President Trump recently challenged Rex Tillerson, the US Secretary of State, to “compare IQ tests.”
Consequently, the Cognitive Reflection Test—dubbed the “shortest” IQ assessment in the world—has resurfaced on the internet, allowing netizens to have in on the feud between the two brains.
The three-question test might look straightforward, but it’s not quite what it seems. First published in 2005 in The Journal of Economic Perspectives, it analyzes a person’s tendency to overcome a gut response and observes the participant’s ability to further reflect on the questions.
Check out the questions and answers below. For more detailed solutions, head over to the Daily Mail.
1. A bat and a ball cost US$1.10 in total. The bat costs US$1.00 more than the ball. How much does the ball cost?
2. If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?
3. In a lake, there is a patch of lily pads. 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 of the lake?
