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.
