Many have voiced their concerns about the accuracy, or lack thereof, of the AncestryDNA autosomal test.
I noticed that you have a Bachelor of Science degree in Physics and I am interested to know your opinion about something. Since we are provided nothing by way of raw data, methodology or a means to reproduce AncestryDNA's results, how can you advocate this test if it does not meet the requirements of the scientific method?. (see definition below)
Thanks in advance,
Scientific inquiry is generally intended to be as objective as possible in order to reduce biased interpretations of results. Another basic expectation is to document, archive and share all data and methodology so they are available for careful scrutiny by other scientists, giving them the opportunity to verify results by attempting to reproduce them. This practice, called full disclosure, also allows statistical measures of the reliability of these data to be established (when data is sampled or compared to chance).
