Sir

I was astonished to see the terms 'schizophrenic' and 'split personality' being used interchangeably in a News & Views article on high-temperature superconductivity (Nature 450, 492–493; 2007).

Although the usefulness of the concept of 'schizophrenia' in mental health is contested, the consensus is that it does not have anything to do with a 'split personality' (whatever that is). Why, then, is Nature perpetuating this inaccurate and potentially offensive usage of 'schizophrenic'?
