A review of news release exaggeration

British and Australian researchers reviewed 534 news releases from major journals and found exaggeration doesn't pay off, Matt Shipman writes: "Taking into account the smaller number of releases that included exaggerations of either kind — limiting the sample size — the most cautious way to interpret these numbers is to say that exaggerations in news releases don’t seem to make much of a difference one way or the other on whether reporters will cover the research."
