Studies have shown that people who have a preference for using their right hand tend to have brains in which the left-hemisphere is dominant. Some scientists have suggested that for ambidextrous people, neither hemisphere in the brain is dominant. It is generally understood that there are four variations of handedness.

Is it bad to be naturally ambidextrous?

A study of 11-year-olds in England showed that those who are naturally ambidextrous are slightly more prone to academic difficulties than either left- or right-handers. Research in Sweden found ambidextrous children to be at a greater risk for developmental conditions such as attention-deficit hyperactivity disorder.

Is ambidextrous more intelligent?

The study found that left-handers and right-handers had similar IQ scores, but people who identify as ambidextrous had slightly lower scores, especially in arithmetic, memory and reasoning.
