Dr Timimi raises the much larger issue of scientific racism in psychiatry in his letter. How much of this is institutional is difficult to determine but I contend that this is not the primary responsibility of journal editors to correct. The duty of an editor is to inform, to promulgate and explicate rather than to direct and legislate, and if this is done successfully it can help, together with many other influences, in changing minds and opinions. So we carry this out using the approach of Harriet Beecher Stowe rather than that of Abraham Lincoln and, if we change public opinion through the written word, we can also influence the climate of psychiatric practice favourably.

I hope that the Journal is helping to change opinion more in Dr Timimi's direction in the spirit of my editorial (Reference TyrerTyrer, 2005). So we accept that our definitions of psychiatric illness are indeed too centred on the developed world and point out, for example, that the ICD-10 and DSM-IV diagnostic classification descriptions of anorexia nervosa are deficient in Ghana as those with the condition there ‘would not be classed as having anorexia nervosa, as they had neither a morbid fear of fatness nor a pervasive need to be slim. Rather, they reported a desire to exert self-control through deliberate self-starvation’ (Reference Bennett, Sharpe and FreemanBennett et al, 2004). Similarly, in changing our attitudes towards British-Caribbean people who have schizophrenia, if we appreciate that stigma is likely to be a consequence of delayed presentation and compulsory admission (Reference Morgan, Mallett and HutchinsonMorgan et al, 2005), then we are able to both give an explanation and possibly gain from the experience of other countries in getting services provided early to a stigmatised group (Reference Chatterjee, Patel and ChatterjeeChatterjee et al, 2003). I therefore do not share Dr Timimi's pessimism; by opening up the debate we have moved from ‘powerful psychiatrists interpreting the existing evidence’ in their favour, to powerful evidence from around the world influencing the responses of all psychiatrists, irrespective of their status. Long may this process continue.
