Chances are that you've heard the term “mental models” before, but do you understand what they are and how you can use them to help organize your thoughts? In this article, we’re taking a closer look at the framework of mental models and what you can do to make them work for you.
It's no secret that the way we think plays a crucial role in how much success and satisfaction we can achieve. Having a structured approach to organizing those thoughts can help you get better results and make more meaningful decisions. This is where mental models come in.
Psychologist George A. Miller defines mental models as "internal cognitive structures that represent the complexities of external reality selectively and incompletely". In essence, they help us organize our thoughts and make sense of the world around us.
Mental models allow us to make sense of large bodies of information by boiling them down to simpler ideas. For example, if you're trying to understand the dynamics of a certain business market, you could use the PESTLE framework, which looks at the political, economic, social, technological, legal, and environmental factors that may shape the market.
By doing this, you're able to break down a complex problem into smaller, more manageable pieces that you can analyze and process. You're also able to identify relationships between different factors and draw bigger-picture conclusions.
Another benefit of using mental models is that they provide a better framework for decision-making. Your decisions will be better informed and more thoughtful if you approach them by first looking at the specific model you are using and then evaluating it in the context of the problem you are trying to solve.
Mental models also make it easier to explain ideas to others in a clear and concise manner. By having a common frame of reference, you’ll be able to communicate with greater precision and clarity.
Types of Mental Models
There are countless mental models that you can use to lay out your thoughts. However, some of the most popular categories include:
Economic models, which help you understand market dynamics and how different economic forces interact with one another.
Scientific models, which help you visualise concepts like evolution, gravity, and electricity.
Organizational models, which help you think about groups of people, such as teams, companies, or governments.
Decision-making models, which help you make the best choices based on the information available to you.
Psychological models, which help you understand behavior and build better relationships with people.
The Benefits of Using Mental Models
Using mental models gives you a great platform for structuring and organising your thoughts in a more logical and effective way. It allows you to break down complex problems into more manageable pieces and also helps you explain ideas to others in a clear and concise manner. Plus, it has the potential to provide better insight into decision-making, enabling you to make more informed and thoughtful choices.
In addition, having an increased awareness of mental models enables you to think more critically about your own knowledge. By understanding how certain models may shape your beliefs and assumptions, you can begin to challenge your own understanding and evaluate your decisions for themselves.

It can also help you to identify and overcome cognitive biases, like confirmation bias and the availability heuristic. By understanding how mental models can influence your decision-making, you can begin to recognize and avoid common pitfalls and make more sound mental decisions.
Finally, by having a better awareness of mental models, you can make the most of your resources. By utilizing the available knowledge more efficiently, you can increase your productivity and optimize your day-to-day operation.
How to Get Started With Mental Models
Learning more about mental models is a great way to become more efficient in your thinking and decision-making. The best way to get started is to pick a few models and start applying them to your everyday thinking.
Start small and work your way up. Investigate different models and try to understand how each one works. For example, try to break down the PESTLE model and examine how the different elements interact with one another. Focus on one model at a time and practice using it.
Once you become more comfortable with how the models work, you can start to think about how they can apply to different areas of your life. For example, you can use the PESTLE framework to analyse a business problem or try to apply scientific models to explore a potential new technology.
You can also apply mental models to situations outside of work. For example, the 5 Whys technique is a popular decision-making process used by many successful companies. You can apply that same process to your everyday life to help you get to the root of any decision or problem you may have.
You can also use mental models to help you brainstorm new ideas. Instead of mindlessly coming up with random ideas, try to use a mental model to frame the problem and generate new solutions.
Finding the Right Models for You
The key to getting the most out of mental models is to find the ones that work best for you. Not all models are created equal and different models work better for different situations.
It’s also important to remember that mental models are not a one-size-fits-all solution. You should tailor the models to your particular situation and use them as a tool to help you explore and analyze the problem.
That being said, there are some mental models that are popular across many fields and types of problems. The PESTLE framework is an example of such a model. Other popular models include AIDA (Attention, Interest, Desire, and Action), SWOT (Strengths, Weaknesses, Opportunities, and Threats), and the RACI (Responsible, Accountable, Consulted, and Informed) model.
Once you’ve identified the models that are best suited to your needs, you can start to practice using them. Keep track of the models you’ve used and how they have helped you to solve problems. Refine your process and build on the models that you find most effective.
Conclusion
Using mental models is a great way to increase your efficiency and improve your decision-making skills. By understanding how they work and how to apply them to your life, you’ll be able to get the most from your resources and maximize your productivity.
Start by researching the types of mental models and identifying the ones that are most applicable to your needs. Practice using them in different situations and experiment with different models to see what works best for you. With a bit of practice, you’ll soon find that you’re able to efficiently solve problems and make better decisions with the help of mental models.
