Although Suman Fernando has recently and eloquently documented institutional racism in psychiatry and clinical psychology, this has been from the perspective of contemporary Black history. This chapter looks at another form of racism – anti-semitism, particularly invisible anti-semitism. I will look first at definitions of anti-semitism, and the question whether it is on the increase. Turning to psychology I will offer some experiences from my life in psychology, and from the experiences of others, including experiences in universities in general, and some evidence from the history of psychology. Both visible and invisible anti-semitism will be described. One central issue is the ‘invisibility’ of Jewishness, the difficulty of identifying Jews as such, and the consequences of this, including the wish of many Jews for their Jewishness to be invisible.
