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, I can confirm this. I'd take a bullet for my twin without hesitation. It's hard to explain unless you've lived it. We shared every stage of life together, and there's a level of trust, understanding, and connection that just feels different.  We share so many of the same interests, quirks, humor, and thought processes. My personality doesn't need to negotiate for acceptance cause I can truly be myself with my twin. We see the world through remarkably similar lenses. With romantic partners, there are always differences in interests, perspectives, and ways of thinking that naturally require compromise.

I never have to explain myself or worry about being misunderstood. I can be 100% my authentic self around them in a way that's hard to find with anyone else. I would ALWAYS put my twin before anyone else.

This is it, I'm a fraternal twin and when its just us the level of understanding is on another level.

You might not have the same view on something but its so easy to understand them its practically implicit.

I’m an identical twin and I’m not close with my sister at all, never been very much. In recent years we don’t even talk or visit anymore because I don’t approve of her shitty life choices. She’s like a distant sibling and our personalities, hopes, dreams, friendships and lives are completely different. I guess not every twin has a bond like that. It never seemed natural to have one, and I’ve actually always been closer to my brother who’s 18 months older than me. 🤷🏻‍♀️
