Nota, they already use things that approach being able to know what you will do using psychometrics. Remember the Cambridge whistle blower? Do you think he was making that up? So they get you to vote a certain way, or feel a certain way, or buy a certain product....that's all fine...but stopping someone from being murdered....oh no! Nota bene draws the line at stopping murder! Come on, think that through.
If we knew with sufficiently high probability person X was going to kill someone tomorrow, and instead we put them in rehabilitation that was genuinely interested in his health outcome being positive, that would be a tragedy in your eyes? But the murder...not a tragedy?
I think you're wrong, and i think if you think about it, you'll agree. If you know a family member who is unstable, and you know from your close and love-driven ties to them they are at the tipping point, does Nota Bene:
1. ignore it because freedom!
2. intervene because you love them.
Come on, I know you'll do the right thing.
