Genetic bases of mental illness -- a cure for stigma?

An increased emphasis on biological causes of mental illness has been viewed as having the potential to significantly reduce stigma. From this perspective, the current genetics revolution can be seen as a source of hope. However, some have argued that biological attributions could increase stigma, for example by making the ill person seem 'defective' or 'physically distinct' -- 'almost a different species'. In this paper, I use a multicomponent conceptualization of stigma as a guide in forming hypotheses about the likely impact of genetic attributions on the stigma of mental illness.
