Why is it important to make decisions or draw conclusions based on sound, logical and valid reasons/ arguments

Because valid, logical, and valid reasons / arguments allow us to see things clearly and make rational decisions. With this, the chances of making wrong decisions are small.

Explanation:

It is from objective thoughts that the rational side of each is constituted. For this reason, using reason to choose between two options that need to be weighed is a wise choice. Being rational means using the ability to consciously grasp the meaning of things, applying logic to defining and understanding facts. Reason is one of the best resources to analyze the pros and cons of a situation because it considers the actual data.
