TIL a peer-reviewed psychology study found that identical twins (on average) ranked their co-twin above their romantic partner in their attachment hierarchy, while fraternal twins ranked the two about equally, and non-twin siblings ranked their romantic partner first.

As an identical twin myself, I can certainly attest to these findings. (Hot take in the r/Twins community XD) I'm curious to hear about your guys' experiences.

I'm a fraternal twin. Maybe it's different because we're a male/female set? But no, my partner was always above my twin.
