about thinking’, and is an important part of developing high performance in any domain. This includes reflecting on what your current mentals models are in any situation, challenge or decision.
- Remember that the Map is not the Territory.
We’ve dedicated a mental model to this here, but the point is that all mental models are merely representations of reality. It’s important to remember that all mental models are ultimately wrong and that several, even opposing, mental models might have elements of truth at the same time.
- Understand other people’s mental models.
Appreciate that other people won’t necessarily share your mental models and will interpret a situation differently. Rather than assuming that they are wrong, ask questions to better understand the mental models that led to that understanding, then challenge your own mental models with that understanding.
- Consciously build and apply a latticework of mental models.
This is the point of ModelThinkers and is covered more by the Munger’s Latticework of Mental Models.
The blind men and the elephant.
In the parable of the blind men and an elephant, a group of blind men come across an elephant, having no existing experience (and therefore mental models) of what an elephant is. They each reach out, touching a different part of the elephant. One touches the tusk and says “this is a thick snake.” Another touches it’s ear and claims that it is a fan.
Plato’s cave.
The allegory of the cave by Plato described prisoners chained in a cave who can only see a wall. On the wall is the projected shadows of activity of people behind them. They never see the actual people, just the shadows — which they mistake for reality.
In this sense, shadows can be seen as metaphors for mental models — an interpretation of reality. However, the parable is more generally used to make a distinction between trusting our senses versus philosophical reasoning.
The desktop on your computer.
Want a more grounded example? Consider how computers make use of the desktop metaphor to explain how ‘files’ fit in ‘folders’ and how to navigate options within a digital environment. This metaphor leverages existing metaphors of a real-world workspace to present a meaningful and efficient user experience.
The main limitation of mental models is that they are not reality, as explored by the Map vs Territory.
Mental models are the underlying model that informs everything in this site, so in that sense it’s linked to everything. That said, the two models to particularly consider in relation to it are Munger’s latticework and map vs territory.
The concept behind mental models were explored by philosopher and mathematician Charles Pierce in 1896, who incorporated a ‘diagram’ or representation of things as part of a broader reasoning process. After that, in 1927, Georges-Henri Luquet argued that children construct ‘internal models’.
The idea of mental model was explicitly referred to by Kenneth Craig in his 1943 book, The Nature of Explanation where he described the mind creating “small scale models.”
The term ‘mental models’ came to the fore in 1983 when Phil Johnson-Laird published a book called Mental Models: Towards a Cognitive Science of Language, Inference and Consciousness.
