Also, beware of taking generalities (such as the claims of this study) and applying that directly that to your specific life, or anyone else's.

I mean, I like your comment and am glad you got thinking about this, but it's just a line of reasoning that I see a lot and I wish I saw less, so that's why I bring it up (:

"True for most people" does not imply "true for me" or "true for that person over there".

And the reverse is not valid either, of course - "true for me" does not imply "true for most people."

There's always some tension between people's individual anecdotes and experiences (which are fascinating, and I like), and the claims of broader studies like this one.

Sometimes I try to remind myself of this with the "on average, people have 2.3 children" factoid. Obviously, nobody actually has 2.3 children; the general truth does not necessarily apply to specific individuals; potentially not even a single one.

100% agree. I actually think of attachment styles like this generally. Your upbringing does not dictate your life, it influences.
