What Is a Decision Tree and How Can It Help You Survive?


Survival situations can be chaotic and overwhelming. When faced with critical decisions that could mean life or death, having a clear thought process is crucial. This is where a decision tree can come in handy. In this article, we will explore what a decision tree is, how it can be used, and how it can help you survive in various situations.

What Is a Decision Tree?

A decision tree is a graphical representation of a decision-making process that can help you analyze different possible outcomes and choose the best course of action. It consists of nodes, branches, and leaves, where nodes represent decisions, branches indicate different options, and leaves represent possible outcomes.

Creating a Decision Tree

To create a decision tree, start by identifying the main decision that needs to be made. This could be anything from deciding which route to take when navigating unfamiliar terrain to determining whether a water source is safe to drink from. Once the main decision is identified, break it down into smaller, more manageable decisions and consider the different options for each decision point.

For example, if the main decision is whether to stay put or continue moving, the smaller decisions could include factors such as available resources, weather conditions, and proximity to potential dangers. Each option for these smaller decisions is then represented by branches in the decision tree.

Using a Decision Tree for Survival Situations

Decision trees can be particularly useful in survival situations because they help you think through various scenarios and potential outcomes. By mapping out your options and considering the consequences of each decision, you can make more informed choices that increase your chances of survival.

Here are a few ways decision trees can be used in survival situations:

1. Navigating unfamiliar terrain: When exploring unknown territory, a decision tree can help you decide which path to take based on factors such as terrain, available resources, and potential hazards. By evaluating different options and the corresponding risks, you can make a more educated decision about which route is safest and most efficient.

2. Assessing water sources: Finding safe drinking water is crucial for survival. A decision tree can assist in determining whether a water source is safe to consume from. Consider factors such as proximity to potential contaminants, clarity of the water, and the availability of purification methods before making a decision.

3. Finding shelter: When seeking shelter in the wilderness, a decision tree can help you assess different options. Consider factors like the stability of the structure, proximity to potential dangers, and available resources. By evaluating these factors and mapping out the potential outcomes, you can choose the safest and most suitable shelter option.

Benefits of Using a Decision Tree

Using a decision tree in survival situations offers several benefits:

1. Structured decision-making: Decision trees provide a structured approach to decision-making by breaking down complex problems into smaller, more manageable components. This allows you to think through each decision point and consider all potential options and outcomes.

2. Visual representation: The graphical representation of decision trees makes complex decision-making processes easier to understand and follow. Visualizing the options and outcomes helps you grasp the situation more effectively, even in high-stress situations.

3. Increased likelihood of success: Making informed decisions increases your chances of success in survival situations. By evaluating the potential risks and rewards associated with each option, you can choose the course of action that maximizes your chances of survival.

4. Flexibility and adaptability: Decision trees are flexible and adaptable. As the situation evolves, you can revise and update the decision tree to reflect new information or changing circumstances. This allows you to make adjustments to your plan as needed, enhancing your chances of survival.


Survival situations require quick and critical decision-making. By utilizing a decision tree, you can organize your thoughts, evaluate options, and choose the best course of action based on the potential outcomes. Whether you are navigating through unfamiliar terrain, assessing water sources, or finding shelter, decision trees can be a valuable tool in increasing your chances of survival.

My 2 Cents

Decision making in survival situations can be overwhelming, but utilizing a decision tree can significantly enhance your decision-making process. Taking the time to map out your options, evaluate potential outcomes, and consider various factors can make all the difference when it comes to survival. Remember, practice using decision trees in non-survival situations to familiarize yourself with the process. Lastly, stay calm, think clearly, and make decisions based on the information available to you. Stay safe out there!
