Scientific studies show that the risk of misidentification from partial DNA matching in familial DNA searching is very low.
NOT BSTOTAL BS
MOSTLY BS — Verdict: Mostly False
Verified by Lenz ·
The Short Version
The claim overstates what the literature shows. Some studies do find extremely low false-positive rates for one narrow error type: unrelated people being flagged as close relatives under strict methods. But familial searching also produces meaningful misidentification risks in other important scenarios, especially confusing distant relatives with first-degree relatives, so the blanket “very low” characterization is not supported.
Caveats
The phrase “very low” is only defensible for certain protocols and a specific error type, not for familial searching overall.
Distant relatives can be misclassified as close relatives at nontrivial rates, which materially affects real-world investigative risk.
Error rates depend on thresholds, marker sets, database composition, and population structure, so results are not universally transferable.
