    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.
