There was a more authoritarian ethos in the past, as, for example, when I joined the public service 25 years ago. However, it has now largely disappeared. Perhaps that ethos at times discouraged questioning and discussion and, on occasion, created scope for untoward activities on the part of a small minority. I still occasionally see signs of it being an unhealthy attitude in some public bodies in terms of their reaction to genuinely motivated whistle-blowing. It is not limited to these bodies, but extends to commercial bodies also. I refer to the evidence uncovered by the DIRT inquiry.
