I agree it's odd, and yet still shared that sense of disappointment in the lack of surprises in my 23andMe report. I also don't think it's entirely irrational.

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.
