In a recent encounter with my C-suite executive, I was encouraged to adopt a more systematic approach to problem-solving by incorporating frameworks into my thinking process. This suggestion prompted me to delve deeper into the distinction between mental models and framework thinking, concepts I had previously used interchangeably. Intrigued by the feedback, I embarked on a journey to comprehensively understand these methodologies and integrate them into my daily decision-making toolkit. In this endeavor, I aim to clarify these concepts in simple terms without jargon.
Mental models serve as cognitive tools that aid in comprehending the intricacies of the world around us. Conversely, framework thinking employs structured methodologies to dissect problems and make informed decisions. While individual experiences and learning primarily shape mental models, frameworks offer formalized structures for analysis and decision-making. To draw an analogy, mental models act as lenses through which we perceive the world, while framework thinking provides systematic approaches to problem-solving.
Renowned researcher Shane Parrish has extensively studied mental models, documenting over 100 of them and categorizing them into distinct bins to enhance usability. These categories span various domains, including core thinking concepts, physics and chemistry, biology, systems, numeracy, microeconomics, military and war, and human nature and judgment.

On the other hand, frameworks serve as factual or conceptual structures for constructing solutions to complex problems. Framework thinking encompasses a conceptual approach or methodology for analysis, pattern recognition, and decision-making. Leading management consulting firms and prominent thinkers often share frameworks tailored to specific scenarios, establishing their brands. Leveraging existing frameworks eliminates the need to create new ones. I have begun categorizing them into industry segments, a list that continues to evolve and expand.
Understanding the application of mental models and framework thinking in practical scenarios is paramount. I have distilled the process into four simple steps, acknowledging that it may evolve:
- Recognize suitable events or signals that warrant attention.
- Identify patterns within these events to gain insights.
- Utilize relevant mental models to dissect problems from different perspectives.
- Employ framework thinking to articulate and address the problem systematically.
While these steps may appear straightforward, recognizing suitable events requires a honed skill developed through experience or street smarts, akin to distinguishing between signal and noise. Subsequently, identifying patterns and selecting or constructing appropriate frameworks are crucial steps in devising practical solutions.
In conclusion, this article is a preliminary exploration of mental models and framework thinking. In subsequent installments, I will delve deeper into practical applications and real-world examples to explain their efficacy in problem-solving and decision-making.
