The Boston Globe issued a correction to its big scoop about Sen. Elizabeth Warren’s possible Native American ancestry, showing that their math was off.
The correction note, appearing now at the bottom of the report, reveals that the ancestry percentage of a potential 10th generation relative is actually even lower than originally stated.
The Globe initially reported that Warren has “strong evidence” of Native American heritage, stemming from six to 10 generations back, which would make her at minimum 1/512th (or .19 percent) Native American.
However, the Globe acknowledged that the number actually doesn't even reach the tenths place without rounding up.
“Correction: Due to a math error, a story about Elizabeth Warren misstated the ancestry percentage of a potential 10th generation relative. It should be 1/1,024,” the Globe said in its correction. That would put the percentage at .097.
To put this into perspective, the Republican National Committee shared a link to a 2014 New York Times article which discussed how the largest genetic profile study published at the time found in that European-Americans had genomes that on average held .18 percent Native American ancestry.
At the other end of the range (the end showing the highest likelihood of Native American ancestry), the Globe report said Warren would be 1/32nd American Indian if her great-great-great-grandmother was Native American, but for the sixth generation that figure should be 1/64th. A second correction followed hours later.
Altogether, this would alter the originally stated percentage range from 1/512 - 1/32 to 1/1024 - 1/64.
Warren shared her DNA test results Sunday with the newspaper after pressure to prove her claims that she is Native American. President Trump often mocks Warren, calling her “Pocahontas.”
The Democratic senator from Massachusetts says the positive test results means that Trump has to carry out his promise to donate $1 million to a charity of her choosing.
