Ignoring data delays our reaction to emerging public health tragedies like 13 Reasons Why.

We applaud Niederkrotenthaler and colleagues1 for adding another layer of evidence that 13 Reasons Why is harming the public by pushing some individuals toward suicide. However, their dismissal of some of the earliest evidence on this subject deserves a revision not because it undermines their central claim but because it makes it even stronger and can make psychiatric epidemiology more actionable in the future.
