The military is a terrible example. It is literally illegal to leave. If you leave during war, they can execute you. Boot camps are meant to deeply change how humans behave so that they can survive war, a deeply traumatic experience that often results in lasting psychological damage. When people apply boot camp models in civilian contexts, abuse is widespread:<p><a href="https:&#x2F;&#x2F;www.google.com&#x2F;search?q=boot+camp+abuse" rel="nofollow">https:&#x2F;&#x2F;www.google.com&#x2F;search?q=boot+camp+abuse</a><p>&gt; but I don&#x27;t know how much it matters for performance.<p>Sure, we can agree that you don&#x27;t know. Maybe you should try it and find out. But I&#x27;m saying that in my experience it has mattered a great deal, and as recently as yesterday.<p>You&#x27;re saying that you want people to be different, to learn to take harsh criticism and subtract the harshness. I prefer to work with people as they are, which is as human beings who are sensitive to harshness, people who have a much easier time listening to people that they trust than people who are assholes to them.<p>I&#x27;m not particularly good at it. I&#x27;m arrogant and self-centered enough that I&#x27;d rather just say what I want in a fashion that is convenient and emotionally satisfying <i>to me</i>. But if I am going to work with other people, I often have to choose between the thing that is easy for me and the thing that makes change easy for them. Even if I didn&#x27;t want people to generally do well and be happy (which I do), I just won&#x27;t get very far in having the real-world effects I want if other people are indifferent or hostile to me.
