Reasoning vs Decision Making.
This is the best definition i've written so i'm keeping it here.
Think of reasoning like solving a puzzle. It's when you think carefully about all the pieces of information you have and try to figure out how they fit together. You ask yourself, "Does this make sense?" or "What does this mean?" Reasoning helps you understand things better.
Decision-making is like picking which tool you want to use. After you think things through with reasoning, you choose the best option based on what you learned. So, reasoning is about thinking, and decision-making is about choosing.
