If you know even a little about how companies use personal data to make uncannily precise guesses about our future behavior, you know it would be child’s play to flag potential mass killers. They do it to sell soap flakes. They can do it to save lives.https://twitter.com/nickconfessore/status/1077194681103142912 …

All people eventually buy soap. 99.9999% of people never commit mass murder. It is a lot harder problem.

Actually that makes it easier, not harder. The behavior pattern is going to be relatively rare, and so easier to spot as an outlier, and the bad guys will be a subset.

No, it doesn't. The people who will commit murder are a tiny subset of the people who have the purchasing patterns of those who will commit murder and the consequences of false positives are a lot greater than missing your guess on soap purchases.

If the Minority Report algorithm is 99% accurate (identifies future killers w/ 99% accuracy) and the true prevalence of such killers is 0.001% (500/50m people) then false positive rate is 1%, or 500,000 people. For every future killer caught, you’ll falsely accuse a half million.

Back here in reality, there is a wide range of decision points between flagging an activity as potentially suspicious and hauling someone in to court. Cops can and do make such distinctions every day.

So the idea here is to flag thousands of potential mass murderers, send data on them to the police, and have the police dig into their private lives?
