Charlie Munger's mental models
Back in November, Charlie Munger, the legendary vice chairman of Berkshire Hathaway (Warren Buffet's investing powerhouse), passed away at the age of 99, leaving a profound impact on the investing world, and not only that!
Indeed, Munger dedicated his life to the discovery, development, and interiorization of a variety of heuristics (thinking tools), which he used to make business decisions throughout his life.
Munger's impact on Buffett's investment approach was significant, and their collaboration played a crucial role in the success of Berkshire Hathaway.
Despite Munger's preference to stay in the background and let Buffett be the face of Berkshire, his wisdom and participation were instrumental in building the company into an investment powerhouse.

The key insights from Charlie Munger are multiple, and they move along three lines of thoughts:
The Pursuit of Worldly Wisdom: Munger emphasized the importance of outsmarting rather than outworking others. He advocated for asking questions and using models to reveal and explain mistakes, viewing it as a puzzle to be solved.
Engagement in Rarely Used Skills: Munger believed in practicing useful, rarely used skills outside one’s discipline as a duty to one’s better self, which he considered essential for avoiding errors and the “man with a hammer” tendency.
Psychology of Human Misjudgment: Munger’s insights on psychological tendencies, such as inconsistency-avoidance, curiosity, envy, and social-proof tendencies, provided a framework for understanding human behavior and making better decisions.
His wisdom extended beyond investing, influencing countless individuals.
Munger's remarkable insights and teachings were a cornerstone of the annual Berkshire Hathaway meetings, attracting thousands of investors eager to learn from his wisdom.
Thus, Munger's legacy is not just about investing; it's about the enduring impact of his wisdom and wit, which will continue to inspire and guide investors for years to come.
Charlie Munger’s heuristics encompass a range of principles that guided his decision-making and contributed to his success. Some of these heuristics include:
Munger's study on Human Misjudgment
Early in his life, Munger figured out that human judgment was somehow influenced by a set of social cues, which he cataloged, studied, and learned from experience, in what he called Human Misjudgment, or a set of heuristics that drove his decision-making process, throughout his life!
These are:
Reward and Punishment Superresponse Tendency: Incentives and disincentives have a tremendous impact on human action. To persuade, appeal to interest, not to reason.
Liking/Loving Tendency: People tend to judge in favor of individuals and symbols they like. This tendency can lead to wrong decisions when individuals deliberately ignore or distort negative facts because they come from friends or admired sources.
Disliking/Hating Tendency: The opposite of the liking/loving tendency, this tendency leads individuals to ignore the positive qualities in a person or entity they dislike and hate all associated things. In investing, it's important not to let personal dislike influence decision-making.
Doubt-Avoidance Tendency: This is the inclination to make quick, poorly thought-out decisions under stress. The pressure to remove doubt can lead to ill-informed choices. To counter this, deliberate delays can be created when under pressure.
Inconsistency-Avoidance Tendency: Humans are creatures of habit, and their brains tend to conserve energy and space by avoiding inconsistency and being reluctant to change. In investing, it's important to keep an open mind to new facts to arrive at the best possible decision.
Curiosity Tendency: People have a natural inclination to seek more information, which can be beneficial for staying informed. However, overdoing it can complicate decision-making.
Kantian Fairness Tendency: This tendency relates to the desire for fairness and reciprocity in human interactions.
Envy/Jealousy Tendency: This tendency can lead to negative emotions and behaviors, affecting decision-making and relationships.
Reciprocation Tendency: People tend to reciprocate behaviors, both positive and negative. In investing, it's important to be cautious of potential ulterior motives behind certain behaviors.
Influence-from-Mere-Association Tendency: People often perceive things based on who or what they are associated with. Careful consideration is needed to avoid being misled by accidental, non-causative factors.
Simple, Pain-Avoiding Psychological Denial: This tendency involves avoiding facing painful truths, which can lead to poor decision-making.
Excessive Self-Regard Tendency: Overestimating one's abilities and knowledge can lead to arrogance and poor decision-making.
Overoptimism Tendency: Being overly optimistic can lead to underestimating risks and making poor decisions.
Deprival-Superreaction Tendency: People tend to react strongly to the feeling of deprivation, which can lead to irrational decision-making.
Social-Proof Tendency: People tend to follow the actions of others, even if it's not the best course of action.
Contrast-Misreaction Tendency: This tendency involves reacting strongly to contrasts, which can lead to distorted perceptions and decisions.
Stress-Influence Tendency: Under stress, individuals may make quick, poorly thought-out decisions, leading to ill-informed choices.
Availability-Misweighing Tendency: This tendency involves giving undue weight to information that is readily available, leading to biased decision-making.
Use-It-or-Lose-It Tendency: People tend to use skills and knowledge they have, or they lose them. This can lead to a reluctance to learn new things.
Drug-Misinfluence Tendency: The influence of drugs can lead to impaired judgment and decision-making.
Senescence-Misinfluence Tendency: As people age, their judgment and decision-making abilities may decline.
Authority-Misinfluence Tendency: People tend to be influenced by authority figures, even when it's not in their best interest.

Reason-Respecting Tendency: People tend to be influenced by reasoning, even when it's flawed.
Lollapalooza Tendency: This is the combination of multiple tendencies acting in the same direction, leading to extreme outcomes.
Let's get into each of them and their real-world applications!
Reward and Punishment Superresponse Tendency:
The "Reward and Punishment Superresponse Tendency" underscores the significant influence of incentives and disincentives on human behavior. It suggests that individuals are highly responsive to the prospect of gain or the fear of loss, sometimes to the detriment of logical reasoning. In practical terms, this means that people may be more motivated by financial rewards or penalties than by objective evidence or reasoned arguments.
Real-world Application: This tendency has critical implications for various fields, from business and finance to public policy. For instance, businesses often use financial incentives to motivate employees to meet performance targets. In investing, understanding how this tendency operates can help investors avoid making impulsive decisions based solely on the allure of potential profits or the fear of losing money.
Liking/Loving Tendency:
The "Liking/Loving Tendency" is rooted in the human inclination to judge in favor of individuals and symbols they have positive feelings toward. This bias can lead individuals to ignore or downplay negative information about people or things they like, potentially resulting in flawed decision-making.
Real-world Application: This tendency is frequently observed in everyday life. People may trust the advice or recommendations of friends or admired figures, even when those suggestions are not based on sound reasoning or evidence. In business and marketing, it underscores the value of building positive brand associations and customer loyalty.
Disliking/Hating Tendency:
Conversely, the "Disliking/Hating Tendency" leads individuals to ignore positive qualities in a person or entity they dislike or hate. This can result in a distorted and one-sided perception, potentially leading to irrational decision-making.
Real-world Application: In investing, it is crucial not to let personal biases and animosities influence financial decisions. For instance, disliking the management of a company should not cloud one's judgment when evaluating the company's investment potential objectively.
Doubt-Avoidance Tendency:
The "Doubt-Avoidance Tendency" refers to the tendency to make hasty, ill-informed decisions under stress or pressure. The desire to eliminate doubt can lead to impulsive choices, sometimes to the detriment of one's long-term interests.
Real-world Application: In high-stress situations, such as financial crises or emergency decision-making, this bias can lead to snap judgments that are not well-considered. Creating deliberate delays or utilizing structured decision-making processes can help counteract this tendency and lead to better outcomes.
Inconsistency-Avoidance Tendency:
Humans have a natural aversion to inconsistency and change. The "Inconsistency-Avoidance Tendency" explains our reluctance to alter established habits or beliefs, even when presented with new information that contradicts them.
Real-world Application: In the context of investing, this tendency can hinder adaptability and open-mindedness. To make sound investment decisions, it is essential to remain receptive to new facts and be willing to adjust one's strategies when warranted.

Excessive Self-Regard Tendency:

Real-world Application: Overconfidence can impact professional judgment and decision-making in various fields, from finance and entrepreneurship to healthcare and education.

The "Deprival-Superreaction Tendency" suggests that people react strongly to the feeling of deprivation, which can lead to irrational decision-making. Loss aversion, a related concept, is part of this tendency.

Real-world Application: Social proof is a powerful marketing tool, with companies often showcasing testimonials, user reviews, or social media engagement to influence consumer behavior.
Contrast-Misreaction Tendency:
The "Contrast-Misreaction Tendency" involves reacting strongly to contrasts, which can lead to distorted perceptions and decisions. People may overemphasize differences when comparing two or more items or situations.
