Rational thinking is a process of using logic and reason to make decisions, solve problems or come up with solutions. It involves gathering relevant information, analyzing it objectively, considering multiple perspectives, and making conclusions based on evidence rather than emotions or personal biases. Rational thinkers are able to weigh the pros and cons of a situation, identify potential outcomes, and make informed decisions that take into account all available data. This type of thinking is considered essential for critical reasoning, effective problem-solving, and sound decision making.
