Explaining Preference for the Left Hand

There are an estimated 13% of individuals who are left handed in the world. Although this number does not say much about the actual individuals who have a preference for their left hand, it does show that scientific research is needed in order to determine the causes of such a preference and the effects that being left handed may have. Here one can read more about the scientific explanation in what regards left handers and their ability to perceive the world differently.

There is no obvious reason why people choose to use one hand over the other when performing delicate tasks. Specialists have proven that many of the well known left handed facts are not as true as some people would have thought and as a result the cause for left handedness is still largely unknown. Specialists believe that there is a connection with genetics after observing families with left handed members. Yet, they are still uncertain to what extent the gene that is thought to be responsible for determining the preference for the left hand is the sole factor to play a role in this issue.

At the same time, specialists observed that some people are not born left handed but they develop the preference for the left hand as they grow up. This might be the result of the influence of a left hander in the family. Also, left handedness may be the result of an accident. If one can no longer use their right hand as a result of a serious injury they will learn to use their left one.

Bottom line, there is no exact cause that may lead to the preference of a hand over the other. However, as everything happens in the brain, scientists came up with the idea that the left handers have their right side of the brain as their dominant one, and not the left one. The right brain dominance in turn determines the likelihood that the left handers are more creative.
