Getting into Mensa involves taking a test with dozens of questions, but apparently, there’s an easier way to check if you have superior IQ.
The Cognitive Reflection Test is the world’s shortest IQ assessment and contains just three questions, which appear relatively simple at first glance.
Published in 2005 in the Journal of Economic Perspectives, the test has resurfaced online following US Secretary of State, Rex Tillerson’s challenge to Donald Trump to ‘compare IQ tests’ after reports he called the president ‘a moron’.
The rapid test would be an ideal option for two such busy men to settle their dispute as it contains just three questions.
However, the test is, in fact, a lot more tricky than it looks and the proof of a high intellect is realising this and working out the answers accordingly.
Scroll down to take the test and find out if you have above average intelligence.
THE COGNITIVE REFLECTION TEST
1. A bat and a ball cost £1.10 in total. The bat costs £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?
