Impostor syndrom happens not because somebody was "primed", but because one knows one's own limits of competency and internal doubts better than anyone, but of course in others such things are not noticeable, so comparing oneself to others causes the person to self-doubt since everybody seems to be lacking internal struggles, deficiencies and doubts that are so clearly obvious to self.

Of course, various "positive discrimination" programs won't help this too, since once one belongs to a group which such a program targets, one has yet another - in this case, externally validated - cause to doubt if one's achievements are of one's own merit or were just bestowed by somebody else due to the fact of belonging to the targeted identity group. In this case, if the identity group is gender- or race-specific, of course this component is very prominent.
