Left and right, a battle for the truth

Bad BBC News! Bad! Bad! The idea that the left hemisphere of the brain is solely responsible for language functions is wrong. The idea that the brains of all left-handers are functionally reversed is wrong. The idea that left-handers are likely to die younger or are more susceptible to disease is also wrong. The BBC news site manages to make two of these mistakes in reporting research from Nature Neuroscience.

The first two of these popular ideas, as ever, have a kernal of truth but are considerable simplifications of a complicated picture. The last idea is just plain wrong. If you don’t believe me then read Chris McManus’ excellent ‘Right Hand, Left Hand‘.
