🤔 Are IQ Tests a Fair Measure of Intelligence?
IQ tests measure certain types of cognitive ability, particularly logical reasoning, pattern recognition, spatial ability, and problem-solving. However, critics argue that IQ:
- Doesn’t capture creativity or emotional intelligence
- Can be influenced by socioeconomic background
- May be culturally biased
Despite these limitations, IQ is still widely used in psychology and education as a benchmark. It’s especially useful in large-scale population studies and longitudinal trends across nations.
🧪 Methodology: How We Collected This Data
IQ data in this tool comes from a mixture of peer-reviewed research (such as the work of Lynn & Meisenberg), educational achievement metrics, and global studies like PISA and TIMSS. We normalize scores to ensure comparability across different scales and years.
Please note: these figures are estimates. National averages can’t reflect the full diversity of individual intelligence or cognitive potential within any country.
