A recent study shows that left handed people are more likely to have an IQ over 131! Left-handers are also better at using both hands at once, and that may partly explain why it’s more common for them to be proficient musicians or professional athletes. Left-handers may also be more creative problem solvers as because of a tendency towards more connectivity between brain hemispheres.
Except Olivia Manning was an author who died in 1980, and the girl who scored a 162 on the Mensa IQ test was a 13 year old Indian girl from London named Neha Ramu. It's great that they're spreading this, and its amazing that a person is that smart, but they really need to get the facts straight.
