Neha Ramu, a 13-year-old from Surbiton, has been admitted to Mensa, after scoring 162 in the society's IQ test - putting her in the top 1% of people in the UK, and officially giving her the title of genius.
So what kind of company is she in, and does a high IQ guarantee a high-earning career?
The Telegraph reported that Ramu surprised her parents by getting the highest possible score for someone under the age of 18 on the test, which gives her a higher IQ than Albert Einstein, Bill Gates and Stephen Hawking (all of whom are thought to have an IQ of 160).
Entry to Mensa requires candidates to be among the top 2% most intelligent people in the world. It's a worldwide organisation, which provides a learning forum for its members, and is designed to help geniuses come together.
But does it guarantee success?
Clearly a high IQ is a tremendous starting point in life. Studies have revealed that IQ strongly correlates to income, and that a high IQ increases the likelihood of excelling in a variety of different areas because of the way information can be stored and processed.
However, wealth is not guaranteed. Those who choose a life of academia are unlikely to be richly financially rewarded.
Many of the most financially successful Mensa members are known for things other than their intellect. Geena Davis, star of The Long Kiss Goodnight is a Mensa member, as is Sharon Stone and Shakira. Quentin Tarrantino is also a member, despite the fact he dropped out of high school.
There are also plenty of low-achieving geniuses. IQ isn't a measure of what we know, how dedicated we are, how ambitious we are, or how hard we work: it's a measure of what we are capable of learning.
According to the BBC, Ramu is not going to be one of them. She wants to study neurology at Harvard University, and added: "If I don't put in my effort and make use of my IQ then there's no point in having it."
