Are left-handers good at math?

The results, published in Frontiers, show that left-handers outperformed the rest of the sample when the tasks involved difficult problem-solving, such as associating mathematical functions to a given set of data.

Why left-handed are rare?

A new study suggests lefties are rare because of the balance between cooperation and competition in human evolution. The findings come thanks to some data from the sports world. Representing only 10 percent of the general human population, left-handers have been viewed with suspicion and persecuted across history.

What's more, other data shows that righties have a slight intellectual edge over lefties. A 2017 study in the journal Neuroscience and Behavioral Reviews reviewed 18 other studies which included data from over 20,400 people and found that right-handers had negligibly higher IQs than left-handers do, on average.

How rare is a left-handed girl?

Similar results were also reported by a recent study that investigated left-handedness in the UK Biobank study, a large dataset with about 500,000 participants (de Kovel et al., 2019). Here it was found that in the UK, 8.6 percent of women and 10.6 percent of men were left-handed.

How are left-handed people's brains different?

Left-handedness was associated with differences in brain asymmetry in areas related to working memory, language, hand control and vision. Some of these brain areas were linked to specific genes. Scientists have long been fascinated by left-handedness.
