Are you a future criminal? You might not think so, says data scientist Seth Stephens-Davidowitz, but what do you look like on paper? Have you ever searched something suspicious online? Ever been curious about a dark topic? Just like the film Minority Report, where "future murderers" are arrested before they commit their crimes, we have a similar predictive tool ready-made: Google's search data. People really do search for things like 'how to kill your girlfriend' or 'how to dispose of a body', but as Stephens-Davidowitz points out, it’s not supposed to be illegal to have bad thoughts. Beyond privacy and ethics, data science also backs the idea that you can't predict with any accuracy who will commit a crime, as he says: "a lot of people have horrific thoughts or make horrific searches without ever going through with a horrific action." Data also provides intriguing correlations about who or won't will pay their loans based on a single word used in their loan application, and reveals the questions people in the Bible Belt are too afraid to ask aloud. This kind of data in the wrong hands can leave people vulnerable to discrimination or worse, if society lets its ethics slide. Stephens-Davidowitz is the author of Everybody Lies: Big Data, New Data, and What the Internet Can Tell Us About Who We Really Are.
