> Why do people assume ancestry results from these DNA tests are "accurate"?

Years of highly visible advertising by these companies which implies they're accurate? All of those “discovery your ancestry” posters they put up around here had specific countries and locations.

Agreed. Just a quick look at the 23andme site doesn't show me anything that says they are "estimates" or "not accurate".

The landing page shows me this headline "This new year, commit to a healthier you - inspired by your DNA." I'm sure they have it legally covered somewhere in their TOS but it's still not good if these are inaccurate or estimates.
