<\/span>What Is the 3-Question IQ Test?<\/span><\/h2>\n\n\n\n

Definition and Origin<\/h3>\n\n\n\n

The so-called 3-question IQ test<\/em> is not actually a full IQ test. It\u2019s a condensed version of the Cognitive Reflection Test (CRT), a short assessment developed by behavioral economist Shane Frederick in 2005.<\/p>\n\n\n\n

Frederick designed the CRT to measure a person\u2019s tendency to override an initial, incorrect “gut” response and engage in further reflection to find the correct answer. It\u2019s not about how smart you are in the traditional IQ sense, it\u2019s about how you think.<\/p>\n\n\n\n
