Worst part is (in my view) that they wont be known to be "incorrectly flagged" until after a human has dealt with them. Initially they will just be a "flagged" person (incorrectly or not) and so the immediate bias (unconcious or otherwise) for the human operator will be "this person is a liar".

This is going to be awful - imagine all the people who are anxious anyway, perhaps dont speak the langauge very well, get confused by the questions etc. There are going to be a lot of people who will get "enhanced screening" and generally treated like a criminal for no other reason than "the computer said you are a liar".

Awful.
