DanBC: "The article mentions a 90% detection success rate, but it doesn't go into rates of false positives (people who aren't scammers who are flagged as scammers) or false negatives;"

Then...

pc86: "Maybe I'm misunderstanding your question, but doesn't 90% detection imply a 10% false negative rate"

Then...

atwebb: explains difference between false positive and false negative.

Then...

pc86: "The question was about false negatives, not false positives. The parent's point was that he wanted to know the false negative rate when they found 90% of fraud attempts. I was asking if that 90% number meant that by definition there was a 10% false negative rate."

But... the parent's point was about false positives, not false negatives. In order to clear up the dialogue I put the definition of each, then re-asked the question which was not previously answered.

The question still stands: What are they going to do about people who are detected as fraudsters who are actually not trying to commit fraud?
