Anyone who has a sibling knows that sibling rivalry exists. It may not be at the forefront of the relationship, but there is always, and I mean always, some sort of competition between siblings, even if it's never addressed or discussed. But because some scientists apparently decided that there wasn't quite enough sibling rivalry in the world, they did a study, documented the conclusions, then shared them with the world to see. I've already texted my sister calling foul on this whole thing.
