Indonesia's IQ Below Global Average? Analysis of International Test Results

According to data from the International IQ Test (IIT) conducted in 2025, Indonesia's average IQ was 89.96, significantly below the global average of 100. The study involved 1,352,763 participants worldwide, and their results were used to calculate the average IQ for each country. Indonesia was ranked 12th among countries with the lowest average IQ scores. This result may suggest potential challenges regarding the cognitive abilities of its population. IQ (Intelligence Quotient) is used as a standardized measure to compare an individual's cognitive abilities within a specific population group. Generally, the average IQ is set at 100, representing the average cognitive capacity of the reference group. The IIT data indicates that factors such as the education system, nutritional status, or other socioeconomic conditions in Indonesia might be influencing the average cognitive capacity of its citizens. However, it is important to note that IQ test scores alone cannot definitively determine the overall intellectual level or future potential of an entire nation. Source: Detik
