Medicine and psychiatry often seem to be at the center of these regimes. Is there sometihng about doctors and ideology that goes so closely together? Maybe it's the pretext the regimes to suspend rules and rationality. German doctors began a "euthenasia" program several years before the war broke out, and no governing body of theirs seems to have historically been above using prisoners for medical experiments. Even r…
I don't feel there is anything "fundamentally wrong with many of them", but the role medicine plays in our lives makes it susceptible to exploitation by both messianic and psychopathic personalities. As a counter-example of medicine going hand-in-hand with despotism, there's Stalin's Doctors Plot, though there was a a lot of antisemitism there as well.
Changing individuals while doing only things to the individual, not touching the problems their behaviour is trying to solve. Pointing out that only a house solves homelessness, there's nothing a therapist can do. And research points out that therapists are destructive rather than helpful as soon as they go further than giving information or providing practical help.
So psychology/criminology/orthopedagogy/sociology is a fraud. The basic promise of these sciences is simple: that they can, through talking and "interventions" change the behaviour of unwilling humans (especially children). Time and time again research shows: they can't. It just doesn't work. They can cause extreme trauma, using some combination of violence, isolation and 24/7 stress, which results in specific behaviour patterns that can be summarised as long-term fear and extreme aggression, which, to put it mildly, isn't a recipe for a successful fulfilling life. Aggression by the psychologists is usually masked, by pretending locking up kids, or forcing isolation up to and including the use of isolation cells, "isn't violence".
Currently, the popular technique is called "applied behaviour analysis". Lock up kids, in isolation (no contact allowed), and cause 24/7 stress. But variants have many names: "New authority". "Non-violent resistance". "Rock and water". All have essentially been exposed as not changing behaviour, "not sticking", and the like. Not that practitioners actually follow these techniques particularly well.
