Dutch scandal serves as a warning for Europe over risks of using algorithms

Chermaine Leysner's life changed in 2012, when she received a letter from the Dutch tax authority demanding she pay back her child care allowance going back to 2008. Leysner, then a student studying social work, had three children under the age of 6. The tax bill was over €100,000. "I thought, 'Don't worry, this is a big mistake.' It was the start of something big," she said.
