Brain organisation

• No-one has come up with a definitive reason for WHY some people are left-handed, but about 13% of the population around the world are, and it is thought to be genetic - it definitely runs in families. Researchers have recently located a gene they believe "makes it possible to have a left-handed child " so if you have that gene, one or more of your children may be left-handed, whereas without it, you will only have right-handers - sorry! The good news is, that if you are left-handed yourself, you have that gene and will pass it on through the generations!

• The way the brain works is incredibly complex, but this simplified explanation will give you some understanding of where our left-hand dominance comes from. The brain is "cross-wired" so that the left hemisphere controls the right handed side of the body and vice-versa and hand dominance is connected with brain dominance on the opposite side - which is why we say that only left-handers are in their right minds!

• Things left-handers find tricky

• Us lefties find all sorts of daily tasks a bit more difficult just because of the way things are designed and laid out.

• Telephone boxes can be a challenge if you want to hold the phone with your right hand and write a note left-handed - often the cord is not long enough and off course the note table is on the right.

• London Underground (Tube) stations have automated ticket machine that are, of course, on the right as you enter. You can often see left-handers putting their ticket in the wrong slot (so the gates of the next entry point open instead) or fumbling to cross their hand over their body to get it in the right machine.

• There are many more examples like this. Have a look at our "Is it Me" page to find out more or tell us about problems you have found.

• The left hemisphere (RIGHT HAND CONTROL) controls Speech, Language, Writing, Logic, Mathematics, Science, this is the LINEAR THINKING MODE.

• The right hemisphere (LEFT HAND CONTROL) controls Music, Art, Creativity, Perception, Emotions, Genius, this is the HOLISTIC THINKING MODE

• Effects of right brain dominance •

This brain dominance makes left-handers more likely than right handers to be creative and visual thinkers. This is supported by higher percentages of left-handers than normal in certain jobs and professions - music and the arts, media in general. (See the results of our Lifestyle Survey of Left-Handers for our detailed findings) Left-handers are also generally better at 3-dimensional perception and thinking, leading, for example, to more left-handed architects than normal. Left-handers are also usually pretty good at most ball sports and things involving hand-to-eye co-ordination.

Effects of right brain dominance

The view that left-handers are clumsy and awkward is not down to their natural abilities, but being forced to use right-handed tools and machinery which is completely back-to-front for them.
