A decade ago, smart devices promised to change the way we think and interact, and they have – but not by making us smarter. Eric Andrew-Gee explores the growing body of scientific evidence that digital distraction is damaging our minds.

[...] The evidence for this goes beyond the carping of Luddites. It's there, cold and hard, in a growing body of research by psychiatrists, neuroscientists, marketers and public health experts. What these people say – and what their research shows – is that smartphones are causing real damage to our minds and relationships, measurable in seconds shaved off the average attention span, reduced brain power, declines in work-life balance and hours less of family time.

They have impaired our ability to remember. They make it more difficult to daydream and think creatively. They make us more vulnerable to anxiety. They make parents ignore their children. And they are addictive, if not in the contested clinical sense then for all intents and purposes.

[...] Smartphones are "literally using the power of billion-dollar computers to figure out what to feed you," Mr. Harris said. That's why you can't look away.
