Nishi Uggalle, the latest crowned champion of Channel 4’s Child Genius show, is believed to possess an IQ “higher than Einstein’s”. Impressive as it sounds for a 12-year-old winning a junior Mastermind programme, but does the comparison with the infamous physicist actually mean anything? And how seriously should we consider IQ (intelligence quotient) as a benchmark of a person’s intellectual capacity? The most notable issue is that nobody knows what Albert Einstein’s IQ was because he never took the test. It is presumed he would have an IQ score of over 160.
