No, one study doesn’t upend the last few decades of understanding of emotional attachment.
The study simply says that ability to connect w friends is more predictive than observations they made of apparent attachment of parents.
This happens much later so of course it’s more predictive of the actual end effects - that’s when attachment styles actually show up for the first time. Kids grow up to be very adaptive toward their parents but when they get to the rest of society that’s when the failures of connection and the failed bids for attention show up.
A very resilient kid will do fine with friends even with a very bad attachment environment. A very sensitive kid or one with developmental problems will struggle in social environments.
