Study busts lefty myth

In a study led by Professor Mike Nicholls, director of the Brain and Cognition Lab in Flinders University’s School of Psychology, left-handed participants consistently performed worse than their right-handed peers in IQ tests.

“The evidence, based on our analyses of very large databases of handedness and other attributes in people across Australia, the UK and the US, doesn’t bear out that myth,” Nicholls said.

“Our study of members of the same family confirms that left-handed children will do worse than their right-handed siblings,” he said. Nicholls said handedness is tied to left or right asymmetries in the brain, or laterality — a major research focus of the Lab.
