Welcome to the QMAK Mental Models Library, a curated collection of powerful tools and frameworks designed to enhance your thinking, decision-making, and problem-solving abilities. Our library features a wide range of mental models, each offering unique insights and strategies for understanding and interacting with the world around us.
Whether you’re a student, professional, or simply a curious learner, our Mental Models Library provides you with the knowledge and practical guidance to develop a more adaptive, resilient, and effective mindset. We encourage you to explore the different models, apply them to your own experiences, and share your insights with our community of learners.
Triangulation is a mental model that emphasizes the importance of gathering information and perspectives from multiple sources to gain a more comprehensive and reliable understanding of a situation.
Thought experiments are imaginative tools to explore the nature of things, allowing us to simulate scenarios, manipulate variables, and examine outcomes that are impractical to test in reality. 
A powerful brainstorming technique developed by Bob Eberle that offers a systematic way to generate fresh ideas and solutions
A Mental Model coined by psychologist Daniel Kahneman in his 2011 book “Thinking Fast and Slow”. It represents the dual pathways through which we process information, make decisions, and navigate the world around us.
90% of everything is subpar, so use your time and energy wisely. Begin with the top 10% that’s genuinely valuable and cautiously expand from there.
In a nutshell the regret minimization framework is about making decisions that minimize the potential for future regret.
Bayesian thinking is a powerful mental model that uses a probabilistic approach to understand and predict events based on available evidence.
Inversion is a mental model that involves approaching a situation from the opposite end, thinking backward from the desired outcome to the current state. 
The Pareto Principle, also known as the 80/20 rule, suggests that 80% of the effects stem from 20% of the causes. 
Occam’s Razor prioritizes simplicity in explanations, starting with the simplest and adding complexity only when necessary. 
Avoiding attributing to malice what can be explained by ignorance or error helps prevent unnecessary paranoia and encourages a more objective analysis of situations.
This model involves considering the long-term consequences of actions, anticipating ripple effects to make more informed decisions and avoid negative outcomes. 
Reversible decision-making centers on understanding that most choices are not final. Unlike irreversible decisions with lasting impacts, reversible decisions can be easily adjusted or changed as new information or circumstances arise.
This approach emphasizes estimating the likelihood of different outcomes using math and logic. It helps you navigate uncertainty, identify the most probable scenarios, and make more accurate decisions in complex situations. 
Regression to the mean is a statistical concept where extreme or unusual events are usually followed by more normal ones. Essentially, when things stray far from the norm, they tend to return to it over time.
A black swan event is an unexpected occurrence that disrupts conventional data and beliefs, leading people to mistakenly treat these rare events as the norm. However, they should be ignored.
Incentives are rewards or punishments that motivate behavior, whether tangible like bonuses or penalties, or intangible like social recognition or disapproval. 
First Principles Thinking involves breaking down a problem to its fundamental elements, separating core facts from assumptions to reach the essential, irreducible components. 
This powerful idea emphasizes that our representations of reality, whether they be physical maps, mental models, or abstract theories, are not the same as reality itself. 
Humans naturally choose the easiest options, seeking pleasure and avoiding pain. This can lead us to make convenient, but less beneficial choices, like taking the elevator or eating sugary snacks, which can divert us from our long-term goals over time.
Your Circle of Competence is the area where you have deep, comprehensive knowledge, gained through significant time and effort. 
An optimal level of input where the ratio of effort to output is most favorable. It’s the sweet spot where we’re getting the maximum benefit for our investment without wasting time or resources on diminishing returns.
Murphy’s Law, a mid-20th century adage, humorously highlights the inevitability of unforeseen problems, promoting a proactive and prepared mindset. 
Correlation indicates the relationship strength between two variables, measured from -1 to 1. Causation implies a direct cause-and-effect link between them. 
Colin Powell’s 40-70% rule suggests that when making decisions, we should aim to have no less than 40% and no more than 70% of the information we deem necessary.
Parkinson’s Law of Triviality highlights our focus on trivial details over important matters, while Parkinson’s Law states that work expands to fill the available time. 
Combining the words “satisfy” and “suffice,” Satisficing is about prioritizing needs over desires and finding satisfaction in choices that meet our essential criteria.
