One is at face value, in terms of what the article is saying: that the things people look for in dating are not the things that bring happiness in a relationship. There's probably a lot of wisdom in what's discussed — find happiness in yourself before you look for it in a mate, what's important aren't the things you see at first glance in a potential mate, and so forth.
Another way of interpreting all of this though, is that the researchers are extremely off in the way they're approaching these topics. For instance, are people really happy in a relationship if they tell a researcher they're happy in the relationship? Is saying in a research survey that you're happy the same thing as being happy? Is it the same as predicting divorce or relationship dissolution? How would you measure relationship happiness? Is that the same as relationship functioning? Does the difference matter?
I'm not sure I want to take sides in terms of how the research is interpreted — it might be a bit of both — but I couldn't help but wonder if we're all just completely missing the boat with relationships. How people approach online dating apps isn't necessarily how people approach dating in general, and how people talk about their relationships with strangers isn't how they actually feel about them. Maybe the problems are with how online dating apps are structured?
I guess I came away from this really unsure of what to make of it. It's pitched as a message about how you should think about relationships, but I came away wondering about the dating research industry. For me it's a bit broader — I've started to wonder about reported well-being in surveys, for example, as barometers of actual societal well-being — but it applies to relationships nonetheless.
