Politicians and public bodies do it all the time of course, but so do many ordinary individuals who hate to be caught out in any way.
I left my last job after my boss accused me of releasing confidential documents to a civil servant. I pointed out that the documents were already freely available on our website, but he wouldn't listen. He sent me a three-page email accusing me of not doing my job properly, not obeying instructions and so on.
If only he could have admitted I was right and he was wrong, there wouldn't have been any problem. But no, he had to insist I was the one who'd screwed up.
The famous neurosurgeon Henry Marsh admits that in his early days as a brain surgeon he was somewhat arrogant and self-satisfied and wouldn't admit he'd been at fault at all. It was only later on in his career that he admitted making mistakes or misjudgments, and his ex-patients appreciated his honesty.
My prostate operation apparently went very well, but if it hadn't and the surgeon had made some bad mistake, I would have expected him to be frank with me, and not cover up and pretend everything went fine (if he'd done so, I probably would have smelt a rat anyway).
What exactly is wrong with admitting mistakes? It's only by freely examining your mistakes that you learn lessons and become a better person. I'm happy to acknowledge my mistakes and whatever they might teach me.
