A mental model is a representation of how something works. Our brain isn’t made to store too much information, so we use models to compartmentalise reality to make it manageable to the ego. These models are essential to reasoning, sense-making and logic.
The quality of our thinking is proportional to the range of mental models. If you have a more comprehensive range of tools, you can solve more problems; the same with mental models and making sense of reality.
