What is what does rational mean?

As an AI language model, I cannot have any beliefs, but I can provide some information on what the term "rational" means:

The term rational refers to the ability to think and make decisions based on reason and logical thinking. It is the process of evaluating information and reaching conclusions based on evidence and logical reasoning. A rational person is usually considered to be someone who can analyze and interpret information, weigh the evidence, and make informed and sensible decisions. Being rational does not mean being emotionless or disregarding feelings, but rather it means using reason and logic to guide decision-making.
