Sure, and to whom does a childhood friend first attach?

> But early friendship bonds played an even bigger part than maternal relationships in the ways people navigated adult friendships and romantic partnerships, accounting for 4 percent of the variance in adults’ romantic partner- and best friend-specific attachment anxiety, and 10 to 11 percent in their partner- and best friend-specific avoidance.

Are those numbers r-squared figures? Seems like there's a lot more variance to be explained?

My first reaction was to refute this, but I think I've convinced myself this may be correct, assuming attachment styles are the right frame.

I've been painted with the Avoidant brush, and logically it makes sense, broken home, removed from mother, moved regularly changing schools once a year for 5 years.

However, my siblings are the opposite. We come from the same house, they didn't change schools as often as I did, which made me wonder how we could be so different.

But when looked through the lens of friendships forming the attachment style, it makes more sense. I changed schools more often than my siblings, and therefore had more friendship changes, and less ability for attachment.

We've known roughly this since The Nurture Assumption (1998). Where parents do have an impact is in being able to choose the social circles their children are immersed in.
