Terrible title. It’s implying the study is something about the accuracy of finger printing. It’s a study where Ai was able to find some similarities in finger prints to different fingers in the same person, and sometimes could guess if they were different fingers from the same person, though not very consistently. I’m not making any judgements on the accuracy of forensic fingerprinting techniques here but that’s not what this article or study is about.

Worst title ever

Tarot cards for cops.

This student seems both cocky and clueless in equal measures. Fingerprints are not one of a kind, it’s a very useful method as they rarely repeat exactly but they do so are not used in isolation but rather as part of a case.

I’m not sure why he’s going on about different fingers on the same person being similar but not the same, that’s known and kind of irrelevant, you can’t convict someone with “your fingerprints are kind of similar to this one” without further convincing evidence.
