Even though I agree with you, that's not a fact and, if a bunch of people are happy all being exactly the same, that's great for them. You can have any amount of ideas about how things should be but if someone is happy the way they are, that's what's important, that's the end goal.
I think the key difference- at least for the book I mentioned - is that it actually teaches to you take a genuine interest in those around you. It's not a mask or a ploy, it is making you engage positively in a way that yields genuine connections.
Example: if at the start of a conversation a personal anecdote comes to mind but you think 'no that's not what the book said, I should talk about the other person instead' I'd argue you're masking your natural persona. If your natural inclination is to raise an eyebrow but no that's not what I was taught smile instead, that's a mask. You see it often among high earning people and it's pretty transparent. Luckily you often also see people who are not at all like that everywhere and they're the ones I'll prefer having a drink with 10/10 times.
There are similar socialization rituals. When you are in karate you might be taught to bow before entering a dojo or sparring with a partner. Is that an inauthentic mask because you are conforming to the respect rituals? Or how about a military salute? These norms are part of the social lubrication that makes relationships easier to form. And the process of socializing a person is teaching them to incorporate them as authentic parts of themselves.
If you change your entire personality based on a self-help book.. that probably says a lot about your personality.
And anyway twin studies make the hardware seem more impactful than the software in many ways..
And twin studies, while persuasive that biology does have a massive impact are not dispositive compared to similar studies on human development theory that has longer population sizes that show self dialogue can shape behavior over time.
I don't think the word "inauthentic" quite captures why people react negatively to this sort of communication.
At least part of it comes from the fact that this particular style of "kindness-is-cool-coded" (for lack of a better word) communication happens to be the preferred style of insanely passive-aggressive people who take it upon themselves to brutally sabotage anyone who they deem unacceptable. It can also feel like you're being lead on by someone who actively dislikes you but is too polite to say it. Or you just start second-guessing every single thing they say and do.
But honestly, there's a pretty sizable minority of people who are repelled by this type of person and if you're naturally bad at reading the room you're probably better off making friends with other people that say and do dumb things.
I know I went through a "How to Win Friends and Influence People" phase when younger and basically ended up just putting off a whole of people.
Likely stems from a hundred and fifty odd years of the "always British" types swanning it over the "this is where we live and we love it" crowd.
Aside from being about forming sincere relationships, it handles influence with essentially this advice: Stop trying to force people to care about what you want. Understand what they want, treat them with respect, and align your request with their self-interest and self-image. If you come off as false doing those things, it’s because you didn’t actually do them, you pantomimed them.
“You’re such a generous person. I know you love being there for friends. Could you help me move Saturday?”
It's an example that of course sounds ridiculous to anybody that reads it, but it's essentially what the book teaches. Gather information not even about the person but how the person feels about themselves and then use that as a tool to make them feel good when you're talking to them.
I suppose it's also not helped that many of the people I've met who use this and admire this book have psychopathic traits. They're very good at faking caring but actually can't. It's a cold calculation to them and admittedly it's very effective at getting them ahead.
I don’t know how you could read that book in a modern frame and get syrupy insincerity out of it in good faith, but it is true that many people read this type of book looking for shortcuts and hacks, so they are not looking for the good faith reading. If you read the rest of NH’s work, you will find that his philosophy is firmly based on genuine good faith and delivering disproportionally high value to the people you interact with. (As well as some very 19th century metaphysics you can safely ignore)
But yes, many people read that book, ape the ideas, and act like asshats. It’s hardly a failing of the book.
Manipulation seeks to get someone to do what you want against their interests.
Persuasion seeks to align their interests with your interests in a mutually beneficial manner. The act of speaking to their interests by definition takes their well being into consideration.
And the book “the game” isn’t an example of that skill. People that follow those techniques find out quickly that they end up destroying the connections they make really quickly.
Note that The Game isn't a PUA manual, it's investigative journalism into the PUA scene.
This is the part that gets me to have an almost allergic reaction. It feels like an almost homogenization of people's personalities. In my mind I picture it like this: business man A reads How to Win Friends and Influence People. Businessman B also reads it. Business man A meets B and see that they're doing the psychological tricks of the book and think "wow this guy sure knows how to win friends and influence people like I do" so they get along fantastically.
It's similar to my aversion to books like "The Game" where some men seem to have the idea there's a surefire way to pick up women. Humans are diverse and should have differences in how they treat others and react. "Remember their name, smile, talk about the other person" and all the other tricks often gets me in the mindset of "this person is media trained / inauthentic".
