Pareto's Principle, also known as the 80/20 rule, was discovered by Italian economist Vilfredo Pareto. It is a power law distribution that states that approximately 80% of the effects come from 20% of the causes. Pareto analyzed income statistics and concluded that income distribution is stable and does not change over time. However, he acknowledged that Pareto's Principle does not apply to the low-income group. Today, Pareto's Principle is considered valid only locally for income distribution. Pareto's Principle was supported by the Italian Fascist Party as a theory justifying the rule of the majority by an elite minority. Pareto's Principle suggests that about 20% of the key people in an organization bring most of the benefits, and when that 20% of key people are culled, 20% of the remaining 80% will again bring most of the benefits. This principle is often applied to various examples beyond economics, such as natural phenomena and social phenomena.

Prospect theory is a decision-making model under uncertainty that describes how people make choices when the benefits or losses they will receive as a result of their choices and the probability of those benefits or losses are known. ¹ This theory is well known as a representative work in behavioral economics. Prospect theory is based on three main principles: 1. Loss aversion: People weigh losses more heavily than the same amount of gain. That is, losing $10,000 has a greater impact than gaining $10,000. 2. Diminishing sensitivity: As the absolute value of a gain or loss increases, the feeling of it becomes less noticeable. For example, if someone who already has $10,000 receives another $10,000, the pleasure they feel is less than the pleasure they felt when they first received $10,000. 3. Reference-point dependence: People evaluate gains and losses not in absolute terms, but as changes from a certain reference point (e.g., their current wealth). These principles help us understand h...

Chapter eleven of Sun Tzu's Art of War, "The Nine Situations", emphasizes the importance of strategy based on terrain. This chapter describes nine different types of terrain and the respective strategies for each. 1. Dispersive Ground: A place where you fight within your own territory. Here, you should avoid combat. 2. Facile Ground: A place where you have shallowly penetrated into enemy territory. Here, you should not stand still. 3. Contentious Ground: A place that is advantageous if captured by the ally and advantageous to the enemy if captured by them. 4. Open Ground: A place where both allies and enemies can move freely. 5. Intersecting Highways: A place where the territories of several leaders connect and become a key point of traffic. 6. Serious Ground: A place where you have deeply penetrated into enemy territory and have many enemy cities behind you. 7. Difficult Ground: A place where you cross mountains, forests, and marshes, and the march is difficult. 8. Hemme...

Chapter ten of Sun Tzu's "The Art of War", titled "Terrain", explains how to strategize based on the terrain of the battlefield. Specifically, it discusses the following six types of terrain: 1. Accessible Terrain: A place where both allies and enemies can easily arrive. Here, if you position your troops on a sunny hilltop before the enemy arrives and secure your supply lines, you can gain an advantage. 2. Entangling Terrain: It's easy to go, but difficult to return. Here, you can win if the enemy is unprepared, but if they are prepared, you can't win and it's also difficult to retreat, which is disadvantageous. 3. Indecisive Terrain: A place that is disadvantageous for both allies and enemies. Here, you should not advance in response to enemy provocation. It is advantageous to retreat your troops and attack when half of the enemy has passed the branching point and advanced. 4. Narrow Passes: The entrance is narrow and the path widens as you go furth...

The ninth chapter of Sun Tzu's "The Art of War", titled "The Army on the March", discusses the deployment of troops and the reconnaissance of enemy situations. These principles can be applied not only to the battlefield, but also to strategic thinking in business and everyday life. 1. Crossing mountains: Travel along the valley, occupy a position higher than the enemy, and do not attack from low ground to high ground. 2. Crossing rivers: Once you have crossed the river, always move away from it. If the enemy crosses the river to attack, do not counterattack while the enemy is still in the river. It is advantageous to let about half of the enemy cross before attacking. 3. Traversing marshes: Pass through as quickly as possible and do not linger. 4. Deploying on flat ground: Occupy a flat place with good footing, place the hills on your right rear, and deploy with the low ground in front and the high ground behind. Understanding and appropriately applying these pr...

The eighth chapter of Sun Tzu's "The Art of War" is titled "The Nine Situations" (Responding to Changing Circumstances). In this chapter, Sun Tzu explains how to adapt to nine different situations on the battlefield. He states that a general who understands the benefits of these nine situations is one who knows how to employ troops. Sun Tzu proposes the following nine situations: 1. Dispersive ground(unfavorable terrain): Do not camp. 2. Facile ground(terrain that is advantageous to both enemy and ourselves): Establish alliances with other states. 3. Contentious ground(terrain that is advantageous to the first occupier): Pass through quickly without stopping. 4. Open ground(terrain that is equally accessible to both enemy and ourselves): Formulate strategies for retreat. 5. Ground of intersecting highways(terrain where four states meet): Fight desperately to escape. 6. There are roads which must not be followed. 7. There are armies which must not be attacked. 8....

The seventh chapter of Sun Tzu’s “The Art of War”, titled “The Army on the March”, discusses the importance of arriving at the battlefield before the enemy to gain an advantage in warfare. Specifically, it talks about “battles for the initiative”. This refers to the struggle for dominance before the battle begins. This chapter discusses “points to note for gaining the initiative”. It mentions tactics such as “indirect direct strategy” and “wind, forest, fire, mountain, darkness, thunder”. The “indirect direct strategy” is a tactic where you appear to take a detour but arrive before the enemy. In other words, it refers to a strategy that turns a detour into a shortcut. “Wind, forest, fire, mountain, darkness, thunder” represents the versatile nature of an army. The army moves quickly like the wind, making it difficult for the enemy to respond. It can also be eerily quiet, attack fiercely like a raging fire, defend solidly like an immovable mountain, remain undetected like darkness, and ...

The sixth chapter of Sun Tzu's "The Art of War" is called "Illusion and Reality". In this chapter, victory in war is sought by exploiting the enemy's weaknesses. Specifically, it discusses methods to advance the war situation advantageously by striking at the enemy's vulnerabilities. 1. The army that is already on the battlefield and waiting for the arrival of the enemy army is at ease, but the army that arrives later on the battlefield and enters the battle without a break is tired. Therefore, the skilled in war takes the initiative and does not move at the pace of the opponent. 2. The ability to lure the enemy skillfully comes from showing benefits to bait them. The ability to keep the enemy away skillfully comes from showing things that would be a disadvantage to prevent them from coming. 3. If the enemy is resting and at ease, tire them out; if they are full, starve them; if they are stationary, move them. 4. Always rush to where the enemy goes, atta...
