Emily's father has three daughters — name the third one
Emily's father has three daughters. The first is named April, the second is named May. What is the third daughter's name?
Reveal the answer
Emily. The question tells you her name in its very first sentence — but the pattern 'April, May, ...' primes an automatic, wrong answer ('June') that most people blurt out before rereading the sentence. It's one of four items on the CRT-2, a less math-heavy alternate version of the Cognitive Reflection Test built by psychologists Keela Thomson and Daniel Oppenheimer to catch the same snap-judgment-versus-reflection failure as the original bat-and-ball question, without requiring any arithmetic.
