You may have seen this test before. It's called the Cognitive Reflection Test, or  CRT. It was developed by psychologist who picked the following three questions because they were all “found to yield impulsive erroneous responses.” In other words, your initial "gut" response has a tendency to be wrong. Have a go!

  

1.  A bat and a ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?
2.  If it takes five machines 5 minutes to make five widgets, how long would it take 100 machines to make 100 widgets?
3.  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?
