Should the smartest country be defined by the highest literacy rate among its people? Or perhaps it would be the country with the highest average IQ? Another option might be to look at countries with a high percentage of exceptionally intelligent individuals or those whose citizens have earned the most Nobel Prizes. Some may even suggest using standardised test scores to rank intelligence—though creating a single test that could accurately assess intelligence across all cultures, languages, and educational backgrounds would be nearly impossible.

Any attempt to find a single answer has its obstacles. Yet, experts in population studies and intelligence continue to work on new methods that bring them closer to a reliable ranking of the world’s smartest countries.

One well-known study comes from British psychologist Richard Lynn. In his 2019 study, The Intelligence of Nations, Lynn and his colleague David Becker examined the average IQ of people from 132 countries and estimated scores for 71 others.

This article explores the leading countries based on these parameters, supported by statistics and relevant examples that highlight why these nations stand out in global intellectual rankings.

Defining “smartness” in national terms

While individual intelligence is often measured through IQ tests or educational achievements, evaluating the intelligence of a country encompasses broader aspects. Metrics often include:

• Education: Literacy rates, academic achievements, and percentage of the population with higher education.
• Innovation: Number of patents filed, contributions to science and technology, and research and development (R&D) spending.
• Technology: Advancements in artificial intelligence, biotechnology, and digital transformations.
• Cognitive abilities: Standardised test scores, such as PISA (Programme for International Student Assessment) scores.
• Quality of life: Access to quality healthcare, economic stability, and investment in public services.
