The best science reporters earn their keep by balancing "wow!" and "really?" at moments like this. Sometimes it's a matter of spotting an outright hoax (i.e. Piltdown Man fossils in the 1920s.) Other times, what's at stake is an overly decisive attempt to interpret exciting data that might not be so exciting after all. The cold-fusion "discoveries" of 1989 fall into that camp, along with this gravitational-wave claim. It's hard for journalists to referee everything in the first few hours. But by talking to other experts in the field, and by being willing to comb through the methodology underlying the claims, it's possible to get a sense within a few days (weeks?) of what's holding together very, very well, and what's starting to seem a little shaky. There's nothing wrong -- and a lot right -- with writing post-announcement articles that acknowledge such uncertainties.
