Wanted: The 'perfect babysitter.' Must pass AI scan for respect and attitude.

When Jessie Battaglia started looking for a new babysitter for her 1-year-old son, she wanted more information than she could get from a criminal-background check, parent comments and a face-to-face interview. So she turned to Predictim, an online service that uses "advanced artificial intelligence" to assess a babysitter's personality, and aimed its scanners at one candidate's thousands of Facebook, Twitter and Instagram posts. The system offered an automated "risk rating" of the 24-year-old woman, saying she was at a "very low risk" of being a drug abuser. But it gave a slightly higher risk assessment -- a 2 out of 5 -- for bullying, harassment, being "disrespectful" and having a "bad attitude." The system didn't explain why it had made that decision.
