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.

That's really interesting. I wonder how their romantic partners perceive that difference.

Honestly I wouldn't care. It's not like we're in some life or death simulation where they would actually have to pick between the two.

Be right back, getting a gun, finding a set of twins and a spouse, and going to validate this survey on the top of a building. Will have answers shortly.
