Who is the smartest world leader today?

Determining the "smartest" world leader is subjective and depends on various metrics such as education, intellect, decision-making skills, and the ability to navigate complex global issues. Leaders like Angela Merkel, known for her scientific background and pragmatic approach, and Jacinda Ardern, recognized for her empathetic leadership during crises, are often highlighted for their intelligence. However, the effectiveness of a leader can also depend on context, collaboration, and the challenges they face, making it difficult to crown a single "smartest" leader.
