Cognitive reflection test (Shane Frederick)

The Cognitive Reflection Test (CRT) is a psychological test developed by Shane Frederick to measure one's tendency for analytical thinking. It consists of three questions that require a quick and conscious thought process in order to be answered correctly. The correct answer for each question is not necessarily obvious and requires taking the time to think through the implications of each choice. This test is used to measure cognitive flexibility, the ability to think analytically and logically, and how well one can resist the initial impulse to go with the first answer that comes to mind.
