The World's Shortest IQ Test Is On 3 Questions by Nobody: 11:51am On Dec 11, 2017 |
Taking an IQ test doesn't have to be akin to drilling through the marathon of questions that is the SAT. (Please don't make us go through that again. Please.) In fact, what has been hailed as the world's shortest IQ test in the world is a whole three questions. Yup, you can take it right now and start bragging to your friends within 30 minutes. 1. The Bat and Ball Problem A bat and a ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost? 2. The Widget-Making Machine Problem If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets? 3. The Size-Double Lily Pad Patch Problem There is a patch of lily pads in a lake. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half the lake? Trick Questions The Cognitive Reflection Test (CRT) was developed by psychologist Shane Frederick in 2005. In a paper published in The Journal of Economic Perspectives, Frederick describes that he picked the three questions for the CTR because they were all "found to yield impulsive erroneous responses." That is, the questions make it easy for people to quickly jump to conclusions, instead of closely analyzing the seemingly simple quiz items. This kind of mental trickery is how only 17 percent of students from the top universities in the world (like Yale and Harvard) got a perfect score on the CRT, according to a 2003 study. This short test was designed to test someone's ability to ignore their intuitive gut response and think more rationally. Scroll down to try out the questions, and keep scrolling to check your answers. Culled from Curiousity. 2 Likes |
