"If your child was going swimming, especially if the waters might be choppy, you’d give them a lifejacket and you’d teach them how to swim. Learning how to spot fake news, understanding why it’s not good and knowing what to do about it is like that. If our kids are going to dive into the choppy waters of the internet - and they are, whether we like it or not - we’d better make sure they know how to swim." I interview journalist and author Joyce Grant about her new book Can You Believe It? How to Spot Fake News and Find the Facts.
