The toddler, from Guildford in Surrey, is already bilingual, speaking both English and Russian, where her parents hail from, the Daily Mail reported.
She scored 162 on the Stanford Binet test an IQ quiz that looks to measure five factors of cognitive ability fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing, and working memory.
Alices advanced intellect means she is one of the top one per cent, matching that of Hawking, who has never officially revealed his IQ, but which is estimated to be between 160 and 165.
She already spends her spare time reading Aesops fables and other fairytales, also enjoying singing, dancing, painting, crafts and reading. We are delighted that Alice has joined the society, CEO of British Mensa, John Stevenage, said. Alice was admitted to Mensa after her parents submitted a report by British psychologist Professor Joan Freeman.
Her IQ of 162 ranks her higher than a list of the worlds greatest luminaries like former US presidents Abraham Lincoln and Benjamin Franklin.
