Important note: National average IQ scores are estimates based on limited sample sizes and vary across studies. These figures are heavily influenced by socioeconomic factors, access to quality education, healthcare, nutrition, and testing conditions. They do not reflect the intelligence or potential of any individual from that country. IQ scores measure specific cognitive skills and should be interpreted within their proper scientific context.
Where These Numbers Come From — and Why They're Debated
There is no official global IQ census. National IQ figures like the one above come from compiled cross-national datasets — most famously the compilations begun by Richard Lynn and Tatu Vanhanen (IQ and the Wealth of Nations, 2002) and successor datasets, alongside alternative estimates derived from international student assessments such as PISA and TIMSS. These compilations are heavily debated in the academic literature: critics have documented small and unrepresentative samples for many countries, scores extrapolated from neighboring nations, mixing of different tests and decades, and translation and cultural-fit problems. Different datasets can shift a country's estimate — and its rank — by several points.
For these reasons, the figure for Costa Rica should be read as a rough estimate of average performance on Western-style cognitive tests under the conditions in which the underlying samples were collected — not as a measure of the innate ability or potential of Costa Rica's people. Population-level test averages track education access, childhood nutrition, health, and economic development, and they change as those conditions change (see the Flynn Effect below).
Education System in Costa Rica
Costa Rica is exceptional in Central America for having abolished its military in 1948 and redirected spending to education and healthcare. The country has one of the region's highest literacy rates (97%) and most consistent education systems. Costa Rica was the first Latin American country to participate in PISA and has scored above the Latin American average. The country provides 12 years of free public education and invests around 7-8% of GDP in education. Challenges include urban-rural quality disparities and teacher strikes, but overall Costa Rica consistently outperforms its Central American neighbors in educational outcomes.

Understanding IQ Distribution
It's crucial to remember that national averages represent the middle of a wide distribution. Within every country, individual IQ scores span the full range from below 70 to above 130 and beyond. A country with an average IQ of 89 will have many individuals scoring well above and below that number. Factors like socioeconomic status, nutrition, education quality, and access to healthcare play significant roles in cognitive development and test performance.
The Flynn Effect — the observation that IQ scores have risen substantially over time in many countries — suggests that environmental improvements like better nutrition, healthcare, and education access can significantly impact cognitive test performance at the population level. Many developing nations are experiencing rapid improvements in these areas.
Frequently Asked Questions
What is the average IQ in Costa Rica?
Costa Rica's average IQ is estimated at 89, ranking #122 globally. Costa Rica is Central America's education leader, with 97% literacy and consistent investment following its 1948 abolition of the military.
Why does Costa Rica score 89 on average IQ?
Costa Rica's relatively strong score reflects seven decades of prioritizing education since abolishing the military in 1948, 7-8% of GDP investment in education, near-universal literacy at 97%, 12 years of free public schooling, and the political stability that allows long-term educational planning. The country's consistent outperformance of regional peers reflects sustained institutional commitment to human capital development.
How does Costa Rica compare to Panama?
Costa Rica (89) scores similarly to Panama (84). Both are Central American nations with relatively stronger education systems than their northern neighbors. Costa Rica has a longer tradition of education investment since abolishing its military, while Panama's greater per-capita income from the Canal Zone has funded education differently, with both countries achieving above-regional-average outcomes.
