A no-blame culture has been widely [ quantify ] considered as a means to increase safety , in particular in areas where the consideration of possible human error is important, for instance in hospitals and in aviation.

The first configuration is what I came to call the Vampires’ Castle. The Vampires’ Castle specialises in propagating guilt. It is driven by a priest’s desire to excommunicate and condemn, an academic-pedant’s desire to be the first to be seen to spot a mistake, and a hipster’s desire to be one of the in-crowd. The danger in attacking the Vampires’ Castle is that it can look as if – and it will do everything it can to reinforce this thought – that one is also attacking the struggles against racism, sexism, heterosexism. But, far from being the only legitimate expression of such struggles, the Vampires’ Castle is best understood as a bourgeois-liberal perversion and appropriation of the energy of these movements. The Vampires’ Castle was born the moment when the struggle not to be defined by identitarian categories became the quest to have ‘identities’ recognised by a bourgeois big Other.
