Key Differences

Logical thinking strictly adheres to formal rules of reasoning and is often associated with mathematical or structured problem solving. On the other hand, rational thinking takes a broader perspective, incorporating both logic and other factors like emotions, ethics, and practicality to make decisions.
Logical reasoning is objective, focusing on the correctness of arguments regardless of their real-world application, whereas rational thinking evaluates the outcomes and their alignment with goals or values.
Logical processes are primarily concerned with the form of arguments, ensuring they are valid and sound based on premises, while rational thought is more concerned with the effectiveness and appropriateness of decisions in specific situations.
Logical thought does not necessarily account for human behavior or subjective experience, whereas rational thought often involves considering these elements to achieve the most beneficial outcomes.
