The Lensa IQ Test is a high-range IQ assessment granting a maximum score of up to 172. Under the pressure of a 30-minute time limit, you are given an array of 30 questions spread across spatial-visual, numerical and logical reasoning.
Test items include pattern recognition, series identification of numbers & letters, progressions & patterns within matrix-based representations, non-verbal & abstract deduction, and basic arithmetic.
Only your first and second scores are considered to be accurate.
IQ compared by countries
The question of the intelligence of a certain nationality or population may be controversial. In fact, intelligence is influenced by national, political, and geographic factors. Often surprisingly, but scientifically proven, a warmer climate has a markedly bad influence on the intelligence quotient. The average IQ scores for many populations have been rising at an average rate of three points per decade since the early 20th century, a phenomenon called the Flynn effect. It is disputed whether these changes in scores reflect real changes in intellectual abilities, or merely methodological problems with past or present testing.
