The most interesting result is the least expected result that doesn't include bad news. Outside relatively small circles, the vast majority of white people will lose none of their privilege or social position if they find out their ancestry includes something unexpected. It's clearly pretty widespread too, because all of the 23andMe advertising includes people ostensibly of European descent who find out they've got unexpected ancestry.
In US, varied ancestry is a norm if I'm not mistaken, so having a "pure" heritage makes you unique. In many countries it's the opposite - the default is "pure" heritage, and having varied background is what makes you stand out.
Also, from the health perspective, varied ancestry is better if I'm not mistaken. Kind of like pure breed animals being less healthy in general, compared to mixtures.
I'm 99.5% European (86% Eastern European), and 0.5% East Asian/Native American. I hoped for more varied ancestry when I received the results.
There's dignity in guilt, and it's essential for growth. You really don't seem to understand the human condition.
It's something odd. As if they are somewhat uncomfortable on their own skin. Shame is the wrong word, but i can't find the right descriptor. On the other hand, i think this points to social pressures that make people feel that way about themselves.
