To it he has added an additional set of Amelia Earhart's 'actual' bone measurements as supplied by TIGHAR's amazing photo analyst Jeff Glickman who is able to make highly accurate measurements from grainy photos through flesh and clothing.
"According to the authors of the program, there are limitations that should be taken into account when using this program. Some of these limitations include the fact that ForDisc will classify any unknown into the ‘closest’ group, this means that even if an individuals ethnic group or race is not represented in the database, the program will classify it to the ‘closest’ group...
...The last limitation deals with archaeological populations. This limitation is due to the fact that most of the measurements in the data set that the classifications are based on in the program are from remains that are from the 20th century, and should not be used for classification of archaeological remains...
A 2009 study found that FORDISC 3.0 "is only likely to be useful when an unidentified specimen is more or less complete and belongs to one of the populations represented in its reference samples", and even in such "favorable circumstances it can be expected to classify no more than 1 per cent of specimens with confidence."
In 2012 research was presented at the 81st Annual Meeting of the American Association of Physical Anthropologists, which concluded ForDisc ancestry determination was not always consistent, and the programs' recommended acceptance criteria did not separate correct and incorrect determinations. The authors concluded that the program does not perform to expectations and should be used with caution."
