different methods

the different companies use different source population data and different algorithms. For me 23andme was much more accurate than FTDNA and they have different settings to get more accuracy. But with more accuracy you get they are less specific.

For example with the speculative setting :
70% British, 10% Eastern Europe, 8% German, 4% Southern Europe, 6% Broadly European

Under conservative, which is 90% accurate
60% Northwestern European, 35% Broadly European, 2% unassigned

FTDNA
90% British, 5% Eastern Europe , 5% Asia Minor

but most people using these services want more detail than "northwestern Europe" or "Southern Europe" thus the companies speculate. At least 23andme honestly reports the accuracy of the speculative setting as 50% accurate. People do not pay $99 to discover they are European or East Asian , or sub-saharan African since they already know.

Thanks for your answer.
I'm understanding that the problem is the different algorithms use beetween testing society.
Bonne soirée

speculative verse conservative

not just the algorithms, but the level of confidence.

It seems that FTDNA takes a more speculative approach...23andme in the past defaulted to the conservative ancestry report, but most people wanted to see the speculative results (although it is much less accurate than the conservative view)

ancestry

it would be interesting if FTDNA had a conservative setting to see the more accurate results as 23andme offers.
