One in fifty scientists fakes research by fabricating or falsifying data. They make off with government grant money, which they share with their universities, and their made-up findings guide medical practice, public policy and ordinary people’s decisions about things like whether or not to vaccinate their children.

As Ivan Oransky notes in Gaming the Metrics, “the most common outcome for those who commit fraud is: a long career.”
