I've always been very, very distrustful of persuasion. The way the word is typically used, it means trying to convince someone using emotional means and other ploys, rather than advancing the empirical case. The reason I distrust it is that I grew up in an environment in which I didn't know who to believe. Also, given relatedness to people with mental illnesses, which I slowly realized was a fact, I was deathly afraid of being crazy. That was a real-life education in filtering out persuasion and other guff, and going straight for what counts if you want to know what's happening. It also taught me that often I simply will not know, and convincing myself it's A, or B, or C, is ill-advised if I don't know. Often in life the best answer is: "I do not have enough data. I could guess, but it would be a guess, and I have to remember that. If I get sloppy and start forgetting where I guessed, that's bad gambling, and the house will definitely win over time."
So, do unto others, I don't persuade others. Or as little as possible. I give people the information I think they might need, and I let them decide.
This is a handicap. I know. But sometimes there's a strength in taking on a handicap. So far, I'm not dead, homeless, friendless, or entirely unhappy, so maybe it's working ok.
But it all leads to a much bigger question. Because I'm interested in both human and animal psychology, I've become aware of many quirks in our nature that seem pretty weird and could be exploited. I'm not the kind of person who feels ok about exploitation. In fact, I'm sensitive enough to it that normal persuasion strikes me as exploitative. When people persuade me, I know what they're doing. It's almost like they're yelling at me what they're doing. I'm very aware of their tactics. If I'm convinced, it's because I like the person and wanted an opportunity to be pushed into what they're pushing for; in other words, persuasion can work on me when it's encouragement, but not when it's trying to make up for a weak argument. You can persuade me to go and see a movie when I didn't feel like it (because I generally value movies and time with friends), but not to view a poorly-substantiated position as well-substantiated. People's efforts to persuade in place of giving good arguments will often lead those people in those moments to call me stubborn, but that's because they're using the wrong tool for the job, not because I'm being stubborn.
I'm very careful in how I curate what I believe, and that you're my friend is irrelevant there.
But all of us are social creatures, and usually we aren't dealing in STEM-style proof in everyday life (though there are many situations where that is or would be an improvement, as science is incredibly useful, even in places where people have historically believed it isn't applicable). The funny thing about the word "manipulate" is that it has a negative connotation, yet everyone's constantly manipulating. I'm manipulating my keyboard. You might be considering manipulating me by responding to this post. When you say "Hello," it's a manipulation of the air and ears that often leads to a "Hello" or similar back. Our understanding of human nature and each other improves our manipulations; we interact better.
When I teach, I cannot avoid considering things like the effect of my emotional tone, or the damage I could do by saying additional true things that would only confuse right now.
So I'm often asking myself what knowledge is fair game to use, and what isn't.
For example, if I know that you like coffee, then I might consider giving you a coffee-themed gift over the holidays. That is a positive manipulation/exploit/tactic, because the idea is to get you something you'll actually enjoy. (Whether it's a successful gift or too simple a guess, we'll put to one side.) Sure, if the gift works out, the giving might go along with you appreciating me more overall, but that's always a possibility when we interact positively with others. Nothing really wrong with that. (Some would disagree with the latter, and say a gift should be entirely and scrupulously selfless in every way, but I think that's unrealistic and shows a lack of understanding of the motivation subsystem in brain tissue. No matter how selfless an act, in the end, the person acted that way because they valued it, and found the idea satisfying in some way, which meant they somehow felt good about it, or thought they might.)
For another example, I read about some research showing that if you are going to do someone a favor, they may actually appreciate it more if you don't hide that you aren't super thrilled about it. Favors can actually lead to resentment (we don't like feeling we owe someone), or else to people taking you for granted. But if you are open about the fact this is a hassle, or time-consuming, or effortful, or really not what you were planning to do, etc, and you do it anyway, the atmosphere kind of shifts to the person simply appreciating that you went out of your way for them. They take it less for granted, and they're less likely to feel a weird resentment about owing you, since you gave them a slightly hard time about it. Since reading that, this is a trick I use regularly. Not always; it's an option. If people know me well enough, I've mentioned the article, and presumably they know that I'm "manipulating" them or "exploiting" human psychology in this way. So in this case, I've decided that something potentially debatable falls on the side of "really ok and within anyone's rights to use." That's because the result seemed to be better relationships between people, people feeling more appreciated, less resentment, etc.
There are many other quirks and tricks like this I'm aware of but don't use. Many of them are evidently things people do use, because I see it. And it isn't wrong that they do. Not necessarily. My self-standard is not my other-standard. And I think that's an important distinction to make, for a variety of reasons. When we're good at something, for example, we typically raise our standard; that doesn't mean we should harshly judge the people who are average or decidedly untalented at it. When I misspell a word, I feel stupid, but that's because I'm good at spelling; when you misspell a word, I don't think you're stupid, I just think you aren't that good at spelling. In my opinion, this is exactly how self-standard versus other-standard should work. But that would be my opinion, given it's how I try to go about it, wouldn't it?
The emotional, relational subtext of all the above, beyond just some concepts and sharing something I've thought about a lot - in other words my unconscious motive behind speaking in the first place - is almost certainly along the lines of, "You may think I'm socially incompetent and bad at persuasion, but there's something you don't know: it's a conscious, effortful choice, one based on hard experience, and what I consider to be a higher standard in some ways, though I'm not judgy about this."
In the end, most of us want to be understood and appreciated, so it's pretty safe to assume that's the motive behind most of what people share. Some people are more skillful at disguising this, or convincing themselves they really don't care how they're evaluated, but that's mostly a ruse. Motivation is primitive, and the engine is quite similar for all of us.
My own motives aside, I hope you have a feeling of some small new insight.
