Years ago, I read The 48 Rules of Power. My brothers got it for me as a Christmas gift, since I like to write stories about powerful people, and they figured this would provide advice for stories about successful assholes. That was certainly the case.
Some of he major rules are to be dishonest in selective ways. Even the appearance of honesty is to be used in a selective fashion.
There are similar books about this, mainly dealing with improving your love life.
But what interested me is the people who take this seriously in their professional lives, especially if they’re operating in the public sphere. How do you deal with ambitious people who are really skilled at lying, and see it as virtuous? Scott Adams made a case that this was one of Trump’s great abilities, that he was willing to bend the truth in ways that go beyond standard politicians. Even if it failed him (which is debatable as he’s the frontrunner for the Republican presidential nomination in 2024) there may soon be people who are better at it. Some will be on your side politically.
