Sir Humphrey explains the role of a civil servant

It's instructive though, despite the flaws, and at this point has been replicated enough in different ways that we know it's got some basis in reality. There's a whole bunch of constructivist research around interactionism, that shows that whilst it's not just the person's default ways of behaving or just the situation that matters, the situational context definitely influences what people are likely to do in any given scenario. Reicher & Haslam's research around engaged followership gives a pretty good insight into why Zimbardo got the results he did, because he wasn't just observing what went on. That gets into all sorts of things around good study design, constructivist vs positivist analysis etc, but that's a whole different thing. I suspect, particularly with regards to different levels, there's an element of selection bias going on (if for no other reason that what we see in terms of levels of psychopathy in higher levels of management), but I'd guess (and it's a guess), that culture convincing people that achieving the KPI is the moral good is more of a factor. That gets into a whole separate thing around what happens in more cultlike corporations and the dynamics with the VC world (WeWork is an obvious example) as to why organisations can end up with workforces which will do things of questionable purpose, because the organisation has a visible a fearless leader who has to be pleased/obeyed etc (Musk, Jobs etc), or more insidiously, a valuable goal that must be pursue

Sir Humphrey explains the role of a civil servant [this video] "Bernard, I have served eleven governments in the past thirty years. If I had believed in all their policies, I would have been passionately committed to keeping out of the Common Market, and passionately committed to going into it. I would have been utterly convinced of the rightness of nationalising steel. And of denationalising it and renationalising it. On capital punishment, I'd have been a fervent retentionist and an ardent abolitionist. I would've been a Keynesian and a Friedmanite, a grammar school preserver and destroyer, a nationalisation freak and a privatisation maniac; but above all, I would have been a stark, staring, raving schizophrenic."
