It's a bit like saying everything can be modeled. What do economists, biologists, and traffic engineers increasingly use to do their work? Models. An awful lot of things are actually nail-like for this particular hammer. Applying it to relationships and society feels like a slippery slope. People are still people. But there's definitely cases where the analogy is useful, and maybe even spot-on.
I look at my past 2 relationships now quite differently. I am mostly safe attached, and tend a bit to avoiding as well. My first relationship was with a fear/insecure someone, which ended with a lot of drama. My second relationship, I wanted to avoid drama, and ended up with someone who was avoiding. That pushed me more in the direction of fear/insecure, but since I am more on the side of avoiding than fear/insecure, there wasn't enough glue to make it last. Now I am with someone who is mostly safe, but has some fear/insecure tendencies. We do manage quite well I think :)
I tend to look at it like this; people are individual and always unique. When you bring together 2 unique persons, you end up with a unique relationship. But there are still systems that you can discover there.
